Opis:
The protection and preservation of good groundwater quality is of critical importance worldwide, nowadays. Increasing urbanization, economic development and agricultural activities, combined with limited precipitation contribute to the quantitative and qualitative degradation of groundwater resources, especially in the eastern Mediterranean region. For this purpose, a series of actions are implemented including groundwater vulnerability mapping that can depict prone to pollution aquifers which need protection and/or restoration measures. In this study, the efficiency of two well-known methodologies (COP and DRASTIC) for groundwater vulnerability and pollution risk mapping was assessed in the Sperchios river basin. The vulnerability and pollution risk maps of the two methodologies were spatially compared to each other and the observed similarities and differences were discussed and explained. The output of the study shows that in the particular geoenvironmental conditions DRASTIC method performs better than the COP, particularly in the lowland, porous media aquifer.

Opis:
The Mio-plio-quaternary aquifer of the Djelfa Syncline is part of a region in Algeria which is characterized by the lack of surface water resources and located in a semi-arid climate. Since alluvial aquifers, and among them our aquifer, are the most vulnerable because of thier direct exposure to the pollution caused by the infiltrated pollutants, this work focused on the assessement of groundwater pollution vulnerability, hazard and risk. Thus, several methods were used; for this purpose, such as the DRASTIC and WQI methods mapped using a GIS. The results obtained clearly show a low to moderate vulnerability. The DRASTIC model and its validation based on the correlation with WQI revealed a low correlation ($WQ_I$vs $D_I$ : 0.221). Since the vulnerability model does not match with the groundwater quality, pollution risk was assessed by combining vulnerabilty and hazard (i.e, water quality). The risk map illustrated three levels ranging from low to high risk. This map should be helpful in decision making and groundwater management through avoiding high risk areas.

Opis:
The purpose of this research was to determine the groundwater intrinsic vulnerability to pollution of shallow groundwater in Wielkopolska Province, Poland and to assess the risk of pollution by nitrates. Wielkopolska is known as an area where the problem of water pollution by nitrates has existed for a long time due to intensive agriculture. DRASTIC method and its optimized version as well as four other risk evaluation methods were selected to assess the risk pollution with nitrates. The results of either method did not correlate with nitrate concentrations recorded in the total of 1679 groundwater monitoring points. Therefore a new method of groundwater pollution risk assessment (NV-L) was proposed. The new method is based on optimized results of the DRASTIC system and the L parameter which considers not only land use types, but also the amount of nitrogen loading leached from soil as a result of fertilizer consumption, and from wet deposition. The final results of NV-L method showed that the largest part of the study area is covered by a very low class of pollution risk (30.6%). The high and very high classes occupy 11.6% of the area, mostly in the areas designated until 2012 as the Nitrate Vulnerable Zones. Validation of the results of all methods showed that the other methods than NV-L cannot be used as a basis for reliable assessment of the risk of groundwater pollution by nitrates, as they do not take into account the nitrogen load leached from the soil profile.
Celem badań było określenie podatności wód podziemnych na zanieczyszczenie płytkich wód podziemnych w województwie wielkopolskim oraz ocena ryzyka zanieczyszczenia azotanami. Województwo wielkopolskie uważane jest za obszar, na którym od dawna znany jest problem zanieczyszczenia wód azotanami z powodu intensywnego rolnictwa. Do obliczenia indeksu podatności naturalnej wybrano metodę DRASTIC i jej zoptymalizowaną wersję, natomiast do oceny ryzyka zanieczyszczenia azotanami cztery metody będące modyfikacjami metody DRASTIC. Wynik żadnej z nich nie był skorelowany ze stężeniami azotanów odnotowanymi w 1679 punktach monitoringu wód podziemnych, dlatego zaproponowano nową metodę oceny zagrożenia wód podziemnych NV-L. Metoda opiera się na zoptymalizowanych wynikach systemu DRASTIC i parametrze L, który uwzględnia nie tylko typ użytkowania gruntów, ale także wielkość ładunku azotu, pochodzącego z wymywania z gleby nawozów mineralnych i organicznych oraz z mokrej depozycji w opadach. Wyniki metody NV-L wykazały, że największy obszar objęty jest bardzo niską klasą zagrożenia zanieczyszczeniami (30,6%). Klasa wysoka i bardzo wysoka zajmują 11,6% powierzchni, głównie na obszarach wyznaczanych do 2012 roku jako obszary szczególnie narażone na wymywanie azotu do wód powierzchniowych. Wyniki wskazują, że w procedurach zastosowanych metod oceny podatności brakowało pewnych ważnych informacji. Dlatego ich wyniki należy traktować jako szacunkowe i nie mogą one być wykorzystywane w dalszych analizach jako użyteczne narzędzie ochrony wód podziemnych. Uwzględnienie innych, nowych elementów do oceny podatności wód podziemnych lub ryzyka zanieczyszczenia, może okazać się kluczowym czynnikiem, jak miało to miejsce w przypadku metody NV-L i wykorzystania danych dotyczących ładunku azotu wymywanego z profilu glebowego.

Introduction. Population increasingly draws attention to the issues concerning the environment degraded by the progress of civilization and the impact of this process on health. However, public awareness of the risk exposure to indoor contaminants is lagging a long way behind knowledge regarding outdoor environmental hazards. The aim of the study was to assess the risk perception related to exposure to indoor environmental factors in the population of Silesia. Materials and methods. In this study the electronic version of a questionnaire survey – downloaded on the website www.moja-ankiety.pl. was used. During the 3-months duration of the project 552 subjects participated in the survey. In the study participated the Silesian Voivodeship inhabitants such as chat rooms users, newsgroups and online forum participants. Data analysis was performed by using statistical program – STATA Version 8 SE [9], where the Kruskall-Wallis test and χ 2 test were applied. Statistical significance was assessed at p value *0.05. Results. Despite the low perception of environmental health hazards inside the dwellings, the majority of respondents were able to indentify health effects and ways to reduce exposure to indoor air pollution. Both gender, place of residence, education level and age significantly affected the level of perception of respondents on the risk connected with exposure to indoor air pollution. Conclusion. It is necessary to continuously work on raising public awareness of environmental health hazards in confined spaces, the causes of their occurrence, types, effects and above all the ways to counter these threats.
Wstęp. Populacja mieszkańców zwraca coraz większą uwagę na kwestie związane z degradacją środowiska w wyniku postępu cywilizacyjnego i skutku tego procesu na zdrowie. Jakkolwiek ich świadomość narażenia na zanieczyszczenia wnętrz jest znacznie mniej zaawansowana w stosunku do zagrożeń środowiskowych z zewnątrz. Celem tego badania była ocena ryzyka związanego z narażeniem na czynniki środowiskowe wnętrz u mieszkańców województwa śląskiego. Materiały i metody. W tym badaniu zastosowano ankietę w wersji elektronicznej umieszczonej na stronie internetowej www.moja-ankiety.pl. W czasie trzymiesięcznych badań udział wzięło 552 uczestników, mieszkańców województwa śląskiego takich jak: użytkownicy czatów, grup dyskusyjnych i forów internetowych. Analiza danych była przeprowadzona przy użyciu programu statystycznego STATA Version 8 SE [9], gdzie zastosowano testy Kruskall-Wallis i χ 2. Istotność statystyczna była oceniona na poziomie wartości p*0,05. Wyniki. Pomimo niskiej percepcji odnośnie zdrowotnych zagrożeń środowiskowych wewnątrz pomieszczeń, większość respondentów była w stanie ocenić skutki zdrowotne i sposoby ograniczenia narażenia na zanieczyszczenia powietrza wnętrz. Zarówno płeć, miejsce zamieszkania, poziom wykształcenia jak i wiek wywierały znaczny wpływ na poziom percepcji respondentów co do ryzyka związanego z narażeniem na zanieczyszczenie powietrza wewnątrz. Wnioski. Koniecznym jest stałe podnoszenie społecznej świadomości dotyczącej środowiskowych zagrożeń zdrowia w pomieszczeniach zamkniętych, przyczyn ich powstawania, rodzajów, skutków i przede wszystkim sposobów zwalczania tych zagrożeń.

Opis:
The intrinsic vulnerability of groundwater aquifers refers to their sensitivity to all contamination coming from soil surface irrespective of the nature of the polluting. In order to improve the protection of groundwater, there must be a reduction in the infiltration of contaminants towards the reservoir through the impacting factors determination of this phenomenon by means of research. There are collected models that include particular number of factors which allow the determination of a sign of groundwater vulnerability of all superficial pollutions. The goal of the study centers on ascertaining the state of vulnerability and the risk of groundwater pollution of the Collo region with a new proposed method by Kherici. Generally, assessment methods of vulnerability and the danger of groundwater pollution employ parametric systems with numerical quotation, cartographic superposition where the analytical methods are based on equations. In this study, we consider the combination of criteria dependent on natural factors (thickness of the unsaturated zone, geologic facies, degree of auto-purification) and the causes of groundwater vulnerability to man-made pollution (anthropogenic factors).
Podatność podziemnych poziomów wodonośnych odnosi się do ich wrażliwości na zanieczyszczenia pochodzące z powierzchni gleby, niezależnie od ich charakteru. Dla ochrony wód gruntowych konieczne jest ograniczenie infiltracji zanieczyszczeń po ustaleniu czynników wpływu metodami badawczymi. Istnieją modele obejmujące szereg czynników, które umożliwiają określenie podatności wód gruntowych na zanieczyszczenia powierzchniowe. Celem badań było określenie stanu podatności i ryzyka zanieczyszczenia wód gruntowych w regionie Collo za pomocą nowej metody zaproponowanej przez Kherici. W metodach oceny podatności i zagrożenia zanieczyszczeniem wód gruntowych stosowane są zwykle parametryczny system numeryczny i kartograficzne nałożenia, w których metody analityczne bazują na równaniach. W pracy rozważano kombinację kryteriów zależnych od czynników naturalnych (miąższość strefy nienasyconej, facje geologiczne i stopień samooczyszczenia) oraz przyczyny podatności wód gruntowych na zanieczyszczenia antropogeniczne.

Municipal refuse may increase heavy metal concentration in soil, even at low levels, and their resulting long-term cumulative health effects are among the leading health concerns all over the world. In this study, we investigated the concentration of heavy metals in soils and edible plant leaves grown in an abandoned dumpsite along Akachi road in Owerri municipality. The soil samples were collected at each plot using a soil auger at the depth of 0-10 cm. Leaves of dominant edible plant species were selected and collected from each sample plot. The samples were dried in an oven with forced air at 40 °C, milled to fine powder then digested with 10 ml concentrated HNO3 and 5 ml concentrated HClO4 and were analyzed for Cr, Cu, Fe, Mn, Al, and Zn, using an H183200 MultiParameter Bench Photometer. Result showed that metals in in the sampled soils included (in order of quantity) Cr: 150-280 >Fe: 116.50-203 >Cu: 12.4-18.8 >Mn: 0-20 >Al: 0.08-0.16 >Zn: 0-1.4 mg kg-1 Dw. Moreover, levels of metals in the edible plant leaves are in the order of: Zn>Fe>Cu>Al>Mn>Cr. Zn, in particular, was higher than FAO/WHO recommended limits. Still, application of Pollution Load Index and Ecological risk models showed that the area is unpolluted and safe for use. Daily Metal Intake estimates indicated that zinc is mostly consumed from the plant species. The trends in Transfer Factor for the heavy metal in vegetable samples studied were in order: Zn>Al>Cu>Mn>Fe>Cr. Therefore, abandoned solid waste dumpsites contained significant concentrations of heavy metals which are later absorbed and accumulated by plants growing it.

The paper presents the overall risk management state for the crude oil tanker fleet, evidenced by EMSA and other international marine organisations. Based on historical statistical data related to fleet size, accident reports, amount of oil spilled on the sea and the economic value of the crude oil transport business, the risk acceptance criteria are evaluated. The Formal Safety Assessment is further used for a systematic assessment of risk, where potential hazards are analysed with structured methods (HAZID) and represented in event trees. The paper studies three risks: PLL (potential loss of lives), PLC (potential loss of containment) and PLP (potential loss of property). A general approach is presented and discussed with a particular focus on the evolution of risk acceptance in recent decades and evaluations of risk F-N curves for different tanker sizes.

Opis:
Nieświadomi konsekwencji przebywania w pomieszczeniach zamkniętych, uważamy je za w pełni bezpieczne, gdyż chronią nas one przed negatywnymi skutkami środowiska takimi, jak zmienność klimatu (temperatura, opady, wiatr). Pracujemy i przebywamy w pomieszczeniach zamkniętych, pokojach, szkołach, przedszkolach, uczelniach i innych miejscach spędzając w nich około 80-90% naszego życia codziennego. Mimo to raczej nie zdajemy sobie sprawy z nagromadzenia szkodliwych substancji organicznych i nieorganicznych zawartych w materiałach budowlanych i wykończeniowych oraz instalacjach. Narażenie na te substancje często powoduje choroby dróg oddechowych, czy skóry, a nawet choroby nowotworowe. Równie niebezpieczne są organizmy żywe; mikroorganizmy, roztocza i grzyby, odchody niektórych owadów, związki chemiczne (organiczne i nieorganiczne), cząsteczki kurzu oraz mikroaerozole. Można znacznie obniżyć ryzyko narażenia na te czynniki poprzez włączenie do współpracy firm odpowiedzialnych za prace budowlane, instalatorskie oraz wykończeniowe, jak również poprzez szeroko rozumiane utrzymywanie czystości w pomieszczeniach zamkniętych. Rozwiązanie problemu ryzyka w pomieszczeniach zamkniętych będzie znacznie łatwiejsze przy odpowiedniej edukacji społeczeństwa w tym zakresie.
Unaware of the consequences of dwelling in the interiors we consider them the safest place as they protect us from negative factors of external environment including the variability of climate (temperature, precipitations and wind). Time spent in the interiors, rooms, kindergartens, schools, universities and other places that we work in amounts to 80-90 % of our everyday life. Despite that fact we are usually unaware of the accumulation of toxicorganic and inorganic substances contained in construction, finishing and installation materials and stocks. Exposure to the mentioned factors is a frequent cause of respiratory tract and skin diseasesand even the cancer. Equally dangerous are living organisms, microbes, actinomycetes and fungi, excrements of some insect speciesas well as chemical compounds (organic and inorganic), particles of dust and microaerosoles. The threats could be reduced at a more intensive cooperation of construction, installatory and finishing in stitutions as well as a proper exploitation and keeping of cleanness in the interiors. Solving the risk issue would be much easier if the public were more educated in the ecology of interiors.

Opis:
Surface sediment quality of potential rivers in Peru was evaluated using indicators of contamination, accumulation and ecological risk of heavy metals and As. Surface sediment samples were collected at 54 sampling sites in the Tishgo and Chia rivers during 2018. The determination of Cu, Pb, Zn and As was performed by flame atomic absorption spectrophotometry. The results revealed the decreasing order of the mean concentrations of heavy metals and As in the Chia River of Zn > Cu > As > Pb and Tishgo of Zn > Pb > As > Cu. The PLI for the Tishgo River were greater than one (PLI > 1) denoting the deterioration it has been experiencing. In the Chia River, 60% of the sampling sites indicated no appreciable contamination by these elements (PLI < 1). The Igeo values of As in both rivers showed a state of contamination, from moderately to severely contaminated. In the Tishgo River the potential ecological risk varied from low to moderate and in the Chia River from low to considerable. Finally, this study reveals the applicability of the evaluation indexes of contamination, accumulation and potential ecological risk of toxic metals so that special control measures can be adopted.

Objectives: There are few studies about the association between breathing polluted air and increased risk of cardiovascular diseases and cardiac death in the Middle East. This study aimed to investigate the relation between air pollutants and cardiovascular mortality (based on ICD-10) in Ahvaz. Material and methods: In this ecological study, the data about cardiovascular disease mortality and air pollutants from March 2008 until March 2015 was inquired from the Ahvaz City Authority and the Khuzestan Province Environmental Protection Agency. The quasi-Poisson, second degree polynomial constrained, distributed lag model; using single and cumulative lag structures, adjusted by trend, seasonality, temperature, relative humidity, weekdays and holidays was used for the data analysis purposes. Results: Findings indicated a direct significant relation between an interquartile range (IQR) increase in ozone and cardiovascular deaths among men after 3 days’ lag. There was also a significant relation between an IQR increase in particulate matter below 10 μm and cardiovascular deaths for all people, over 60 years old and under 18 years old after 3 and 13 days’ lags. There was a significant relation between an IQR increase in nitrogen dioxide and carbon monoxide, and cardiovascular deaths in the case of under 18-year-olds (in the lag 11) and over 60-year-olds (in the lag 9), respectively. We finally found a significant association between an IQR increase in sulfur dioxide and cardiovascular deaths in the case of men, under 18-year-olds and from 18- to 60-year-olds in the lag 9, 0, and 11, respectively (p-values < 0.05). Conclusions: It appears that air pollution is significantly associated with cardiovascular deaths in Ahvaz City. Int J Occup Med Environ Health 2018;31(4):459–473

Opis:
Poor air quality can pose severe risks to human health and can also influence negatively on the natural environment. Annaba suffers from air pollution due to the industrial activities occurring in the province including, electricity generation, waste incineration, chemistry and other small additional industrial operations. However, mining, steel industry and metallurgy are considered among the most polluting activities. The aim of our research is to assess the risks of air pollution emissions with NO2, SO2, Toluene and Benzene as a result of industrial enterprises activities in Annaba province. The application of geo-graphical information system (GIS) mapping based on automatic monitoring networks of air quality, allows us the assessment of air pollution risks in the studied area. Two zones of air pollution with N02 in the level of 1 MPC has been recorded near the blast furnaces and the steel shop, the second halo of NO2 pollution was fixed over residential infrastructures. Moreover, revealed a tendency to higher content of nitrogen dioxide in the atmosphere of the bigger part of Annaba region. Corresponding to the data obtained from stationary monitoring networks, the annual average concentration of SO2 was significantly lower than the MPC. Based on GIS maps there are two areas with SO2 pollution inside the territory of El Hadjar metallurgical plant. A significant increase in concentrations of NO2 in the atmosphere of the industrial areas was recorded in the first decade. On average during three years the highest content of technogenic dust was detected in El Bouni.

The aim of the study was to investigate the content of trace elements in deposited particulate matter and to estimate the health risk to Kraków inhabitants, caused by the exposure to heavy metals in particulate matter deposition. The qualitative and quantitative assessments of selected heavy metals in deposited particulate matter have been carried out in the city of Kraków (Małopolska, southern Poland, 5 measuring points) for seven months, between February and September 2017. A comparative study was conducted at the same time in Małopolska (5 measuring points). The deposited particulate matter was collected gravitationally, using measurement plates covered with aluminum foil and paraffin jelly. The largest deposition of particulate matter was found in May and June. The highest amount of deposited particulate matter and metals present in it was determined in Kraków. The Hazard Quotient (HQ) evaluation for non-carcinogenic effect showed low risk for each metal. In the case of lead in particulate matter, the carcinogenic risk value did not reach 10−6 hence this risk is acceptable. The total carcinogenic risk for all routes of exposure to cadmium was higher, indicating the risk of cancer in children and adults, with children more exposed. However, the carcinogenic risk for cadmium was also acceptable. The study showed that the problem of poor air quality concerns not only the city of Kraków, but also the entire Małopolska region. Elevated metal concentrations in particulate matter indicate the need for monitoring it in the air.

Opis:
Water bodies are the final sinks of all pollution with more than 90% of contaminants found in suspended particulates and bottom sediments. Only less than 10% is retained in the water column yet it attracts and receives great research attention. The pollution status and the potential ecological risk of three pools of water along a stream due to heavy metal enrichment from a nearby active gold mining tailings dam were assessed. The upstreamdownstream and sedimentological approaches to ecosystem health assessment were used. Potential uses of pool water were also evaluated based on measured water quality parameters. Heavy metals in water and sediment were determined using Flame Atomic Absorption Spectrometry. Results revealed that salinisation, acidification and heavy metals were exported from a mining tailings dam to the stream. The degree of contamination of pool water by heavy metals dictated water uses. Heavy metal concentrations imposed water use restrictions for aquatic life in a pool which directly received discharge from the mine tailings dam. The average heavy metal concentrations in sediments were lower than the standard shale values. Sediment quality guidelines and pollution indices showed that the stream was not polluted with heavy metals, thus posed no potential ecological risk. Continuous monitoring of tailings discharge and wash off is important to safeguard aquatic ecosystem and public health.

Opis:
Objectives There are a few accepted and intensively applied statistical methods used to study associations of ambient air pollution with health conditions. Among the most popular methods applied to assess short term air health effects are case-crossover (using events) and time-series methodologies (using counts). A few other techniques for studying counts of events have been proposed, including the Generalized Linear Mixed Models (GLMM). One suggested GLMM technique uses cluster structures based on natural embedded hierarchies: days are nested in the days of a week (dow), which, in turn, are nested in months and months in years (< dow, month, years >). Material and Methods In this study the authors considered clusters with hierarchical structures in a form of < dow, 14-days, year >, where the 14-days hierarchy determines 7 clusters composed of 2 days (the same days) of a week (2 Mondays, 2 Tuesdays, etc.), in 1 year. In this work the authors proposed hierarchical chained clusters in which 2 days of a week are grouped as follows: (first, second), (second, third), (third, fourth) and so on. Such an approach allows determination of an additional series of the slopes on the clusters (second, third), (fourth, fifth), etc., i.e., estimation of the coefficients for other configurations of air pollutant levels. The authors considered a series of 2 point chained clusters covering a year. In such a construction each cluster has one common data point (day) with another one. Results The authors estimated coefficients (slopes) related to the ambient ozone exposure (mortality) and to 3 selected air pollutants (particulate matter, nitrogen dioxide and ozone) combined into index and considered as health risk exposure (emergency department (ED) visits). The generated results were compared to the estimations obtained from the time-series method and the time-stratified case-crossover method applied to the same data. Conclusions The proposed statistical method, based on the chained hierarchical clusters (< dow, 14-days, year >), generated results with shorter confidence intervals than the other methods.

The authors explored the utilization of simulation models as a means to ensure environmental safety, using the industrial hub of Kemerovo as an illustrative example. The article analyzes the factors that have contributed to the deterioration of the environment in the region for decades. It has been established that in terms of the overall percentage distribution of emissions from stationary sources, energy enterprises (73.0%), chemical and petrochemical industries (4.7%), and black metallurgy enterprises (7.8%) are leading in the city of Kemerovo. Simulation modelling has shown that the cause of high concentrations of harmful substances in the atmosphere of Kemerovo is due to the negative factors of industrial and household activities and their impact on environmental safety. High correlation and sensitivity coefficients indicate a lack of new available technologies in the region's industry and transport that could prevent air pollution. The forecasting model has indicated a potential two, three or even greater increase in emissions. For example, in the long-term perspective, by 2063, manufacturing emissions could potentially increase by 35 times, leading to irreversible ecological consequences. Extreme pollution and depletion of natural resources could make living in this region impossible.

Opis:
The methodology of environmental risk is becoming more common to assess the impact of chemical pollution on human beings and the environment, providing information for making environmental remediation decisions. This article examines the impact on human health chemicals that penetrated into river water as a result of an accident at a military ammunition depot. The river is the source of drinking water for the population. Assessing the impact of chemicals on the health of adults, adolescents and children is carried out in stages (tiers), from simple to complex. Assessment is carried out both for carcinogenic and non-carcinogenic substances. The first tier is executed by a deterministic method – a method in which all biological, chemical, physical, and environmental parameters are assumed to be constant and can be accurately specified. Deterministic methods commonly apply to either a “most likely” value for a parameter, or a conservative value. When the obtained values are insufficient for making the decision, the second tier of a risk assessment begins. The values in this case have the form of probability distributions that determine their variability. Processing the risk model with the help of the one-dimensional Monte Carlo method gives more accurate data in the form of risk distribution. However, the method does not consider the lack of knowledge about the values of input variables, so, at the third tier of a risk assessment, the two-dimensional Monte Carlo method is used. In this case, the specified values of risk look like trend charts and indicate the limits of probability of risk for a certain percentage of the population.

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.

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:
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.

Opis:
Środowisko naturalne stale zanieczyszczane jest przez różne substancje. Jednym z typów zanieczyszczeń środowiska naturalnego są farmaceutyki oraz ich metabolity. Ich obecność wykrywana jest w środowisku wodnym oraz glebowym. Ponadto zanieczyszczenie środowiska naturalnego przez farmaceutyki stale się zwiększa, co jest wynikiem rozwijającego się przemysłu farmaceutycznego, a także większego wykorzystania leków w gospodarstwach domowych. Nie bez znaczenia jest także nadużywanie farmaceutyków w rolnictwie, gdzie służą do zwiększenia jakości plonów lub do stymulowania wzrostu zwierząt gospodarczych. Ten nasilający się problem niesie za sobą wiele zagrożeń, zarówno dla ekosystemów, jak i dla zdrowia ludzkiego, bowiem farmaceutyki mogą wtórnie kumulować się w roślinnych i zwierzęcych tkankach, które stanowią źródło pożywienia dla człowieka. Ponadto, obecność tych substancji w środowisku powoduje narastanie zjawiska antybiotykooporności wśród mikroorganizmów w nim bytujących. Aby zapobiegać tym negatywnym skutkom zanieczyszczenia środowiska przez leki, należy przede wszystkim zminimalizować ich przedostawanie się do naturalnych ekosystemów. Działania w tym zakresie powinny być wielokierunkowe i obejmować sprawniejsze usuwanie farmaceutyków w procesie oczyszczania ścieków, zmniejszenie ilości farmaceutyków wykorzystywanych w rolnictwie, a także edukację społeczeństwa.
The natural environment is constantly polluted by various substances. One of the types of environmental pollution are pharmaceuticals and their metabolites. Their presence is detected in the water and soil environment. Moreover, pollution of the environment by pharmaceuticals is constantly increasing as a result of the growing pharmaceutical industry as well as the increased use of drugs in households. Another important factor is the abuse of pharmaceuticals in agriculture, where they are used to increase the quality of crops or to stimulate the growth of livestock. This growing problem carries many threats, both for ecosystems and for human health, because pharmaceuticals can accumulate in plant and animal tissues, which are a source of human food. Moreover, the presence of these substances in the environment increases the phenomenon of antibiotic resistance among the microorganisms living in it. In order to prevent these negative effects of environmental pollution from drugs, it is essential to minimize their leakage into natural ecosystems. Activities in this area should be multidirectional and include more efficient removal of pharmaceuticals in the wastewater treatment process, reduction of the amount of pharmaceuticals used in agriculture, and education of the society.

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:
Public crude oil fields in Wonocolo sub-district were active from 1942 until now and have inadequately operated. The aims of this research were to measure the level of total petroleum hydrocarbon (TPH) pollution and their distribution in soil and surface water at the Wonocolo public crude oil fields. Twelve composite soil samples were collected from uncontaminated and contaminated sites of old well (OW), transportation line (T), and refinery area (R) at the depths of 0–30 cm, 30–60 cm, and 60–90 cm. The composite surface water sample was obtained from two points with different distances from the river side. TPH from soil and surface water samples were extracted using soxhlet and gravimetric method. Quantification of TPH was performed using Fourier Transform Infrared (FT-IR) Spectrometer. From the results of this study, it was concluded that soils and surface water are contaminated by TPH of 119.80–107,190 µg/g and 211,025.73 µg/L, respectively. TPH is clearly located in the upper of 0–30 cm depth at OW, T, and R sites (52,328.14–107,189.63 µg/g). These concentrations exceeded the soil quality standard of TPH and classified as category A for human hazard risk. The findings from this study show that there are considerable health risks which are potentially poisonous to humans in the local area. We recommend that remediation could be conducted using biological methods to reduce TPH pollution level.

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.
