Opis:: The aim of the study is to present the FAPPS (Forecasting of Air Pollution Propagation System) based on the CALPUFF puff dispersion model, used for short-term air quality forecasting in Krakow and Lesser Poland. The article presents two methods of operational air quality forecasting in Krakow. The quality of forecasts was assessed on the basis of PM10 concentrations measured at eight air quality monitoring stations in 2019 in Krakow. Apart from the standard quantitative forecast, a qualitative forecast was presented, specifying the percentage shares of the city area with PM10 concentrations in six concentration classes. For both methods, it was shown how the adjustment of the emissions in the FAPPS system to changes in emissions related to the systemic elimination of coal furnaces in Krakow influenced the quality of forecasts. For standard forecasts, after the emission change on June 7, 2019, the average RMSE value decreased from 23.9 μg/m3 to 14.9 μg/m3, the average FB value changed from -0.200 to -0.063, and the share of correct forecasts increased from 0.74 to 0.91. For qualitative forecasts, for the entire year 2019 and separately for the periods from January to March and October to December, Hit Rate values of 5.43, 2.18 and 3.48 were obtained, the False Alarm Ratios were 0.28, 0.24 and 0,26, and the Probability of Detection values were 0.66, 0.75, and 0.74. The presented results show that the FAPPS system is a useful tool for modelling air pollution in urbanized and industrialized areas with complex terrain.
Celem opracowania jest zaprezentowanie systemu FAPPS opartego o model dyspersji obłoku CALPUFF, wykorzystywanego do prognozowania krótkoterminowego jakości powietrza w Krakowie i Małopolsce. W artykule opisano system modelowania oraz przedstawiono dwie metody operacyjnego prognozowania jakości powietrza w Krakowie. Dla każdej z metod przedstawiono sposób przeprowadzenia oceny sprawdzalności prognoz. Jakość prognoz oceniano na podstawie stężeń pyłu zawieszonego PM10 mierzonych w ośmiu stacjach monitoringu jakości powietrza w 2019 roku w Krakowie. Oprócz standardowej prognozy ilościowej zaprezentowano jakościową prognozę obszarową, określającą udziały procentowe powierzchni miasta ze stężeniami PM10 w sześciu klasach stężeń. Dla obu metod pokazano jak dostosowanie emisji w systemie FAPPS do zmian emisji związanych z systemową eliminacją palenisk węglowych w Krakowie wpłynęło na jakość prognoz. Po zmianie emisji w dniu 7 czerwca 2019 średnia wartość RMSE spadła z 23,9 μg/m3 do 14,9 μg/m3, średnia wartość FB zmieniła się z -0,200 do -0,063, a udział poprawnych prognoz wzrósł średnio z 0,74 do 0,91. Jakość prognoz obszarowych oceniono dla całego roku 2019 i dwóch okresów sezonu grzewczego od stycznia do marca i od października do grudnia. Dla całego roku i obu okresów grzewczych uzyskano odpowiednio wartości Hit Rate równe 5.43, 2.18 i 3.48, wartości współczynnika fałszywych alarmów FAR równe 0.28, 0.24 i 0.26, a wartości prawdopodobieństwa wykrycia POD równe 0,66, 0.75 i 0.74. Przedstawione wyniki pokazują, że system FAPPS jest użytecznym narzędziem do modelowania zanieczyszczenia powietrza w zurbanizowanym i uprzemysłowionym terenie o skomplikowanej rzeźbie terenu.

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:: Determining the level of solid pollution in beach sands located near artificial inland water bodies in order to maintain high safety standards is a difficult and expensive task. The tests aimed at determining beach pollution caused by solid wastes through analysis of toxic and chemical concentrations, are time-consuming and usually require several days before the results are available. In addition, the maintenance of the beach area involving beach raking or grooming, and the seasonal replenishment of sand makes it difficult to realistically determine the chemical or bacterial contamination of the tested material. Solid pollutants, such as glass, caps, cans, thick foil, metal, and plastic fragments, pose a greater health risk to beachgoers. The above-mentioned pollutants, especially small ones, are hardly visible on the surface or they are buried at shallow depths. Beach garbage poses a serious threat that can lead to infections from cuts and scratches. These injuries can become infected, further jeopardizing the health and lives of beachgoers due to risks like tetanus, staphylococcus, etc. The authors presented a new petrographic method aimed at assessing the quality of sand by examining the content of solid pollutants. The obtained results allowed us to conclude that the mentioned procedure can be used for a quick quantitative estimation of the content of potentially dangerous and undesirable pollutants in beach sands. Consequently, the method implemented to determent the amount of solid pollutants in beach sands has proven to be a valuable tool for recreational facility administrators, helping them in taking necessary measures to ensure the safety of beach users. Petrographic analysis of beach sands revealed the presence of pollutants of plant origin (0.4–1.8%), plastic (0.1–0.4%), paper (0.1–0.6%), charcoal (0.1–0.5%), glass (0.1–0.4%), metals (0.1–0.4%), rust (0.1–0.3%), ash and slag (0.1–0.3%), and fossil coals (0.1–0.2%).

Opis:: Though Municipal Solid Waste (MSW) is a worldwide problem, the collected wastes are dumped in open dumping at landfilling sites while the uncollected wastes remain strewn on the roadside, many-a-time clogging drainage. Such unsafe and inadequate management of MSW causes spread of bacteria, viruses, particulate matter, dioxins and other harmful pollutants in the surroundings and atmosphere. Hence, due to the repeated exposure of population to these pollutants can lead to serious health problems such as Diarrhea/Dysentery, Acute Respiratory Infection (ARI), and Asthma/Chronic Respiratory Diseases (CRD). Therefore, two-phase study included secondary data on diseases caused due to environmental pollution and primary data on MSW and lack of MSW management from 127 households in urban Patna, India. The random sampling method was used for collection of primary survey data, conducted during 2015–16 in selected areas of Patna. Logistic regression model odds ratios and their 95% confidence intervals were used to show the strength of the associations among segregation of wastes at source, segregation behavior, collection bins in the area, distance of collection bins from a residential area, and transportation of MSW. The ROC is a statistical technique to validate the logistic regression method that predicts the occurrence of an event through the comparison of probability picture of an event occurrence observed by probability and the predicted probability of the same event. The area under the ROC curve is up to 0.889 extent, which reveals that the ‘segregation of waste at source’ has a very strong scope to accomplish sustainable recycling at urban Patna in order to manage waste with the overall accuracy of 92.126%, which proves a better fi t logistic regression model. Hence, this paper concludes that ‘segregation of waste at source’ helps to attain sustainable recycling which would be the most viable approach to manage MSW in Patna and would eventually reduce environmental pollutants for the public health safety.

Opis:: Bacterial infections that are due to consumption of poor quality water are still an important threat to human health and life. The aim of the article was to investigate the bacteriological threat of water from home wells. The results of water testing from individual wells constituted research material. On their basis, the health risk of fecal streptococci, coliforms and Escherichia coli was assessed and an attempt was made to assess the impact of pollution on the health of residents. The results of water testing in private wells showed unacceptable values for bacteriological pollution. A significant health risk was found for fecal streptococci, coliforms and Escherichia coli. The authors pointed out the need to take extensive actions aimed at raising environmental and health awareness of the inhabitants in terms of water quality used for living purposes, in particular for consumption.

Opis:: Contamination of soil with heavy metals has become a worldwide environmental problem, and receives great attention. In this study, we aim to investigate soil pollution level affected by an industrial district nearby. The total amount of typical heavy metals in the soils (Hengyang Songmu Industrial Park, Hunan Province, China) was analyzed. In addition, the fraction analysis and laboratory simulation leaching via different pH rainwater was carried out to study the migration and transformation of heavy metals. The main results show that the contents of Cu, Zn, Pb, Cr and Cd in the samples were higher than the soil background values in Hunan Province. The heavy metals forms, analyzed by sequential extraction method, show that the proportion of the unstable form of Cd, Zn and Pb was more than 50%. I_geo values indicate that the heavy metal pollution degree of soil sample #5 at the investigated area is recorded in the order of Cd(6.42), Zn(2.28), Cu(1.82), Pb(1.63), and Cr(0.37). Cu, Zn, Pb, Cr and Cd in this area could pose a potential leaching risk to the environment which may affect the food chain and constitute a threat to human health. It would be necessary to take steps to stabilize and monitor the heavy metals in soil.

Opis:: The increasing demand for noble metals boosts their price. In order to meet the increasing demand for elements, a number of technologies are being developed to recover elements already present in the environment. Traffic-related metal pollution is a serious worldwide concern. Roadside soils are constantly subjected to the deposition of metals released by tailpipe gases, vehicle parts, and road infrastructure components. These metals, especially platinum group elements from catalytic converters, accumulating in the soil pose a risk both for agricultural and residential areas. Phytomining is suggested as a novel technology to obtain platinum group metals from plants grown on the contaminated soil, rock, or on mine wastes. Interest in this method is growing as interest in the recovery of rare metals is also increasing. Based on the research of many authors, the sources and amounts of noble metals that accumulate in soil along communication routes have been presented. The paper presents also plants that can be used for phytomining.
Aby sprostać rosnącemu zapotrzebowaniu na metale szlachetne poszukuje się technologii odzyskiwania pierwiastków już obecnych w środowisku. Gromadzące się w glebie metale, zwłaszcza pierwiastki z grupy platynowców pochodzące z katalizatorów, stanowią zagrożenie dla środowiska. Fitoekstrakcja jest technologią wykorzystywaną do pozyskiwania metali z grupy platynowców z roślin rosnących na zanieczyszczonej glebie, skale lub odpadach kopalnianych. Zainteresowanie tą metodą rośnie wraz ze wzrostem zainteresowania odzyskiem metali rzadkich. Na podstawie wyników badań różnych autorów przedstawiono ilości metali szlachetnych gromadzących się w glebie wzdłuż szlaków komunikacyjnych. W pracy przedstawiono także rośliny, które można wykorzystać do fitoekstrakcji.

Opis:: The prediction of PM2.5 is important for environmental forecasting and air pollution control. In this study, four machine learning methods, ground-based LiDAR data and meteorological data were used to predict the ground-level PM2.5 concentrations in Beijing. Among the four methods, the random forest (RF) method was the most effective in predicting ground-level PM2.5 concentrations. Compared with BP neural network, support vector machine (SVM), and various linear fitting methods, the accuracy of the RF method was superior by 10%. The method can describe the spatial and temporal variation in PM2.5 concentrations under different meteorological conditions, with low root mean square error (RMSE) and mean square deviation (MD), and the consistency index (IA) reached 99.69%. Under different weather conditions, the hourly variation in PM2.5 concentrations has a good descriptive ability. In this paper, we analyzed the weights of input variables in the RF method, constructed a pollution case to correspond to the relationship between input variables and PM2.5, and analyzed the sources of pollutants via HYSPLIT backward trajectory. This method can study the interaction between PM2.5 and air pollution variables, and provide new ideas for preventing and forecasting air pollution.

Opis:: Heavy metal pollutants in the leachate of waste landfill are a potential threat to the environment. In this study, the feasibility of using municipal sewage sludge as barrier material for the containment of heavy metal pollutants from solid waste landfills was evaluated by compaction test and hydraulic conductivity test concerning compaction property, impermeability and heavy metal retardation. Results of the compaction test showed that the maximum dry density of 0.79 g·cm⁻³ was achieved at the optimum water content of about 60%. The hydraulic conductivities of compacted sewage sludge permeated with synthetic heavy metal solutions were in the range of 1.3×10⁻⁸ – 6.2×10⁻⁹ cm·s⁻¹, less than 1.0 ×10−⁻⁷cm·s⁻¹ recommended by regulations for barrier materials. Chemical analyses on the effluent from the hydraulic conductivity tests indicated that the two target heavy metals, Zn and Cd in the permeants were all retarded by compacted sewage sludge, which might be attributed to the precipitation and adsorption of heavy metal ions. The results of this study suggest that specially prepared material from sewage sludge could be used as a barrier for waste landfills for its low permeability and strong retardation to heavy metal pollutants.

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:: Microbiological and chemical analysis of air was carried out on the area of landfill of wastes other than inert or hazardous. The landfill covers 20 ha and 40 000 Mg of wastes is deposited annually. Municipal waste is not segregated at the landfill. The research was conducted in April, May and November 2012. Number of the psychrophilic and mesophilic bacteria and fungi was estimated by a culture-based method. Quantitative determination of sulfur compounds and meteorological and olfactrometric examinations were also carried out. Chemical analysis was conducted with a Photovac Voyager portable gas chromatograph. Air samples were collected at 5 points. The largest group of microbes were psychrophilic bacteria, especially in summer. The highest concentration of hydrogen sulfide and other odorants was found at leachate tank and landfill body. According to the Polish Standard for the assessment of atmospheric air pollution the air in the area of the landfill is classified as not contaminated and sporadically moderately contaminated. In spring and summer the number of microscopic fungi was increased also in control samples.
Przeprowadzono badania nad zanieczyszczeniem powietrza na terenie składowiska odpadów innych niż obojętne i niebezpieczne. Wybrany obiekt został otwarty w 1997; zajmuje 20 ha i rocznie przyjmuje 40 000 Mg odpadów komunalnych, które nie podlegają segregowaniu na składowisku. Zakres badań mikrobiologicznych obejmował analizę ilościową bakterii mezofilnych, psychrofilnych oraz grzybów mikroskopowych. Do poboru próbek powietrza zastosowano metodę zderzeniową. Analizy chemiczne polegały na oszacowaniu stężenia siarkowodoru oraz merkaptanu etylowego i metylowego za pomocą przenośnego chromatografu Photovac Voager. Określano ponadto takie parametry jak prędkość i kierunek wiatru oraz intensywność zapachu. Pobór próbek przeprowadzono w pięciu punktach. Wykazano emisję mikroorganizmów oraz siarkowodoru i odorów z terenu składowiska. Najliczniejszebyły bakterie psychrofilne, zwłaszcza w porze letniej. Wysoką liczbę bakterii mezofilnych i grzybów mikroskopowych stwierdzono na bryle czynnego składowiska. Najwyższe stężenie siarkowodoru i odorów wykryto w sąsiedztwie zbiornika na odcieki oraz na składowisku. Na podstawie polskiej normy dotyczącej jakości powietrza atmosferycznego należy określić powietrze na terenie składowiska jako nie zanieczyszczone (liczba grzybów) oraz średnio zanieczyszczone i nie zanieczyszczone (liczba bakterii psychrofilnych). Wiosną i latem zaobserwowano podwyższoną liczbę grzybów mikroskopowych również w próbkach kontrolnych.

Opis:: The aim of this study was to investigate the dynamics of changes in the metal concentrations in the soils contaminated with Cd, Pb, and Zn during a 5 year period. Additionally the purpose included assessment of the suitability of 1 M HCl to control soil contamination with heavy metals compared to using of aqua regia method. The study was conducted in concrete-framed microplots, filled with two soils (sandy and silty), which were artificially co-contaminated with Cd, Pb and Zn. There was a gradual decrease in these concentrations during the 5 year period. The concentrations of the metals extracted with 1 M HCl were very similar to the total concentrations. After 5 years of research, the topsoil had the smallest decrease in Pb concentration, which for the sandy, and silty soils was, respectively, by 7% and 9% in relation to the initial value. The concentrations of Cd and Zn decreased by up to about 35% in the sandy soil and by about 20% in the silty soil. Sandy soil contamination with metals poses a potentially higher threat to humans and the environment than silty soil contamination. Therefore, the examination of the sandy soils contamination, as well as of the groundwater occurring in these areas, should be carried out at least once for 5 years. It has been shown that the analytical method using aqua regia can be replaced by 1 M HCl method to track changes of metals concentration in the soil, that occur over time period.
Celem pracy było zbadanie dynamiki zmian zawartości metali w glebach zanieczyszczonych Cd, Pb i Zn w okresie 5-letnim. Dodatkowym celem była ocena przydatności 1 M HCl do kontroli stanu zanieczyszczenia gleby tymi metalami w porównaniu z metodą z użyciem wody królewskiej. Doświadczenie przeprowadzono w obetonowanych mikropoletkach wypełnionych dwoma glebami (piaskową i pyłową), które zostały symulacyjnie skażone Cd, Pb i Zn. Stwierdzono stopniowe obniżanie się zawartości tych metali w glebie wraz z upływem czasu, przy czym zawartości te, oznaczone po ekstrakcji metali z gleby 1 M HCl, były bardzo podobne do zawartości całkowitych oznaczonych z użyciem wody królewskiej. Po 5 latach badań górna warstwa gleby (0–20 cm) wykazywała spadek koncentracji Pb, który w glebie piaskowej i pyłowej wynosił odpowiednio 7% i 9% w stosunku do wartości początkowej. Zawartości Cd i Zn obniżyły się o około 35% w glebie piaskowej i 20% w pyłowej. Badania wykazały, że gleba piaskowa zanieczyszczona metalami stwarza większe potencjalne zagrożenie dla ludzi i środowiska, niż zanieczyszczona gleba pyłowa. Dlatego kontrola zanieczyszczonych gleb piaskowych, jak również wód podziemnych znajdujących się na tym obszarze, powinna być prowadzona co najmniej raz na 5 lat. Wykazano, że w celu śledzenia zmian zawartości badanych metali w glebie, jakie następują w danym okresie czasu, metodę analityczną z użyciem wody królewskiej można zastąpić tańszą i łatwiejszą metodą z użyciem1 M HCl.

Opis:: Persistent organic pollutants (POPs) originating from agrochemical industries have become an urgent environmental problem worldwide. Ordinary kriging, as an optimal geostatistical interpolation technique, has been proved to be sufficiently robust for estimating values with finite sampled data in most of the cases. In this study, ordinary kriging interpolation integrate with 3D visualization methods is applied to characterize the monochlorobenzene contaminated soil for an agrochemical industrial site located in Jiangsu province. Based on 944 soil samples collected by Geoprobe 540MT and monitored by SGS environmental monitoring services, 3D visualization in terms of the spatial distribution of pollutants in potentially contaminated soil, the extent and severity of the pollution levels in different layers, high concentration levels and isolines of monochlorobenzene concentrations in this area are provided. From the obtained results, more information taking into account the spatial heterogeneity of soil area will be helpful for decision makers to develop and implement the soil remediation strategy in the future.

Opis:: Nutrient pollution such as nitrate (NO₃−) can cause water quality degradation in rivers used as a source of drinking water. This situation raises the question of how the nutrients have moved depending on many factors such as land use and anthropogenic sources. Researchers developed several nutrient export coefficient models depending on the aforementioned factors. To this purpose, statistical data including a number of factors such as historical water quality and land use data for the Melen Watershed were used. Nitrate export coefficients are estimates of the total load or mass of nitrate (NO₃−) exported from a watershed standardized to unit area and unit time (e.g. kg/km²/day). In this study, nitrate export coefficients for the Melen Watershed were determined using the model that covers the Frequentist and Bayesian approaches. River retention coefficient was determined and introduced into the model as an important variable.
