Opis:: The aim of the statistical analyses carried out was to identify similarities and to point out differences between the various tributaries of the Narew River, to identify the factors and processes responsible for the transformations occurring in the aquatic environment and finally, to identify the main sources of pollution in the river catchment. For the purposes of statistical analysis, the results of studies conducted as part of diagnostic monitoring by the General Inspectorate for Environmental Protection in 2017–2018 were used. The studies included 8 measurement points located directly on the Narew River and 17 points located on its selected left and right tributaries. Analysis of the collected results indicates that the chemical condition of the water in the Narew catchment is assessed as being poor. This observation may be due to the fact that the Narew catchment is mainly used for agricultural purposes and, in addition, there is a relatively large number of potential anthropogenic sources. As part of the analysis, two potential sources of pollution affecting water quality in the Narew catchment were identified, which include surface run-off and treated wastewater inflow.

Opis:: The impact and occurrence of human-induced pollution sources have been investigated in one of the few remaining urban streams located in Attica, Greece. Baseline information is provided on the presence and concentration of physicochemical parameters, nutrients, total coliforms, hydrocarbons and phenols in 12 key points along the Pikrodafni stream. The aim was to evaluate the relative importance of key water quality variables and their sources. Indicator substances (i.e. concentrations of nitrate, ammonium, phosphate and total coliforms in certain stations indicating wastewater exposure; PAHs indicating petroleum sources) successfully related the water quality variables to pollution sources. Furthermore, a pollution pressure map has been developed with the activities identified from in-situ visits and Google Earth surveys, while the statistical analysis (CA and PCA) has contributed to the further exploration of the relative magnitude of pollution sources effects. Our results underline initially the importance of diffuse pollution management accompanied by the necessity for continuous environmental monitoring and the application of legal and environmental restoration actions if water quality is to be improved according to WFD 2000/60/EC.

Opis:: Atmospheric deposition, vehicular transportation and de-icing agents are major sources polluted snow in urban. This study investigates the current trace elements concentrations of snow and de-icing using ICP-MS, and phytotoxicity using three vascular plants in snow. The study assesses the contamination, classification and phytotoxicity of snow quality removed from roads of residential areas and piled on children’s playgrounds in residential territories. The research found that according to Russian environmental quality standard for water has been identified the exceeding trace elements in snow by W, Se, Mn, Cu, V, Mo, Ni and Zn. The pollution indices (PLI, CF and Zc) were identified pollution level of snow piles from moderate contamination to very high contamination. Based on average germination index values for Sinapis alba L., Lepidium sativum L., and Triticum aestivum L., the degree of inhibition in snow piles varied from no inhibition to strong inhibition. The trace elements content in de-icing “Galit А” and salt sand mix are defined in the following descending order: Zn > Mn > Ba > V > Rb > Sr and Mn > Ba > Cr > V > Sr > Ni, respectively. High concentrations of trace elements in snow piles are a source of environmental pollution. To prevent snow storage and disposal in residential areas should be involved in future studies of environmental pollution and circular economy, so that environmental managers can reduce threats to the environment and public health, as well as initiate circular economy projects in urban areas.

Opis:: The Kelani River is the second largest watershed in Sri Lanka and the main water-supply intake point for the Greater Colombo. The present study focuses to identify the sources of pollutants of the meandering zone of the Kelani River, particularly due to the absence of more recent information. Accordingly, a survey was conducted to obtain information on industrial discharges, anthropological, and social activities within the area of 15 m from left and right banks of the river. The high contaminations (total and faecal coliform – 1100 MPN∙(100 cm3)–1; COD – 10 mg∙dm–3; BOD – 4 mg∙dm–3) of surface and groundwater are corroborated with the results obtained via the demographic and land usage statistics. Industrial pollutant sources and harmful anthropological practices were identified as major threats to the river basin. In this survey, agriculture and land degradation were identified as issues due to improper land use management. As policy recommendations based on the results of the study, it was identified that the awareness for Kelani River protection should be increased; monitoring and evaluation of the Kelani River basin under a management plan should be implemented; and stakeholder and private partnerships contribution to the sustainability of the Kelani River basin should be established.

Opis:: W pracy przedstawiono skład powietrza atmosferycznego jako mieszaninę gazów tworzących składniki stałe i zmienne oraz przywołano definicje zanieczyszczeń powietrza. zdefiniowano zanieczyszczenia gazowe i stałe (pyły) powietrza atmosferycznego. Dokonano podziału pyłów według różnych kryteriów oraz przedstawiono ich właściwości. Podano przykładowe przebiegi imisji frakcji cząstek stałych, wskazując na silną zależność imisji od pór roku, dni tygodnia oraz dnia i nocy. Przedstawiono źródła i charakterystykę zanieczyszczeń sztucznych i naturalnych powietrza atmosferycznego. Wykazano, że głównym źródłem zanieczyszczeń antropogenicznych oprócz przemysłu jest motoryzacja. Silniki spalinowe samochodów to źródło zanieczyszczeń gazowych oraz cząstek stałych. Samochody emitują zanieczyszczenia ze zużycia okładzin ciernych hamulców, sprzęgieł oraz ze zużycia opon i jezdni. Omówiono główne źródła naturalnych zanieczyszczeń powietrza, w tym wybuchy wulkanów, pożary składowisk odpadów, lasów, stepów oraz burze piaskowe, a także pył mineralny (pył drogowy) unoszony z podłoża przez pojazdy. Przedstawiono właściwości pyłu drogowego: skład chemiczny i frakcyjny, gęstość, stężenie pyłu w powietrzu. Wykazano, że dwa podstawowe składniki pyłu, krzemionka i korund, których udział w pyle dochodzi do 95%, mają jednocześnie największą twardość, która może mieć decydujący wpływ na zużycie elementów silnika. Przedstawiono różne wartości stężenia pyłu w powietrzu - w zależności od rodzaju i stanu podłoża oraz warunków użytkowania pojazdów.
The paper presents the composition of atmospheric air as a mixture of gases that make up the solid and variable components, and the definitions of air pollutants are referenced. Gaseous and solid pollutants (dust) of the atmospheric air have been defined. Dusts were divided according to various criteria and their properties were given. exemplary courses of immission of the fraction of solid particles are given, indicating a strong dependence of the immission on the seasons, days of the week and day and night. The sources and characteristics of artificial and natural pollutants in the atmospheric air are presented. it has been shown that the main sources of anthropogenic pollution, in addition to industry, is the automotive industry. Cars are a source of gaseous and particulate pollutants Pm, and they also emit pollution from brake and clutch lining wear, as well as from tire and road wear. The main sources of natural air pollution were discussed, including volcanic eruptions, fires in landfills, forests, steppes and sand storms, as well as mineral dust (road dust) carried from the ground by vehicles. The properties of road dust are discussed: chemical and fractional composition, density, and dust concentration in the air. it has been shown that the two basic components of the dust, silica and corundum, whose share in dust reaches 95%, also have the highest hardness, which may have a decisive influence on the wear of engine components. Various values of dust concentration in the air were presented depending on the type and condition of the ground and the conditions of used vehicles.

Opis:: With the advancement of industrialization, the problem of atmospheric environmental pollution is becoming more and more prominent. To solve this problem, an unmanned aerial vehicle (UAV) as an airborne platform was used to design an air pollution source localization method based on an anxiety-auction algorithm and verify the feasibility of the algorithm through simulation analysis and indoor source localization experiments. The algorithm innovatively introduces the concept of anxiety in psyhology into the traditional auction algorithm. By enabling each drone to make a “rational” auction time decision based on its emotional state, team resources can be conserved, and overall source localization efficiency can be enhanced. Based on different environmental factors and conditions, the number of drones and other multi-perspective comparison analyses with the traditional auction algorithm, the analysis results show that the anxiety-auction algorithm performs better in terms of success rate and distance ratio. This paper also built a set of atmospheric pollutant source localization platforms, consisting of an ultra-wideband (UWB) indoor positioning device, UAV platform, source localization monitoring and control module, and the indoor source localization experiment of atmospheric pollutants based on multiple UAVs was successfully designed and carried out.
