Opis:

The pollution of surface water and sediments by heavy metals has become a difficult thing to deal with due to their toxicity and accumulative behavior. The present study was undertaken to provide information on the concentrations and distribution of selected heavy metals in surface water and sediments from Warri River, and to compute a contamination/pollution index of heavy metals. Surface water and sediment samples were collected using standard methods and then analysed for nine trace metals. These metals were determined using a Flame Atomic Absorption Spectrophotometer – UNICAM 929. According to our results, the mean concentrations of the select metals in the sediments were higher than those of the surface water. The figures, however, varied significantly in the six sample locations (SW1–SW6). In the sediments, the highest mean concentration was of Fe (504.13 mg/kg) in location SW1, whereas in surface water, generally, the highest mean concentration was of Fe (1.23 mg/l). In other words, mean metal levels in the sediments exceeded those of surface water. This indicates that sediments are a sink for metal pollution loads. Computation of contamination/ pollution index in sediment matrix revealed that Cd moderately polluted the sediment, Zn, Fe, Ni slightly, yet significantly contaminated the sediment, while Cu, Cr and Mn very slightly contaminated the sediments. The mean values of metals in this present study were compared with other values reported by other researchers. The higher than normal metal values were attributed to anthropogenic wastes, runoff, refinery jetty and varied petroleum related activities in the area.

Opis:

Water pollution in rivers is still a crucial problem for the countries that use river water as the primary water source. This study aimed to determine the water quality of the Musi river and the content of heavy metals in water, sediment and mussels as well as to predict the water quality of the Musi river in the next five years. The water samples were taken from 18 stations (sampling points) from upstream to downstream to be checked physically, chemically and biologically. Prediction of the river water quality was made using the QUAL2Kw software. The research results show that the Musi River water is categorized as lightly polluted with concentrations of TSS and DO that have passed the threshold. The heavy metals in river water, such as Pb and Cr have also passed the quality standard. The Fe, Mn, and Zn concentrations are pretty high in the sediment. In turn, in mussels, the metals measured were Fe, Cu, and Zn. The prediction results reveal that several values of the river quality parameters will pass the threshold value with the same pattern tendency from each station.

Opis:

The leachate coming from the landfill is a serious problem. This is because the leachate water can contaminate the wells of the residents around the landfill. This research was conducted at Jabon Landfill located in Jabon District of Sidoarjo Regency, East Java Province, Indonesia. Jabon Landfill has been operating since 2003 with a controlled landfill system that has triggered environmental risks due to the leachate output. The purpose of this study was to determine the classification of the shallow groundwater quality status based on the pollution index (PI) around Jabon Landfill at a distance of around 250 meters, 500 meters and 1,000 meters from the landfill. The pollution index was determined by analyzing the pollutant concentration consisting of these following parameters: pH, BOD, COD and Fe. The results of the analysis show that the pH parameter had a higher value than the pH at Jabon Landfill of 7.2–7.5. The pH at Jabon Landfill was 6.35. The Fe parameter shows that the value of 1.694 in the groundwater well closest to Jabon Landfill and the wells further away indicates that the Fe concentration was lower for the latter, namely 0.081 at a distance of up to 200 meters. On the basis of the Pollution Index, the highest value was 5.45 at Well 7 is located 196 m from Jabon Landfill. Meanwhile, the well furthest from Jabon Landfill at a distance of 1,000 m showed a lightly polluted status with a Pollution Index of 1.91. The further the location of the well away from Jabon Landfill, the Pollution Index value tended to decrease. This means that the pollution status generally improves. Overall, the pollution status of the 18 wells shows that 2 wells are moderately polluted, 15 wells are lightly polluted and 1 well is in good condition.

Opis:

White leg shrimp (Litopenaeus vannamei) is known as a prime aquacultural commodity in Indonesia. However, the rapid growth of shrimp farming has resulted in widespread destruction of coastal ecosystems, including mangrove swamps. Intensification of shrimp culture has led to many other environmental problems. Integration of mangroves into aquaculture systems (IMAS) should be considered as a way to preserve the mangrove ecosystem as well as sustainability of the aquaculture business by treating the influent and effluent water. This study aimed to assess the benefits of integrating mangroves into shrimp aquaculture, in terms of water quality. The results showed that temperature, dissolved oxygen (DO), and nitrite levels in the water significantly differed between sample sites. PCA analysis indicates that total organic matter (TOM), nitrates, nitrites, and ammonia were the principal factors in the overall water quality of the ponds. The highest pollution index was found in the super-intensive shrimp ponds ('moderately polluted'), while the other sites, including the mangrove area, were categorized as 'lightly polluted'. These findings suggest that the presence of mangroves may improve the quality of aquaculture wastewater, but the pollution index may still not reach the 'good' category. It is therefore recommended that a wastewater treatment plant be installed to support the integrated aquaculture system.

Opis:

Comprehensive Environmental Pollution Index (CEPI) is a rational number to characterize the quality of the environment at a given location following the algorithm of source, pathway, and receptor. As CEPI increases, there will be adverse effects on the receiving environment. Central Pollution Control Board (CPCB) has brought out revised criteria for evaluation of CEPI by replacing the criteria issued in 2010. The revised criteria are issued to overcome the subjectivity factors of health impact studies on humans, flora and fauna. Kurichi Industrial Cluster in Coimbatore District is an engineering industrial estate housing foundries, forging units, metal finishing and fabrication units. In January 2010, the Ministry of Environment and Forests, Government of India declared Kurichi as critically polluted area and imposed moratorium on new projects and for expansion of the existing units. This declaration was made based on the CEPI score which was calculated as more than 70. Thereafter, the industries and the local stake holders have implemented various pollution control measures and hence the CEPI score has come down less than 70 and so the moratorium was lifted in October 2010. In this paper, the CEPI score is calculated based on the revised criteria and using the environmental quality monitoring data collected in April 2017. It is found that the CEPI score is below 70 which imply that the industrial units are operating and maintaining the pollution control measures consistently. However, taking a policy decision based on the CEPI score, one should be cautious on the adequacy of data and the parameters selected.

The purpose of this study is to evaluate the level of heavy metal contamination in the spoil heaps of the former Ain Aouda mine (Taza). In this regard, solid samples of the study area were sampled. The set of analyses carried out have detected the presence of zinc (Zn), lead (Pb), copper (Cu), arsenic (As) and nickel (Ni) that remain in these metal discharges. The calculation of contamination/pollution indices: the Geo Accumulation Index (Igeo), the Enrichment Factor (EF) and the Pollution Index (IP) were used to predict the extent of heavy metal contamination. The results of this study suggest that the spoil heaps reveal polymetallic contaminations allowing the trace metal elements to be classified in the following order Zn ˃ Pb ˃ As ˃ Cu > Ni. Knowing well that the alteration and erosion of this stock of mine waste could contribute to the degradation of the natural environment by these elements that are present.

Opis:

Batujai reservoir is located in Central Lombok Regency, Indonesia. The government and local people use it for hydropower generation, drinking water, agricultural irrigation, fish farming, and tourism. The phenomenon of growing population and increasing industrial activities in the catchment area of Batujai reservoir always result in the discharge of various pollutants into the aquatic environment and cause the blooming of water hyacinth over almost 30% of the reservoir area. The aim of this study was to determine the water pollution index of Batujai reservoir. The samples were analysed for the following parameters: pH, temperature, DO, COD, BOD, TSS, and heavy metals. The research was done by using purposive sampling method and determination of water quality status with STORET method based on Government Regulation No. 82/2001. The measurement results show that the physical and chemical parameters of the Batujai reservoir water do not exceed the quality standard are the temperature (29 to 32°C); pH (6.6 to 7.5 mg/L); nitrate (0.421 to 0.546 mg/L); Cd (0.0005 to 0.005 mg/L); Cr (<0.001 to 0.018 mg/L); and the parameters that exceed quality standards are DO (3.8 to 4.9 mg/L); BOD (3.03 to 4.21 mg/L); COD (6.8 to 10.1 mg/L); phosphate (0.181 to 0.237 mg/L); and Pb (0.14 to 0.24 mg/L). The water quality status of Batujai reservoir was heavily polluted for standard quality on class I, II, III and moderately polluted for class IV.

Opis:

The eventual polluting of the Ouichane region’s groundwater by heavy metals around an abandoned iron mine was investigated. To reach this aim, the research began with a questionnaire survey to assess local people’s use of and appreciation for well and spring water, followed by measurement of spatial pollution load of heavy metals: Al, Ag, Fe, Cd, As, Cr, Co, Zn, Pb and Cu for water samples collected from twelve wells and three spring drinks of water using inductively coupled plasma-atomic emission spectrometry method (ICP). Determining the overall quality of spring and well water for human use was also performed by calculating the heavy metal pollution index (HPI). As result, the survey revealed that 44.90% of the households are not connected to the drinking water network, 97.3% of them use well water, which is highly appreciated, and 88.1% of the population consider its quality to be good to excellent. Meanwhile, the ICP analysis showed that all the water samples contain heavy metals. In fact, the maximum concentrations (expressed in 10-5 g/l) recorded per element were 9.7 for (Ag), 15 for (Al), 6.9 for (As), 4.5 for (Cd), 5.6 for (Co), 31 for (Cr), 14 for (Cu), 858 for (Fe), 7 for (Pb) and 2.9*10-5 g/l for (Zn). Moreover, most of the water samples recorded heavy metal values above World Health Organization (WHO) limits, for at least one metal among the ten tested, with high concentrations of iron observed in all samples. The HPI values for the three explored sources (S1, S2 and S3) and for 8 out of 12 wells (P3, P4, P5, P6, P7, P8, P9 and P10) exceed the critical pollution value and identify non-potable water with a high potential of contamination. Consequently, the results of this study raise the question about groundwater around this abandoned mining area, especially in the long term, the use of groundwater could increase because of the succession of years of drought on Moroccan territory and hence may constitute a significant health risk for most of the inhabitants.

A total of 316 soil samples in the An Giang province were collected from the industrial zone (48 samples), mining (40 samples), farming (112 samples), landfills (88 samples) and cemeteries (28 a samples) to analyze toxic elements, including Cu, Zn, Pb, Cd and As. The geoaccumulation index (Igeo), pollutant load index (PLI) and potential ecological risk index (RI) were used to assess pollution levels and ecological risks. The results showed that the concentrations of heavy metals were almost still within the allowable limits of national standards. Cd was not detected. Heavy metals were detected in the soil in the following order: As < Pb < Cu < Zn, mining < industrial < landfill < cultivation < cemetery areas. The heavy metals contributing to soil environmental variability were similarly identified in the cemetery with industry and landfill with farming. The value of Igeo shows that As has a high potential to accumulate in soil in all land uses. The ranges of PLI values presented that the soil in industrial, farming, mining and landfills areas were classified moderate, while the cemetery areas has been rated at a high level. The RI values identified very high, high, and moderate ecological risks for cemetery, industrial and farming land and landfill, mining, respectively. The combination of PLI and RI indices showed that the cemetery areas were at the highest levels of pollution and risk. The results of this study provide scientific information on pollution level and ecological risks in various land use types supporting environmental zoning and managing strategies in the An Giang province.

Opis:

Aluminium slag waste is a residue from aluminium recycling activities, classified as hazardous waste so its disposal into the environment without processing can cause environmental problems, including groundwater pollution. There are 90 illegal dumping areas for aluminium slag waste spread in the Sumobito District, Jombang Regency. This study aims to evaluate the quality of shallow groundwater surrounding aluminium slag disposal in the Sumobito District for drinking water. The methods applied an integrated water quality index (WQI) and heavy metal pollution index (HPI), multivariate analysis (principal component analysis (PCA) and hierarchical clustering analysis (HCA)), and geospatial analysis for assessing groundwater quality. The field campaign conducted 40 groundwater samples of the dug wells for measuring the groundwater level and 30 of them were analysed for the chemical contents. The results showed that some locations exceeded the quality standards for total dissolved solids (TDS), electrical conductivity (EC), and Al2+ . The WQI shows that 7% of dug well samples are in poor drinking water condition, 73% are in good condition, and 20% are in excellent condition. The level of heavy metal contamination based on HPI is below the standard limit, but 13.3% of the water samples are classified as high contamination. The multivariate analysis shows that anthropogenic factors and natural sources/geogenic factors contributed to shallow groundwater quality in the study area. The geospatial map shows that the distribution of poor groundwater quality is in the northern area, following the direction of groundwater flow, and is a downstream area of aluminium slag waste contaminants.

Warna and Pengilon Lakes are very close to each other and connected with the sill, a famous tourist destination in the Dieng Plateau Java. Land-use changes are the main problem that affected the lakes. The conversion of forest into an agricultural area had induced erosion and increased the volume of nutrients discharged to the lake due to high use of fertilisers in potatoes farms. In the dry seasons, water from those lakes was pumped to irrigate agricultural land. This study aimed to determine the water quality of Warna and Pengilon Lakes based on physical, chemical parameters, and phytoplankton communities. Water samples were collected from 4 sites at each lake to analyse biological oxygen demand (BOD), chemical oxygen demand (COD), ammonia, nitrate, nitrite, and total nitrogen (TN). Temperature, pH, dissolved oxygen (DO), turbidity, and conductivity (EC) were measured in-situ. During this research, turbidity and BOD in Warna and Pengilon Lakes exceeded the Indonesian water quality standard. Based on the STORET method, the water quality of Lake Warna was assessed as highly polluted for all classes. However, based on the pollution index (PI), Lake Warna was slightly to moderately polluted, as well as the saprobic index was in the β-mesosaprobic phase. Based on the species diversity index of phytoplankton, both Warna and Pengilon Lakes were moderately polluted. The long-term monitoring studies are necessary as an early warning sign of water quality degradation. Therefore, they provide insight into the overall ecological condition of the lake and can be used as a basis for developing suitable lake management.

A good water quality is essential to sustaining the life of the organisms. The determination of water quality is needed as a direction to monitoring the water pollution. The purpose of this study is to examine the quality of the water and to determine the water pollution index based on the physicochemical parameters in Mimika waters, Indonesia. The sampling of water quality was carried out in October 2016 at six stations (Moga, Puriri, Inaoga, Keakwa, Atuka and Pomako waters). Then, the results were compared with the standard of sea water quality for biota marine based on the Decree of the Minister of Environment No. 51 year 2004. This study showed that the physicochemical parameters of the waters, such as water turbidity, BOD, NH3 and heavy metals (Hg, As, Cd, Pb, Cu, Zn, Ni and Cr), are still appropriate to the biota marine in all study stations. However, there is a parameter for which the quality standards were exceed in all locations, including water salinity for coral and seagrass, NO3, PO4 and H2S. The result of pollution index calculation at coastal waters Mimika are classified as lightly polluted (Keakwa and Pomako waters), and moderately polluted (Moga, Puriri, Inaoga and Atuka waters) with the pollution index values of 3.51 to 6.95. It is important to notice that the parameters of quality standards which had been exceed such as NO3, PO4 and H2S are the environmental parameter for nutrient elements and can trigger eutrophication in the waters.

Celem pracy było przeprowadzenie analizy możliwości wykorzystania indeksu zanieczyszczenia odcieków (LPI, Leachate Pollution Index) do oceny stanu zanieczyszczenia wód odciekowych, z wykorzystaniem wyników prowadzonego monitoringu oraz przy poszerzonym zakresie badań. Na podstawie przeprowadzonej analizy można zauważyć, że wykorzystanie do oceny właściwości wód odciekowych wyników oznaczeń w obowiązującym zakresie jest mało efektywne i może dostarczać niepełnych informacji na temat rzeczywistego oddziaływania składowiska na środowisko wodne. Obowiązujący zakres badań właściwości fizykochemicznych wód odciekowych powinien zostać zweryfikowany, ponieważ opiera się w dużej mierze na badaniach zawartości metali ciężkich, nie uwzględnia natomiast pozostałych parametrów, które charakteryzują się dużą zmiennością. Wykazano, że dodanie zaledwie 3 parametrów oznaczanych w ramach obowiązującego zakresu monitoringu, może zmienić znacząco wyliczoną wartość wskaźnika LPI, a tym samym dostarczyć dodatkowych informacji na temat zanieczyszczenia wód odciekowych na danym obiekcie.
The purpose of the work was to analyze the possibilities of using the leachate pollution index (LPI) to assess the state of contamination of leachate waters, using the results of monitoring and extended scope of research. Based on the conducted analysis, it can be noticed that the use of the results of determinations in the current scope for the assessment of the effluent waters is ineffective and may provide incomplete information on the actual impact of the landfill on the aquatic environment. The valid range of the physicochemical properties of leachate waters should be verified, because it relies heavily on the study of heavy metal content, but does not take into account other parameters, which are characterized by high variability. It has been shown that the addition of only 3 parameters determined within the scope of the monitoring scope in force may change the significantly calculated LPI value, and thus provide additional information on the contamination of leachate waters at a given facility.

Opis:

This study aims to assess the water quality and determine the pollution index of the Bedadung River in the urban-area segment of Jember Regency, East Java. The sampling in the urban segment of Jember was conducted in May 2019 at five different locations, namely Slamet Riyadi Street, Mastrip Street, Bengawan Solo Street, Sumatra Street, and Imam Bonjol Street. The pollution index assessment refers to the Decree of the State Minister for the Environment of Indonesia Republic number 115 of 2003. The analysis showed that the parameters of TDS, TSS, pH, COD, BOD, NH3-N, Co, Cd, Cu, Zn, H2S, Cl–, SO4, oil and fats, MBAS, NO2-N, Fe, Pb, F, Cl2, NO3-N, phenol, and As did not exceed the quality standards. The parameters PO4, CN, total coliform, and faecal coliform were found to breach the quality standards at the 5 water sampling points. Total coliform and faecal coliform were the dominant pollutants in this segment. Therefore, the parameters of PO4, total coliform, and faecal coliform were considered as indicators of pollution arising from domestic and agricultural activities. The pollution index values for the five sampling locations ranged from 7.21 to 8.23. These scores indicate that the Bedadung River section that passes through the urban segment in Jember is classified as being in the moderately polluted category. This preliminary rapid assessment is therefore one of the considerations for the management of water quality in the Bedadung River section that passes through the urban area of Jember.

Opis:

Air pollution arises mainly from automobiles and industries is well known fact. Monitoring and detection by instrument cannot be possible everywhere however, indication from plant species by their alterations in leaf morphology and anatomy may be a suitable easy screening measurement. The present study aims to detect morphological features with special reference to gall quantification and anatomy of leaves of Alstonia scholaris R. Br., found in eastern Indian urban and suburban area that are exposed to vehicular emission. The results indicated alterations of leaf morphology along with length (L), breadth (B), L/B ratio and significantly increased (P < 0.001, 0.01 and 0.05) Air Pollution Index (API). It is concluded that vehicular emission can be monitored as an early indication through increased API in A. scholaris. Further research would be needed in relation to secondary metabolites alteration, biochemical and genetic parameters to know pollutant susceptibility as an indicator. In addition, anatomical abnormalities in gall formation as well as numbers were also pronounced in leaves exposed to various load of air pollution.

Opis:

The Timok River (202 km long, 4547 km2 basin area) is located in East Serbia. It is a right tributary of the Danube River and one of the most polluted watercourses in Serbia. On the basis of the data provided by the Republic Hydrometeorological Service of Serbia, the paper presents an analysis of water quality and pollution using the combined physico-chemical WPI index (Water Pollution Index) calculated for two periods - 1993-96 and 2006-2009 at four hydrological stations: Zaječar-Gamzigrad (Crni Timok River), Zaječar (Beli Timok River), Rgotina (Borska Reka River) and Čokonjar (Timok River). The following parameters were taken into consideration: dissolved O2, O2 saturation, pH, suspended sediments, Five Day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (CODMn), nitrites, nitrates, orthophosphates, ammonium, metals (Cu, Fe, Mn, Hg, Ni, Zn, Cd), sulphates and coliform germs. The average WPI values were calculated for the observed periods based on the comparison of the annual average values of the listed parameters and defined standard values for the I water quality class (according to the Regulation on the Hygienic Acceptability of Potable Water of the Republic of Serbia). The highest pollution degree was recorded in the Borska Reka River, where heavy metal levels (especially manganese and iron) were significantly increased. These metals are indicators of inorganic pollution (primarily caused by copper mining). Also, increased values of the organic pollution indicators (ammonium, coliform germs, Five-Day Biological Oxygen Demand - BOD5) in the Borska Reka and the Timok rivers are the result of uncontrolled domestic wastewater discharge.

Opis:

Shatt Al-Arab River in Basrah province, Iraq, was assessed by applying comprehensive pollution index (CPI) at fifteen sampling locations from 2011 to 2020, taking into consideration twelve physicochemical parameters which included pH, Tur., TDS, EC, TH, Na+, K+, Ca+2, Mg+2, Alk., SO4-2, and Cl-. The effectiveness of multiple linear regression (MLR) and artificial neural network (ANN) for predicting comprehensive pollution index was examined in this research. In order to determine the ideal values of the predictor parameters that lead to the lowest CPI value, the genetic algorithm coupled with multiple linear regression (GA-MLR) was used. A multi-layer feed-forward neural network with backpropagation algorithm was used in this study. The optimal ANN structure utilized in this research consisted of three layers: the input layer, one hidden layer, and one output layer. The predicted equation of the comprehensive pollution index was created using the regression technique and used as an objective function of the genetic algorithm. The minimum predicted comprehensive pollution index value recommended by the GA-MLR approach was 0.3777.

Opis:

W Polsce brak jest regulacji prawnych określających dopuszczalne wartości wskaźników zanieczyszczeń oznaczanych w odciekach. Otrzymane wyniki często porównuje się z danymi dotyczącymi odcieków z innych składowisk. Porównywanie odcieków na podstawie wartości poszczególnych wskaźników zanieczyszczeń może być jednak dosyć uciążliwe i czasochłonne. Rozwiązaniem sytuacji może być zaproponowany przez Kumar i Alappat indeks zanieczyszczeń odcieków (Leachate Pollution Index – LPI), określający ogólny potencjał zanieczyszczeń niesionych przez odcieki składowiskowe. Może być on wykorzystywany do klasyfikacji/rankingu składowisk ze względu na jakość odcieków, śledzenia zmian jakości odcieków, badań naukowych czy nawet jasnego przekazywania społeczeństwu informacji dotyczących jakości odcieków.
In paper, the comparison of the leachate contamination of two active and two closed landfills site is presented. Leachate quality was assessed, using the Leachate Pollution Index (LPI). For the LPI calculation of a leachte quality data from the years 2004-2011 was used. Value of calculated LPI for all the analyzed landfills does not exceed 6. It indicates that process of decomposition of organic matter is in stable phase. The largest variations of the LPI values were reported to the active landfill O2. They result from the quantity and quality of differentiation of landfilled waste. LPI values, calculated for closed landfills were similar and have no substantial differentiation during the study time. There were no significant statistical differences between the LPI values of the analyzed landfill.

Opis:

Coastal areas in Anantigha are utilized as dumpsite for industrial and domestic wastes including effluent from local industries and inhabitants of the area despite their usage for crop cultivation. Thus, the present study was designed to assess the concentration, pollution load and ecological risk of heavy metal in Anantigha coastal area. Standard pollution indices such as contamination factor (Cf), degree of contamination, pollution load index (PLI), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index were deployed to assess the level of heavy metals contamination in the area. The results showed that the sediment was acidic under dried conditions and low in conductivity. The mean concentration levels of all the heavy metals were lower than their mean background values except for Al. The orders of dominance for concentration of heavy metals were: Al>Fe>Mn>Cu>Zn (Station 1) and Al>Fe>Mn>Zn>Cu (Stations 2, 3 and 4). Analyzed data showed that the sediments in the area are contaminated with Al with Igeo result showing station 2 and 4 been moderately to heavily contaminated with Al while station 4 was heavily contaminated with aluminium. Station 1 had low degree of contamination, whereas station 2 and 4 had moderate degree of contamination, and station 3 showed considerable degree of contamination. The PLI result indicates unpolluted condition and the area were not enriched by the studied heavy metals as shown by EF values. Hence, the sediment in Anantigha coastal marine area was classified as having low ecological risk factor. However, the levels of these metals are not static; there is tendency for increase as a result of increased human input and activities. Hence, there is a need for regular soil testing.

The precise determination of trace element concentrations in the soil of the Al-Qadisiyah Governorate is part of the Iraqi sedimentary plain is required to eliminate high levels of harmful elements in polluted soils. The soil samples were collected from 28 representative profiles in Al-Shamiyah city. The soil profiles were defined using virtual characterization. In this study, I-geo was used to analyze soil pollution. The goals and destinations of the I-geo readings Contamination of Cd, Ni, Pb, and Zn in various soil strata. I-geo (Cd) generally range from 0.58 to 4.71, I-geo (Ni) range from 0.09 to 4.07, I-geo (Pb) ranged range from 0.07 to 2.79, and I-geo (Zn) ranges from zero to 2.79, depicting the local differences in I-geo for pollutants in the research area. Suggesting that the research area had been heavily polluted from Cd in the varied layers of the soils. On the maps pertaining to Zn and Pb, the majority of the research area was primarily covered in the orange and blue hues, suggesting that a significant portion of the research area was likely to be severely polluted from Cd and Ni. Moreover, the land cover layouts of Ni in layers of the soils revealed concentrations rising towards to the western sections, which could be attributed to proximity to a major drain. The results display that its I-geo value of four trace metals generally range from non-pollute to significantly heavily polluted. The I-geo data show significant differences in levels of the Ni, Cd, Zn, and Pb in different soils strata. Including these findings, the soil in Al-Shamiya, Al-Qadisiyah Governorate contains high levels of Cd, Ni, Pb, and Zn. Industries of fossil fuel combustion, as well as other man-made wastes include agricultural nutrients, soil conditioners, and sludge, particularly, ammonium phosphate pollution in soils. The pollutant load index (PLI) reveals a baseline level of contamination in 28 locations, as well as a decline in soil quality in four others. Finally, assessing the danger of contamination for trace metals utilizing the I-geo and PLI by using the GIS method and multimodal models is a helpful and relevant strategy.

Opis:

This study aimed to analyze the heavy metal contamination in sediments and their potential ecological risks. The sediment samples were collected using PVC pipes and grab samplers at nine study sites in Youtefa Bay, namely five sites in the mangrove ecosystem, two sites in the estuary, and two sites in the middle of the bay. The heavy metal content was analyzed using Atomic Absorption Spectrophotometry. The results of the analysis of the heavy metal content in the sediment were in the following order: Zn > Cu > Pb > Ni > Cr > Cd > As > Hg (106.077±98.857, 28.553±30.505, 19.798±11.541, 17.665±11.457, 12.103±0.124, 2.996±1.235, 0.149±0.124, and 0.082±0.047 mg kg-1, respectively). Only the Cd content has exceeded the Threshold Effect Level (TEL) at all study sites. On the other hand, the As and Cr content has not exceeded TEL at any study site. The content of Hg, Cr, Pb, Zn, and Ni has exceeded TEL only at a few study sites. The heavy metal content in estuary sites is higher than in mid-bay and mangrove sites, which can provide the information on the sources of heavy metal contaminants. There is a significant correlation for the content of Cu, As, Pb, Cd, Zn, and Ni which can indicate that the sources of these heavy metals are relatively the same (r = 0.569 to r = 0.950). The CF and Igeo values indicate that there has been contamination of several heavy metals studied. Further analysis ( ERI ) showed that the heavy metal content in the sediments poses a potentially serious ecological risk. Most of the potential ecological risks are the contribution of Cd and Hg which have high toxicity factors and this should receive special attention from local governments and stakeholders to prevent higher contamination.

Various activities such as farming, industry, household waste, fish pond, and fishery can possibly affect the estuarine and coastal ecosystem. Demak waters, located to the east of Tanjung Emas Semarang, become an influential element of fishery industry that mostly produces anchovies and shrimps. This research was aimed at (1) analyzing the spatial distribution of heavy metal Pb and Cd in the surface water and sediment; and (2) investigating the abundance of coliform in Demak waters. Moreover, in this research, water pollution index was also analyzed and compared to other polluted water areas. It was found that the Pb content ranged from 0.6037 to 0.6647 mg·1^–1 whereas the Cd content ranged from 0.064 to 0.1707 mg·1^–1. Both lead and cadmium contents had surpassed the water quality standard. The Pb content in sediment ranged from 0.563 to 0.6823 mg·kg^-1 whereas the Cd content reached 0.0047 to 0.0577 mg·kg^-1. It showed that this sediment was not polluted by Pb and Cd. The analysis of water pollution index revealed that the pollution level found in Morosari, Rejo, Tuntang, and Lohbener estuary was low. On the other hand, Wedung and Serang estuary were heavily polluted. Compared to some previous studies, most of Pb and Cd contents in Demak waters were greater. However, lead and cadmium content in sediment was lower.

Opis:

The heavy metal contamination has become a serious problem in the aquatic environment, including marine sediments. This study was aimed at analyzing the content of heavy metals in marine sediments, then assessing and evaluating the level of heavy metal contamination and its ecological risks. The sediment samples were taken using a grab sampler at six sites in the coastal waters of Mimika Regency, Indonesia. The TCLP testing method was used to determine the content of heavy metals in marine sediments. The results showed that the concentrations of Pb, Cu, Cd, and Hg in marine sediments ranged from <0.25 to 0.59 ppm, <0.02 to 0.54 ppm, <0.005 to 0.03 ppm, and < 0.0007 ppm. Only the concentrations of Cu on the Meoga and Puriri sites exceeded the quality standard in the Government Regulation of the Republic of Indonesia No. 18 year 1999. The results of the assessment of heavy metal contamination and its ecological risk potential indicate that the coastal waters of Mimika Regency are included in the category of low contamination and low ecological risks. The concentration of heavy metals in this study shows that the coastal waters of Mimika Regency are not contaminated by Pb, Cu, Cd, and Hg heavy metals.

Opis:

W pracy przedstawiono badania gleb reprezentatywnego obszaru użytkowanego rolniczo w celu oceny poziomu toksycznych metali ciężkich, które mogłyby przedostać się do upraw. Może to stanowić pierwszy krok do określenia możliwości dalszego wykorzystania gleb, zwłaszcza na obszarach, na których widoczny jest silny postęp industrializacyjny. W celu scharakteryzowania stanu gleby na dwóch głębokościach analizowano strukturę gleby, pH, gęstość objętościową oraz całkowitą zawartość ołowiu (Pb), kadmu (Cd) i niklu (Ni): TOP (próbka 0–30 cm) i BOTTOM (próbka 30–60 cm). Schemat pobierania próbek był oparty na kwadratowej siatce z 16 punktami rozmieszczonymi regularnie. Wartości stężenia metali ciężkich były poniżej prawnych limitów, ale wyższe niż regionalny poziom tła geochemicznego, co sugeruje ich pochodzenie antropogeniczne. Indeks PLI został wdrożony jako narzędzie do obliczania ogólnego stanu zanieczyszczenia metalami ciężkimi. Analiza geostatystyczna danych pokazuje zmienność przestrzenną w szczegółowej skali, zarówno w wymiarze poziomym, jak i pionowym, przy czym poziom TOP gleby wykazuje wyższe średnie stężenia Pb i Cd.
A representative sample of agricultural soil was studied for assessing the level of toxic heavy metals that could be passed on to crops; this can be the first step towards determining the possibility of its further use, especially in areas where strong industrialization progress is visible. The soil texture, pH, and bulk density along with the total amount of lead (Pb), cadmium (Cd), and nickel (Ni) were analyzed for characterizing the status of the soil at two depths: TOP (a composite sample from 0–30 cm deep) and BOTTOM (a composite sample from 30–60 cm deep). The sampling scheme was a square grid with 16 regularly spaced points. The heavy metals concentration values were below legal limits but higher than the regional geochemical background level, suggesting an anthropogenic origin. The pollution load index (PLI) was implemented as a tool for computing the generalized heavy metal pollution status. A geostatistical analysis of the data shows a spatial variation on a detailed scale, both in the horizontal and vertical dimensions, with the TOP soil showing higher average Pb and Cd concentrations.

Opis:

The content of heavy metals in peat soils of north part of Słupsk Region was low. Enrichment factors for Cd, Zn and Mn indicates on their anthropogenic origin in studied peat soils, and for Cr and Ni - natural origin. However copper may be of anthropogenic or natural origin depending on location. The farther from sea peat soils are situated the higher concentration of those metals is.
W pracy analizowano zawartość niektórych metali cieżkich (Cu, Zn, Cd, Mn, Cr, Ni) w glebach torfowych Ziemi Słupskiej (Środkowe Pomorze). Koncentracja tych metali w badanych glebach jest niewielka, niemniej jednak wyznaczone współczynniki wzbogacenia wskazują, że Cd, Zn i Mn są pochodzenia antropogenicznego, natomiast Cr i Ni - pochodzenia naturalnego. Pochodzenie miedzi było zależne od lokalizacji gleb torfowych. Im dalej od morza były usytuowane badane gleby, tym więcej zawierały analizowanych metali.

Opis:

Purpose: Water is vital for the sustenance of every life form. Urbanization, growing population and industrial development has led to exploitation of water resources globally. This study assesses quality of water resources of Mohammedia prefecture. Design/methodology/approach: The water quality analysis was carried out based on physio-chemical and heavy metal concentrations. The physio-chemical analysis comprised of status of concentration, overall quality and water pollution index evaluation. The heavy metal evaluation consisted of Ecological Risk Index, non-carcinogenic risk and carcinogenic risk assessment. Findings: The landfill near Ben Nfifikh River reported insignificant (WPI<1) – low level of pollution (>1≤1.5) for surface and groundwater points. However, the groundwater for Zenata region was found to pose both carcinogenic (CRt > 0.0001, range 0.4-35.31) and non-carcinogenic risks (HQ>1, range 6 -34) of higher degree rendering it unfit for human consumption. Hence, this study concludes that groundwater resources should not as water supply; instead, Oud El Maleh River can serve as surface water source for meeting requirements of Zenata region. Research limitations/implications: The data obtained can be categorized as landfill area near river Nfifikh and landfill area near river El Maleh. Both areas have been investigated for groundwater and surface water quality assessment. Practical implications: This study demonstrates the need to study the characteristics of groundwater (depth, flow rate, water renewal, etc.) before arranging a waste dump. This problem is especially relevant for arid countries, since residents experience a shortage of water, as well as a lack of rainfall provides a weak renewal of groundwater, which can contribute to the accumulation of a higher concentration of carcinogens in groundwater and provide a high risk to public health. If policymakers in arid countries and decision-makers have effective water quality maps, then the country can be more efficiently managed water resources without risking the population. Originality/value: The current study is planned as a multi-stage, each of which is supposed to conduct field studies of groundwater and surface water quality with appropriate parameters, analysis of institutional reports and related scientific studies in order to create an effective water quality map for rational water use.

Opis:

Surface water is subject to strong anthropogenic pressures caused by the development and the extension of the agricultural activities and also by the industrial and domestic activities. Pollution is a major environmental problem due to discharges into rivers and the excessive use of agricultural fertilizers add to that the discharges from urban and industrial sources. The aim of this study is to assess the quality and the state of the organic pollution of surface water in the Kébir wadi east, based on the Water Quality Index (WQI) and the Organic Pollution Index (OPI) during six sampling campaigns carried out between April and September of the year 2011. Seven stations were studied along the Kébir wadi east downstream from the Mexa Dam. The results are visualized by the use of GIS through making thematic maps. They revealed that half of the stations show excellent to good water quality and moderated organic pollution except the stations S3, S6 and S4, that have poor water quality and high pollution at S3 and S6 respectively, and non-potable water with very high organic pollution at S4. The anthropogenic environmental deterioration recorded in the wadi is the result of the use of nitrogen and phosphate agricultural fertilizers and especially, the discharge of untreated domestic and industrial wastewater from neighbouring agglomerations. The seasonal variation remains discrete and reflects a slight tendency to the deterioration of the waters of El Tarf region during the low waters of the summer period.

Opis:

The samples of particulate matter (PM10) were collected at five sampling sites of various character situated in the Moravian-Silesian Region (Czech Republic). Concentrations of heavy metals bound to particulate matter were determined by the method of ICP – optical emission spectroscopy. The contamination of heavy metals was expressed as the pollution load index – PLI. Human health risk assessment was performed by U.S. EPA method – using the hazard quotient – HQ, hazard index – HI, and excess lifetime cancer risk – ELCR. The pollution and resulting carcinogenic risks increase during the winter season. The potential non-carcinogenic risks are not significant.
Próbki pyłu zawieszonego (PM10) zebrano w pięciu miejscach o różnym charakterze w regionie Morawskośląskim (Republika Czeska). Stężenie metali ciężkich związanych z cząstkami stałymi oznaczano metodą ICP - optycznej spektroskopii emisyjnej. Zanieczyszczenie metalami ciężkimi zostało wyrażone jako wskaźnik obciążenia zanieczyszczeniem - PLI. Ocenę ryzyka dla zdrowia ludzkiego przeprowadzono metodą US EPA - z wykorzystaniem ilorazu zagrożenia - HQ, wskaźnika zagrożenia - HI i zwiększenia ryzyka wystąpienia raka w całym okresie życia - ELCR. Zanieczyszczenie i związane z tym ryzyko rako-twórczości zwiększa się w sezonie zimowym. Potencjalne zagrożenie nierakotwórcze nie jest znaczące.

Opis:

Thirty two active stream sediment samples were collected, panned and sieved from a 16km (500m spacing) section along Ndongo River, Buea. Sixteen of them were subjected to magnetic separation for the determination of heavy minerals under a microscope (KARL ZEISS IENA) and analyzed by XRF and AAS for As, Be, Cd, Co, Cu, Cr, Mo, Ni, Pb, Rb, Sb, Sc, Sn, Sr V, Zn, and Zr. The average element concentrations are 0.014, 64.45, 76.93, 94.52, 87.65, 147.79, 0.00, 77.00, 98.99, 40.37, 7.99, 24.70, 52.42, 1053.37, 285.46, 579.70 and 404.41ppm respectively. As (0.014 ppm) and Mo (0.001 ppm) are below l average concentrations in basalts while dispersed Be, Cd, Co, Cu, Cr, Ni, Pb, Sb, Sc, Sn, V, Zn values are mostly above tolerance limit in settlement areas and farmlands. Olivine with angular grains (1.5mm) and sub-hedral shape representing 10 vol. % is light green colored. Together with pyroxene (elongated, black colored with angular grains up to 0.7mm) are the most abundant minerals. Minor rutile with shiny luster is also present. R-mode factor analysis reveals Ni-Rb-V, Co–Cr–Pb–Zn, and Cu–Sr-Zr associations representing three geochemical entities related to agricultural (fertilizers) and settlement (domestic waste) areas. Correlation coefficients (r) vary from -0.84 (V, Sb) to 0.728 (Ni, Rb) and may indicate different sources of metal contamination. The calculated PLI (3.10 to 4.92) and Igeo (-7.37 to 9.18) of As, Be, Cd, Co, Cu, Cr, Mo, Ni, Pb, Rb, Sb, indicate metal pollution of River Ndongo sediments. The obtained classification is defined as low (As, Co, Cu, Cr, Mo, Ni, Sc, and V), partially (Co, Zn), moderately (Pb, Be) and highly to very highly (Sb, Sr, Cd) polluted. Natural and anthropogenic metal input assessment reveals that the dominantly basaltic lithologies in the area (pyroxene and olivine), the domestic and agricultural activities as well as urbanization processes of Buea are the main source of metal contamination.

Opis:

Morze Azowskie jest najmniejszym i najpłytszym morzem na świecie o małym zasoleniu. Takie właściwości powodują jego podatność na degradację pod wpływem działalności antropogenicznej. Jednym z głównych źródeł zanieczyszczeń Morza Azowskiego jest huta „Azovstal” w Mariupolu (Ukraina). Negatywny wpływ huty jest związany przede wszystkim z dużą ilością odprowadzanych do morza ścieków chłodniczych i technologicznych. W pracy przedstawiono wyniki oceny oddziaływania ścieków z huty na jakość wody morskiej i sytuację ekologiczną w strefie ich odprowadzania, dokonanej na podstawie metod stosowanych w Ukrainie oraz obowiązujących standardów jakości wód powierzchniowych. Kompleksową ocenę dokonano na podstawie wartości trzech wskaźników jakości wody morskiej – wskaźnika jakości wody (WJW), wskaźnika zanieczyszczenia wody (WZW) oraz zintegrowanego wskaźnika stanu ekologicznego (ZWSE), a także z uwzględnieniem tak zwanej zasady sumowania. Na podstawie wyników przeprowadzonej oceny wykazano, że odprowadzanie ścieków z huty „Azovstal” prowadzi do znacznego wzrostu stopnia zanieczyszczenia wód w strefie przybrzeżnej Morza Azowskiego, co stanowi zagrożenie ekosystemu morskiego i ogranicza wszystkie rodzaje użytkowania wody.
The Sea of Azov is the smallest and shallowest sea in the world with low salinity. Such properties determine its susceptibility to degradation due to anthropogenic activities. The Azovstal Iron & Steel Works in Mariupol (Ukraine) is one of the main sources of pollution of the Azov Sea. Adverse impact of the steelworks is associated primarily with the large amount of technological and cooling wastewater discharged into the sea. The paper presents the impact assessment results of wastewater discharge on the sea water quality and the ecological conditions in the discharge zone. The assessment was performed using local Ukrainian methodologies as well as applicable surface water quality standards. The comprehensive assessment was based on the three numerical integrated indicators of sea water quality: the Water Quality Index (WJW), the Water Pollution Index (WZW), the Integrated Ecological State Index (ZWSE), and the so called principle of aggregation. Based on the assessment results it was demonstrated that the wastewater discharge from the Azovstal Iron & Steel Works leads to significant increase in water pollution in the coastal zone which brings threat to the marine ecosystem and limits all types of water consumption.

Opis:

The use of phytoplankton as an indicator of water pollution is a promising tool for assessment of water quality. The purpose of this study was to determine whether diversity indices, including the species richness and diversity of phyto-plankton, could be used for reliable assessment of water quality in the Wadaslintang Reservoir in Indonesia. Surveys were conducted monthly at eight sites, from July 2019 to October 2019. Phytoplankton was collected during the day at 10:00 until approximately 15:00 in the euphotic zone. The parameters investigated were species richness and the abundance of phytoplankton, as well as water quality parameters listed in Government Regulation Number 82 of 2001. The level of pollution was represented biologically by the Shannon–Wiener diversity index and physicochemically by the STORET (storage and retrieval of water quality data) index. Moreover, the two indices were compared to determine whether a particular diversity index was more effective for assessment of this reservoir. The results showed that during the dry season, 22 taxa of phytoplankton were present, belonging to Cyanophyta, Chlorophyta, Chrysophyta, and Euglenophyta. During the wet season, 29 taxa were found, belonging to Cyanophyta, Chlorophyta, and Chrysophyta. Based on the Shannon-Wiener index and STORET index, water quality was better during the wet season than during the dry season. The results of water quality assessment using both indices were consistent, but the diversity index was a more sensitive indicator of pollution levels. Therefore, the Shannon–Wiener index is a useful tool for assessment of water quality in the Wadaslintang Reservoir.

Opis:

The major impacts on aquatic ecosystems worldwide caused by land use lead to changes in their natural conditions and limitation of water use for various needs. This paper presents the results of the study of the physical and chemical parameters and macroinvertebrate assemblage in the White Drin River (or: the Drim River, Alb. the Drini i Bardhë River) basin, the largest in Kosovo. Macroinvertebrate sampled at 11 sites in the river resulted in 5946 collected benthic organisms, which in taxonomic terms belong to 12 orders and 51 families. Of the total number of organisms, 72.28% were Insects, 25.39% Amphipoda crustaceans and 2.33% were Annelide worms and Mollusk. The used biotic indices Biological Monitoring Working Party (BMWP), Ephemeroptera, Plecoptera, and Trichoptera (EPT), average score per taxon (ASPT) and Stroud Water Research Center (SWRC) classify water quality in excellent category in the sampling site S1 near the source of the White Drin River, whereas in other sampling sites, as a result of pollution, water quality varies on category II–IV. The Pearson's correlation analyses shown that the physical and chemical parameters affect the water quality and the composition of macroinvertebrates. Our results show that the parameters that adversely affect the BMWP, EPT and ASPT biotic indices as well as the Shannon–Wiener, Mergalef and Menhinik diversity indices are: pH, electrical conductivity (EC), total suspended solids (TSS), nitrates (NO₃^–) and chlorides (Cl^–). We can conclude that the anthropogenic impact on White Drin basin affects the physical, chemical and biological parameters of the water therefore these parameters should be constantly included in Biomonitoring and Management plans for water resources in Kosovo.

Opis:

Copper is a life essential element. However, in excess it can be destructive to metabolism of microbial, plant, animal and human cells. Thus, an understanding of all conditions associated with the effect produced by copper on natural environment is vital. The purpose of the present study has been to evaluate the effect of soil contamination with copper on the activity of dehydrogenases, catalase and urease as well as to determine the tolerance of these enzymes to excessive amounts of copper in soil. The variable factors of the experiment consisted of: 1) soil type: loamy sand and sandy loam; 2) copper pollution rate in mg kg-1 d.m. of soil: 0, 150, 450; 3) soil use: unseeded and seeded soil; 4) crop species: barley, spring oilseed rape and yellow lupine; 5) dates of enzymatic analyses: 25 and 50 day. The results have revealed that copper pollution, within the rates of 150 to 450 mg kg-1 d.m. of soil, significantly inhibits the activity of dehydrogeanses, urease and catalase, with catalase being the most tolerant to excessive copper, unlike dehydrogeneases, which were the most sensitive enzymes. Urease was found to be intermediate in the response to copper. Dehydrogenases, urease and catalase are the least tolerant to the inhibitory effect of copper in soil under spring oilseed rape, being the most tolerant to the pollution in soil under oats. Copper produces stronger inhibitory effect on soil enzymes in unseeded than in seeded soil. The negative effect of excess copper in soil persists and, instead of diminishing, the longer copper remains in soil, the stronger effect it yields. Dehydrognases and catalase are less tolerant to copper in sandy loam than in loamy sand, unlike urease, which was more tolerant to the pollutant in loamy sand than in sandy loam. Tolerance of plants to soil contamination with copper is a species-specific trait. Among the tested crops, yellow lupine was the least tolerant whereas spring oilseed rape was the most tolerant to copper contamination.
Miedź jest pierwiastkiem niezbędnym do prawidłowego funkcjonowania wszystkich organizmów, jednakże jej nadmiar w środowisku może działać destrukcyjnie na metabolizm komórek drobnoustrojów, roślin i zwierząt oraz ludzi. Zatem poznanie wszystkich uwarunkowań oddziaływania miedzi na środowisko przyrodnicze jest ze wszech miar uzasadnione. Celem badań było określenie wpływu zanieczyszczenia gleby miedzią na aktywność dehydrogenaz, katalazy i ureazy oraz określenie oporności tych enzymów na nadmiar miedzi w glebie. W doświadczeniu czynnikami zmiennymi były: 1) gatunek gleby: piasek gliniasty i glina piaszczysta; 2) stopień zanieczyszczenia miedzią w mg⋅kg-1 s.m. gleby: 0, 150 , 450; 3) sposób użytkowania gleby: gleba nieobsiana i obsiana roślinami; 4) gatunek uprawianej rośliny: owies, rzepak jary i łubin żółty; 5) termin analiz enzymatycznych: 25. dzień i 50. dzień. W wyniku badań stwierdzono, że zanieczyszczenie miedzią, w zakresie od 150 mg do 450 mg·kg-1 gleby, hamuje istotnie aktywność dehydrogenaz, ureazy i katalazy. Przy czym najbardziej odporna na nadmiar miedzi jest katalaza, a najmniej dehydrogenazy. Pośrednie miejsce zajmuje ureaza. Dehydrogenazy, ureaza i katalaza są najbardziej oporne na inhibicyjne działanie miedzi w glebie pod uprawą rzepaku jarego, a najmniej pod uprawą owsa. Miedź silniej hamuje aktywność enzymów w glebie nieobsianej roślinami niż w glebie obsianej. Negatywne działanie nadmiaru tego pierwiastka w glebie ma charakter trwały i zamiast ustępować nasila się wraz z czasem jego zalegania w glebie. Dehydrogenazy i katalaza są bardziej oporne na działanie miedzi w glinie piaszczystej niż w piasku gliniastym, a ureaza odwrotnie – bardziej oporna w piasku gliniastym niż w glinie piaszczystej. Wrażliwość roślin na zanieczyszczenie miedzią jest cechą gatunkową. Spośród badanych roślin najbardziej wrażliwy jest łubin żółty, a najmniej rzepak jary.

Opis:

Objectives The objective of this study was to present a technique for estimating the effect of ambient air pollution mix on health outcomes. Material and Methods We created a technique of indexing air pollution mix as a cause of the increased odds of health problems. As an illustrative example, we analyzed the impact of pollution on the frequency of emergency department (ED) visits due to colitis among young patients (age < 15 years, N = 11 110). Our technique involves 2 steps. First, we considered 6 ambient air pollutants (carbon monoxide, nitrogen dioxide, sulphur dioxide, ozone, and 2 measures of particulate matter) treating each pollutant as a single exposure. Odds ratios (ORs) for ED visits associated with a standard increase (interquartile range – IQR) in the pollutants levels were calculated using the case-crossover technique. The ORs and their 95% confidence intervals (95% CIs) were also found for lagged exposures (for lags 1–9 days). Second, we defined a Health Air Study Index (HASI) to represent the combined impact of the 6 air pollutants. Results We obtained positive and statistically significant results for individual air pollutants and among them the following estimations: OR = 1.06 (95% CI: 1.02–1.1, NO₂ lag 3, IQR = 12.8 ppb), OR = 1.04 (95% CI: 1.01–1.07, SO₂ lag 4, IQR = 2.3 ppb), OR = 1.04 (95% CI: 1–1.06, PM lag 3, IQR = 6.2 μg/m³). Among the re-calculated ORs with the HASI values as an exposure, the highest estimated value was OR = 1.37 (95% CI: 1.12–1.68, for 1 unit of the HASI, lag 3). Conclusions The proposed index (HASI) allows to confirm the pattern of associations for lags obtained for individual air pollutants. In the presented example the used index (HASI) indicates the strongest relation with the exposure lagged by 3 days.

Opis:

This study focuses on the influence of motor transport on various indicators of park ecosystems and Taraxacum officinale Web., as well as on their applicability to the bioindication of the urban environments in the largest megalopolis of Ukraine, namely, Kyiv. Our investigations were carried out in 14 park ecosystems exposed to different levels of aerotechnogenic loading: low pollution level in Pushcha-Vodytsya (park) and outskirts, average pollution level alongseven roads with medium traffic and high pollution level along eight highways. Pollen indication, integration and statistical methods were used to identify the most sensitive indicators of the impact of air pollutants. The aim is to assess the impact of vehicle emissions on the state of park ecosystems in the metropolis using bioindication and GIS technologies. The effects of air pollution on green infrastructure at the level of cells, organisms, groups and ecosystems in time and space are revealed. Under the influence of aerotechnogenic pollution, there is a deterioration of trees, their drying, defoliation of crowns and deterioration of integral indicators of park ecosystems. Using QGIS (Free open source geographic information system, version 3.12.3 „București”, May 15, 2020), we have created maps for the spread of air pollutants. The highest levels of air pollution and damage to parks were concentrated in the central part of the city with dense buildings and near heavy traffic roads. The average daily maximum allowable concentration (MAC) of phytotoxicants exceeded 1.5 MACa.d. and depended on the terrain and directions of the prevailing winds. We registered degradation of the megalopolis ecological state by 19.3% for 7 years.

Opis:

In the study suitability of water quality index approach and environmetric methods in fi ngerprinting heavy metal pollution as well as comparison of spatial variability of multiple contaminants in surface water were assessed in the case of The Gediz River Basin, Turkey. Water quality variables were categorized into two classes using factor and cluster analysis. Furthermore, soil contamination index was adapted to water pollution index and used to fi nd out the relative relationship between the reference standards and the current situation of heavy metal contamination in water. Results revealed that surface water heavy metal content was mainly governed by metal processing, textile and tannery industries in the region. On the other hand, metal processing industry discharges mainly degraded quality of water in Kemalpasa and Menemen. Furthermore, Kemalpasa region has been heavily affected from tannery and textile industries effl uents. Moreover, pollution parameters have not been infl uenced by changes in physical factors (discharge and temperature). This study indicated the effectiveness of water quality index approach and statistical tools in fi ngerprinting of pollution and comparative assessment of water quality. Both methods can assist decision makers to determine priorities in management practices.

Opis:

Air quality is closely related to people’s health and life. In addition to being directly affected by social activities and atmospheric emissions, the impacts of meteorological factors are also significant. Based on daily Air Quality Index (AQI) data and various meteorological parameters in the Yangtze River Delta (YRD), this paper summarized the spatiotemporal evolution characteristics of AQI over YRD, and quantitatively analyzed the contribution of different meteorological elements to air quality. We also evaluated different spatial interpolation methods to produce surface distribution of AQI, and noted that the Ordinary Kriging outperformed other methods. The spatial distribution of AQI in YRD showed seasonal and annual variations. However, the days with AQI over 100 (level ii) were mostly observed in winter. Generally, more severe air pollution was observed in the northern part of YRD than in the southern ones, for example the air quality of the Ningbo metropolitan area was the best, while in Hefei it was the worst. It was found that meteorological parameters have spatially varying effects on AQI. For instance, pressure has a significant positive effect on AQI, and others showed negative correlations. We also predicted AQI by exploiting different machine learning-based models. Through model comparison, it was found that the Autoregressive Integrated Moving Average Model – ARIMA (0,1,2) has higher prediction accuracy for AQI than Multiple Linear Regression (MLR). The findings of this research can be used in future forecasting of air pollution, and also in air pollution controlling programs.

The monitoring of the environmental components condition, exposed to the influence of the cement production enterprises, was the aim of the conducted research. One of the largest cement production factories in Russia, where the territory of negative impact has a total area of over 300 square kilometers, was the object of the study. The observations of the dust content in atmospheric air, as well as the determination of degradation degree of vegetation in the area of influence of the considered production facility were conducted. Chemical and granulometric composition of the cement dust, which is emitted in atmospheric air, were identified in the laboratory. Mapping model, which indicates the complex ecological welfare of the territory, exposed to the cement production industry, was compiled by the authors on the basis of the data, obtained in conducted research. The mapping model takes into account both the content of dust in near-ground atmosphere, and the extent of its deposition to soil, vegetation and surface water bodies.

Opis:

This assessment of the environmental degradation by toxic chemical elements within the Upper Silesian Industrial Agglomeration of Poland encompasses the impact of mining for base metals and coal and non-ferrous metalurgy, as well as the discharge of industrial and municipal sewage causing strong degradation of the natural environment in the area over the years. The content of the following elements: Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Mo, Ni, P, Pb, S, Sn, Sr, Ti, V and Zn has been assessed both in the topsoil (0.0-0.3 m) and the subsoil (0.8-1.0 m) of the study area. Concentrations of the elements in the <2 mm soil fraction were analysed using the ICP-OES method after Aqua regia extraction. The soil contamination was assessed based on the enrichment factor (EF) and geo-accumulation index (Igeo). The tests revealed elevated contents of several metals, arsenic and sulphur, exceeding the regional geochemical background levels. Unusually high concentrations of the following elements: As (up to 5,300 mg/kg), Cd (up to 388.8 mg/kg), Cr (up to 1,638 mg/kg), Cu (up to 13,230 mg/kg), Hg (up to 23.44 mg/kg), Mo (up to 93.7 mg/kg), Pb (up to 54,940 mg/kg), Sn (up to 701 mg/kg) and Zn (up to 88,120 mg/kg) were recorded. The highest concentrations of these elements were found in the proximity of smelters and residential areas. The spatial distribution of metals is shown as interpolated data on maps and compared with the locations of mining and industrial sites.

Opis:

Toxic waste, soil, and ash samples were collected in the landfill (solid environmental hot spots) near the Trepça complex, New Co Ferronickeli, and Kosovo thermal power plants. They were analyzed by the ICP-OES method to measure the concentration of some toxic metals. The pollutant with the highest mean concentration (in an acidic medium) was Fe (36 400.0), followed by Mn (8683.0), Cr (6575.0), As (4739.0), Pb (3364.0), Zn (2394.0), Ni (922.6), Cu (297.6), Co (46.6), and Cd (61.8) (all concentrations in mg/kg). Three pollution indices were used such as the geoaccumulation index (Igeo), contamination factor (CFi), and pollution load index (PLI). The CFi values determined for Fe, Mn, Cr, As, Pb, Zn, Ni, Cu, Co, and Cd indicated high contamination. In all soil samples, the PLI values showed the presence of soil pollution.

Opis:

W pracy zastosowano wybrane systemy biotyczne do oceny jakości wody w stawach infiltracyjnych na terenach wodonośnych we Wrocławiu oraz w graniczącym z nimi starorzeczu Oławy. Wykorzystane indeksy biotyczne opierają się na zoobentosie, którego skład gatunkowy ulega zmianie wraz ze wzrastającym zanieczyszczeniem środowiska wodnego. Jakość wody powierzchniowej została oceniona z zastosowaniem systemów biotycznych BMWP-PL, ASPT-PL, FBI, EPT, BBI, TBI i CBS. Otrzymane wyniki porównano między sobą oraz z wybranymi wskaźnikami fizyczno-chemicznymi wody, co umożliwiło ocenę przydatności analizowanych systemów biotycznych. Oceniono także bioróżnorodność wody na badanym obszarze. W tym celu obliczono dominację oraz frekwencję poszczególnych gatunków i rodzin na stanowiskach badawczych oraz obliczono wartości wskaźników bioróżnorodności Hurlberta i Margalefa. Zarówno wskaźniki fizyczno-chemiczne, jak i biologiczne potwierdziły ogólnie złą jakość wody na terenach wodonośnych. Nawet na stanowiskach o dużej bioróżnorodności stwierdzono występowanie gatunków pospolitych, stosunkowo odpornych na zanieczyszczenia. Woda we wszystkich badanych stawach została sklasyfikowana jako jedynie zadowalającej, a w niektórych przypadkach nawet niezadowalającej jakości. Uzyskane wyniki potwierdziły zasadność stosowania systemu biotycznego BMWP-PL na szerszą skalę w Polsce.
For the purpose of this study, seven biotic systems were chosen to assess the quality of wet pond water within the aquifer of Wroclaw and in the bordering old Olawa river basin: BMWP-PL, ASPT, BBI, FBI, TBI, CBS and EPT. They all entail zoobenthic communities, whose composition changes with increasing pollution of the aquatic environment. The results obtained were compared with the values of some physicochemical parameters of the water, which enabled the applicability of the biotic systems to be evaluated. The water within the area under study was also analyzed for biodiversity. For this purpose calculations were performed to determine the domination and frequency of particular species and families at the sampling sites, as well as to establish the values of the Hurlbert and Margalef biodiversity indices. Both physicochemical and biological parameters make it clear that water quality in the area of the aquiferous layers is generally poor: species of comparatively high resistance to water pollutants were found to occur even at sampling sites characterized by great biodiversity. Water quality in all of the wet ponds examined has been classified either as acceptable or in some instances even as unacceptable. The results obtained support the applicability of the BMWP-PL index and recommend its use on a larger scale in Poland.

Opis:

Should an oil spill of tier III magnitude occur in the Northern Adriatic, there is a high probability that the oil will reach and pollute the surrounding coastline. Therefore, it is vital to conduct coastal vulnerability studies to develop priority plans and coastal vulnerability maps to help first responders protect the coastline. As there is no common contingency plan for oil spills in the Northern Adriatic, three countries, Italy, Slovenia, and Croatia, which share the area, decided to participate in the North Adriatic Incident Response System (NAMIRS) project. Part of the project was to conduct a coastal vulnerability study in the area. One of the three pillars for determining vulnerability, in addition to the ecological and geomorphological factors, is the socioeconomic aspect, which was studied as part of the research. As there are no clear scientific methods to determine the vulnerability of the socio‐economic factors, a survey was conducted where the participants gave their subjective opinion on its value. This was done through three workshops organised in each participating country, where professional stakeholders familiar with the state of socio‐economic activities assessed their vulnerability. The values obtained were combined with the assessments of the geomorphological and environmental factors and gathered in a coastal vulnerability layer, which was incorporated into a GIS as a standard coastal vulnerability map that will help first responders prioritise coastal protection. The research results will also be useful globally and not just in the area studied by NAMIRS, since the method used is readily applicable to any part of the world.

Opis:

A novel infectious corona virus disease (COVID-19) was identified in the month of December 2019. It has now been announced as a worldwide pandemic by the World Health Organization. COVID-19 pandemic has positive impacts on the environmental pollutants. In present work, Coalfield areas of Jharia Coalfields (JCF), India have been taken as a case study to evaluate the effect of the lockdown on air quality at 10 locations. This study had been selected to estimate the reduction in concentration of pollutants likePM10, PM2.5, SO2, and NOx during 3 Seasons (summer, Post-Monsoon and winter season) in the year 2019 in comparison to the concentration during the lockdown period i.e. from April 2020 to June 2020. The study areas selected was as fire affected and non-fire affected areas of Jharia Coalfield to identify the contribution of pollutants in the mining area to establish the baseline concentration of Business as usual (BAU) vs. the lockdown condition. The average reduction in concentration of PM10, PM2.5, SO2 and NOx was observed as 18%, 14%, 22% and 26% respectively during the lockdown period in comparison with the annual average concentration. As observed, the AQI value at the selected monitoring sites in JCF was 1.5 times higher in comparison to the lockdown period. This study will provide the confidence to the regulatory body for strict implementation of the applicable air quality standard/policies in the mining areas. The study will also provide confidence to the regulatory body in making emission control strategies for improvement of environmental conditions and human health.

Opis:

The Oued Souf free aquifer located in the South East of Algeria represents the main water resource used mostly for urban and agricultural activities. The intensive use of chemical fertilizers has led to serious environmental problems such as contamination of the free aquifer in the region. Thus, aquifer vulnerability has been assessed using several different methods (DRASTIC, GOD, and the Susceptibility Index ‘SI’) based on a geographic information system (GIS). For each method, two vulnerability maps have been developed in the years 2002 and 2012. These maps show that the study area is more exposed to urban, and especially agricultural, pollution. Two classes of vulnerability (moderate and high) have been identified by both DRASTIC and GOD methods. A combined analysis reveals that the moderate class showing 48% (for the GOD method), and the high class showing 57% (for the DRASTIC method) are the most dominant. However, the Susceptibility Index method (SI) revealed that the vulnerability varies from moderate to very high-level classes. In 2012, about of 53% of the study area was dominated by moderate vulnerability classes. The high vulnerability class also includes a considerable part of the land (41%) around urban or strongly agricultural areas, while only 6% is under very high vulnerability groundwater contamination. In addition, a marked decrease in the vulnerability level was noticed in 2012 compared to 2002. This decrease is mainly due to the lowering of the water table after the installation of a vertical drainage network to evacuate the surplus water to the depression and Chotts areas in the North of the region. These results provide a guide for decision-makers involved in the protection of groundwater pollution in such a vulnerable area.

Opis:

Ditlenek siarki jest jednym ze wskaźnikowych gazów, które decydują o jakości powietrza atmosferycznego, zwłaszcza na obszarach aglomeracji miejskich. Pochodzi on zarówno z emisji przemysłowej, jak i ze źródeł lokalnych (tzw. niskiej emisji). Celem pracy była analiza rozkładu przestrzennego ditlenku siarki na obszarze Bielska-Białej oraz opracowanie mapy jakości powietrza z uwzględnieniem indeksu jakości powietrza dla badanego polutanta. W pracy wykorzystano materiały z przeprowadzonych w 2012 r. badań własnych, zrealizowanych w oparciu o japońską metodę Amaya-Sugiura w modyfikacji Krochmala. Materiał badawczy pochodził z ekspozycji próbników pasywnych na 30-50 stanowiskach pomiarowych, rozmieszczonych z uwzględnieniem zróżnicowanej topografii oraz form zagospodarowania terenu w granicach administracyjnych gminy Bielsko-Biała. Na podstawie miesięcznych stężeń ditlenku siarki, wahających się od 5 μg/m3 na obszarach pozamiejskich do 20 μg/m3 w centrum miasta, oraz przyjętych klas indeksu jakości powietrza opracowano mapę bonitacyjną sytuacji aerosanitarnej.
Sulphur dioxide is one of the indicator gases that affect the air quality, especially in urban areas. It comes mostly from industrial emissions as well as from local sources (so-called low emission). The aim of this study was to analyze the spatial distribution of sulfur dioxide in Bielsko-Biala area and to develop maps of the air quality taking into account the air quality index for the pollutant tested. The paper includes test results obtained by means of a Japanese method (the Amaya-Sugiura’s method) modified by Krochmal. The research material came from the exposure of passive samplers located in 30-40 measuring stands in administrative boundary of Bielsko-Biala. The samplers were distributed taking into account a diversity of topography and a land development plan. On the basis of month concentrations of sulfur dioxide ranging from 5 μg/m3 in non-urban areas to 20 μg/m3 in the city center and accepted classes of the air quality index, a bonitation map of air quality situation was made.

Opis:

The paper deals with sediments of anthropogenic reservoirs from the central part of the Katowice Upland. Over most of the area, the original relief was considerably altered due to many-years’ mining of hard coal, historical mining and processing of zinc-lead ores, smelting of iron and non-ferrous metals, and chemical and machinery industries. The changes in land surface give rise to mining collapse areas transformed to water reservoirs. Sediment samples (103 samples in total) were collected form artificial lakes, ponds and settling ponds. Samples were air-dried, sieved through a 0.2-mm nylon sieve and digested in aqua regia. Contents ofAg, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, P Pb, S, Sn, Sr, Ti, Vand Zn in the samples were determined by the ICP-OES method. Mercury content was measured using the CV-AAS method. To assess the extent of sediment contamination the Index of Geoaccumulation (Igeo) and the ecotoxicological (Threshold Effect Concentration and Probable Effect Concentration) criterion were used. The sediments show very different chemical compositions. The content of trace elements varies from values lower than the regional geochemical background of the Silesian-Cracow region to extremely high concentrations. Distribution of many toxic chemical elements is characterized by high spatial variability and a strong dependence on the location of pollution sources. About 60% of analysed samples were heavily contaminated due to the very high concentration of cadmium (up to 905.9 mg/kg), lead (up to 25,081 mg/kg) and zinc (up to 45,361 mg/kg) as well as arsenic (up to 2,220 mg/kg), chromium (up to 901 mg/kg) and mercury (up to 11.80 mg/kg). Due to the concentration of metals (TEC and PEC values) almost 80% of the sediments can be harmful to aquatic organisms, as well as to wild animals that consume them. The main cause of harm is the very high concentrations of cadmium, lead and zinc, less of silver, arsenic, chromium, copper and nickel.
