Opis:
The work presented the assessment of household wastewater treatment plants with drainage systems on the quality of groundwater in dug wells and deep water wells in the area of 3 selected communes (Drelów, Dębowa Kłoda and Urszulin), located in the Lublin province in south-eastern Poland. The investigations of the physicochemical composition of water from selected 28 dug wells and 2 deep water wells were conducted from June to July 2020, involving 9 measurement series. The microbiological studies consisted in 4 measurement series. The composition of the wastewater from primary settling tanks discharged to soil via drainage systems located in the vicinity of considered wells was also examined on a single occasion. The studies indicate that the water from wells are significantly polluted with ammonia, nitrites, as well as compounds of natural origin: iron and manganese. The presence of microbiological pollution of fecal origin was noted. The studies clearly indicate the possible pollution of the analyzed well waters with domestic sewage discharged to soil via drainage systems. Therefore, it necessary to take the actions aimed at improving the quality of groundwater in the Lublin province, including limitation of drainage systems, especially in the areas with unfavorable subsurface and hydrological conditions as well as low water supply coverage. The need to introduce changes in legal regulations and strategies for the development of technical infrastructure in counties, favoring the most efficient, as well as simple and inexpensive technologies, was indicated.

Opis:
The aim of the study was to determine the value and concentration indicators of BOD5, COD and general nitrogen in domestic wastewater after mechanical treatment, which should be considered in the design of the activated sludge reactor. Ninety-nine samples of raw wastewater and after mechanical treatment were then collected and physicochemical analysis was carried out. The quantity of pollutants in the raw wastewater was verified to determine if this was domestic wastewater. The next stage of the analysis included the definition of the characteristic quantity of the analysed indicators in wastewater after mechanical treatment, which should be taken into account while calibrating computer programs supporting the design of biological reactor chambers. A detailed analysis led to the conclusion that mean values for BOD5 - 300 mgO2·dm-3, for COD - 500 mgO2·dm-3and for total nitrogen 50 mgN·dm-3 should be applied. The work also determined the susceptibility of wastewater after mechanical treatment to the decomposition of organic and biogenic compounds.

Opis:
The described experimental study, performed over the years, includes the quantitative and qualitative monitoring of the presence of microorganisms of air in outdoor and indoor environments of the Albanian Capital, Tirana, during a time when large demographic movements, accompanied by critical urban interventions and infrastructural changes have been part of our lives. A project, part of the National Program in Biotechnology (R&D – the year 2000), was the first support to obtain a database on microbiological air pollution in selected urban areas in Tirana and isolate and identify specific air microbial pollutants. The results obtained were an incentive to continue further with additional scientific evaluation monitoring research that included 2011 to 2015 and then those of 2016-2020. Over the years, there has been a significant reduction in pollutant microbial loads (for example, some outdoor areas of the center of Tirana), together with substantial fluctuations in indoor microbial loads, which were observed in many cases. Also, a prominent presence of typical environmental fungi pollutants was identified, such as Aspergillus niger, Aspergillus flavus, Aspergillus terreus, and bacterial pollutants, cocci and bacilli (typical Bacillus megaterium), during Total Viable Count (TVC) and other microbiological tests of identification.

Opis:
This paper discusses generally the possibility of reduction carbon dioxide and nitrogen oxides emissions from internal combustion engines of vehicles by using biomethane. The road transport in Europe almost fully depends on fossil fuels. Diversification of the road transport fuels will be a key attribute for road transport in the coming years. Purified biogas is one of alternative renewable fuels. Actually, in Poland biogas is used for generating electricity and heat. In some countries (for example in Sweden), upgraded biogas to natural gas quality (biomethane) is used as a vehicle fuel too. In this paper estimated biogas production potential in Baltic See Region countries: Poland and Sweden. It was one of the purposes of European Project Baltic Biogas Bus, and it is taken into account in European Project More Baltic Biogas Bus realized presently. Comparative studies of exhaust emissions of carbon dioxide and nitrogen oxides from city buses powered by diesel and CNG engine were carried out. The study was conducted under real traffic conditions in southern Polish city Rzeszow. Due to the lack in-service city buses with emission level Euro V in Rzeszow, comparative studies of this type of city buses powered by diesel and CNG engine was conducted in SORT I test. Determined mean values of road emissions of carbon dioxide and nitrogen oxides in g/km for the city buses operated in Rzeszow. Estimated value of the total road emissions in the case that would be replaced half the fleet of city buses (40 CNG buses and about 35% of the diesel engine powered buses, meet Euro III emission standard) by the CNG-powered (biomethane) city buses, complying with Euro V (EEV) emission standard.

Opis:
Five composite samples of waste water were collected from waste water tank of a vegetable oil refining company and were analyzed for physiochemical characteristics, heavy metal and organic pollutants. Physicochemical determinations were done according to standard methods; heavy metals were determined by use of Atomic Absorption Spectrophotometer method while organic pollutants were determined by Gas chromatography system HP 6890 series. Sulphate was determined by vanadomolybdophosphoric acid method while phosphates and chlorides were determined by argentometric method. Results reveal that effluent pH (4.67 ±0.015), salinity (125 ±4.50 %) and BOD5 (17.83 ±1.70 mg/l) were bellow WHO standard whereas TDS (127.7 ±5.77 mg/l), TSS (563.6 ±3.15 mg/l) and COD (3959 ±3.8 mg/l) were above WHO standards. Heavy metal pollution index (0.31) showed no multi-element contamination arising from effluent. The degree of contamination (1.84) showed that the effluent has a moderate polluting potential. Lower molecular weight PAHs showed a significant difference even though most of the organic compounds in vegetable oil refinery wastewater showed good biodegradability that varied weekly. Therefore there is either no treatment or an in effective treatment of the effluents. This could result to serious environmental problems in the near future.

Opis:
Quality of bottom sediments was examined for 15 reservoirs classified as the Sudeten, Carpathian or lowland reservoirs, according to their location. These reservoirs serve multiple functions including flood control, providing hydroelectric power, supplying water for general public, industry or agriculture and recreational. The study was conducted in 2008 and 2010. The scope of the analysis included trace elements (As, Cr, Zn, Cd, Cu, Ni, Pb and Hg) and organic compounds: polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and chloroorganic pesticides. It was determined that concentration of trace element compounds ranged from <0.01 mg/kg to 422 mg/kg, while of PAHs from <0.0001 mg/kg to 7.5 mg/kg, PCBs from <0.0001 mg/kg to 0.78 mg/kg and of chloroorganic pesticides from <0.0002 mg/kg to 0.065 mg/kg. The sediments from the Sudeten reservoirs were found to be the most polluted, while the sediments from the lowland reservoirs the least.
Wykonano badania jakości osadów dennych pobranych z 15 zbiorników zaporowych, które w zależności od lokalizacji przyporządkowano do grupy zbiorników sudeckich, karpackich lub nizinnych. Zbiorniki te służą do różnych celów, takich jak ochrona przeciwpowodziowa, energetyka wodna, zaopatrzenie w wodę ludności, przemysłu i rolnictwa oraz rekreacja. Badania wykonano w latach 2008 i 2010. Zakres analizy osadów dennych obejmował pierwiastki śladowe (As, Cr, Zn, Cd, Cu, Ni, Pb i Hg) i związki organiczne (wielopierścieniowe węglowodory aromatyczne – WWA, polichlorowane bifenyle – PCB i pestycydy chloroorganiczne). Stwierdzono, że zawartość pierwiastków śladowych w osadach wynosiła od <0,01 mg/kg do 422 mg/kg; WWA od <0,0001 mg/kg do 7,5 mg/kg, PCB od <0,0001 mg/kg do 0,78 mg/kg, a pestycydy chloroorganiczne od <0,0002 mg/kg do 0,065 mg/kg. Najbardziej zanieczyszczone okazały się osady denne pobrane ze zbiorników sudeckich a najmniej z nizinnych.

Opis:
In the large urban areas, in middle latitudes, as in case of Poland, the cause of poor air quality is immission: in winter particulate matter PM10 and PM2.5, in summer - ozone and nitrogen oxides (or nitrogen dioxide). In the whole country, road transport is significantly responsible for the emission of nitrogen oxides (30%), carbon monoxide (20%) and less for emission of particulate matter (a few percent). In the case of other pollutants, the emission of non-metallic organic compounds is less than 10% (including polycyclic organic compounds - just over 0.5%), and sulfur oxides - only 0.03%! To analyze impact of automotive industry on air quality, pollutant emission data from two stations in Krakow were selected. These stations are known for poor air quality - the stations are: Dietla Street - with a high level of traffic and Kurdwanów - place located far from traffic routes. It was found that other objects than automotive vehicles are the dominant source of dust. These are industrial sources and - above all - energy sources, especially individual heating installations. Particularly large dust pollution occurs in winter and it is not always in areas with intense traffic. There was a strong dependence between immission of pollutants and road traffic, however, this dependence is not dominant in assessing the risk of air quality in urban agglomerations.

Opis:
Zanieczyszczenia powietrza oddziałują zarówno na człowieka, jak i całe środowisko naturalne: gleby, wody, ziemię, zwierzęta i rośliny. Jednym z nich jest pył zawieszony. Badania stężeń frakcji tego pyłu PM10, PM2,5, PM1,0 z liniowych źródeł komunikacyjnych zaplanowano i wykonano na Woli, jednej z dzielnic Warszawy. Pomiary za pomocą pyłomierza DustTrak II odbywały się dwa razy w ciągu doby w różnym czasie, ale w tych samych punktach pomiarowych, znajdujących się przy wybranych arteriach komunikacyjnych. Wpływ liniowych źródeł emisji pyłu zależy bardzo często od stanu technicznego pojazdów, ale również bardzo duże znaczenie ma sposób organizacji i natężenie ruchu oraz przepustowość dróg. Zwrócono uwagę na to, że bardzo istotny wpływ na rozkład stężeń pyłu zawieszonego w powietrzu atmosferycznym mają między innymi warunki meteorologiczne. Zjawisko inwersji termicznej w sposób istotny utrudnia ruchy zanieczyszczonych mas powietrza, w wyniku czego masy te kumulują się na danym terenie, powodując gromadzenie się mgły oraz wzmacnianie się smogu na obszarze, gdzie wystąpiła duża emisja zanieczyszczeń.
Air pollution affects both man and the whole natural environment-soil, water, animals and plants. One of the key pollutants of the atmospheric air is the suspended dust. Investigations of the concentrations of this PM10, PM2.5, PM1.0 fractions from linear communication sources were planned and carried out in Wola, one of the Warsaw districts . The measurements using the DustTrak II dust meter took place twice a day at different times, but at the same measuring points located at selected traffic arteries. The influence of linear dust emission sources depends very often on the technical condition of vehicles, but also the manner of organization and volume of traffic as well as road capacity are very important. It has been pointed out that the meteorological conditions have a very significant influence on the distribution of particulate matter suspended in the atmospheric air. The phenomenon of the thermal inversion significantly impedes the movements of the contaminated air masses, as a result of which these masses are cumulated in a given area, causing the accumulation of fog and strengthening the smog in the area where a large emission of pollutants occurred.

Opis:
Przedstawiono sposób oceny wpływu na środowisko wodne nieoczyszczonych ścieków zawierających osad czynny. Odległe w czasie, incydentalne zrzuty ścieków, w szczególności miejskich, wykazują szybki zanik oddziaływania na fazę wodną cieku. W celu wykazania faktu odprowadzenia ścieków, bez względu na ich korzystny czy też niekorzystny wpływ na odbiornik, konieczne było przeprowadzenie badań własności osadów dennych zdeponowanych bezpośrednio powyżej i poniżej przekroju zrzutu ścieków. Zmiana niektórych własności osadu może być wykazana tylko za pomocą modelu matematycznego, opisującego przebiegi procesów zachodzących w próbce wody i próbce wody z osadami. Model matematyczny zawiera równania różniczkowe opisujące zmiany w czasie wskaźników jakości wody oraz koncentracji mikroorganizmów. Równania opisują przebiegi następujących procesów: biochemiczne utlenianie związków organicznych, nitryfikację pierwszego i drugiego stopnia, denitryfikację, amonifikację, defosfatację. W równaniach wzrostu mikroorganizmów uwzględniono asymilację azotu i fosforu. W opisie kinetyki wzrostu organizmów heterotroficznych uwzględniono także respirację endogenną oraz zamieranie komórek. Model matematyczny umożliwił określenie maksymalnych szybkości przemian zanieczyszczeń w próbkach wody i wody z osadami pobranych w przekrojach położonych powyżej i poniżej zrzutu ścieków. Na podstawie informacji o stężeniach wybranych substancji oraz szybkościach procesów biochemicznych w próbkach wody i wody z osadami wykazano istnienie w przeszłości zrzutu ścieków do potoku i jego wpływ na osady denne cieku. Próbki wody zawierające osady, pobrane powyżej i poniżej zrzutu ścieków zawierających osad czynny, miały różne własności. Dodanie osadów do próbki wody powoduje zmianę szybkości procesów biologicznych w porównaniu z tymi, jakie obserwowano w próbkach wody bez osadów. Próbka osadów pobranych w przekroju poniżej zrzutu ścieków, dodana do próbki wody, powoduje wystąpienie gwałtownego zużycia tlenu (procesy chemiczne i/lub biochemiczne) w ciągu pierwszych 6 godzin inkubacji próbki wody z osadem. Zużycie to jest większe od zużycia tlenu w próbce z osadem pobranym powyżej zrzutu ścieków. Warunki beztlenowe, jakie panowały w osadzie pobranym w przekroju poniżej zrzutu ścieków, przyczyniły się do wzrostu organizmów denitryfikujących. Dodanie tego osadu do próbki wody spowodowało wystąpienie procesu denitryfikacji.
The paper presents a method to assess the impact of untreated sewage containing activated sludge on the aquatic environment. Distant in time, incidental sewage discharges, particularly urban show the rapid disappearance of the impact on the aqueous phase of watercourse. In order to demonstrate the fact of sewage discharge, regardless of their beneficial or adverse effect on the receiver, it was necessary to study properties of the deposited sediments directly above and below the cross section of discharge. Amendment of certain properties of sediment can be demonstrated only by means of a mathematical model describing the phenomena in a water sample and in a water sample with the sediments. The mathematical model includes differential equations describing the changes in water quality indicators and concentration of microorganisms with time. The equations describe the following processes: the biochemical oxidation of organic compounds, nitrification of the first and second degree, denitrification, ammonification, defosfatation. The equations of the microbial growth include assimilation of nitrogen and phosphorus. Description of the kinetics of growth of heterotrophic organisms also includes endogenous respiration and decay of cells. The mathematical model allowed the determination of the maximum transformation rates of pollutants in water samples and water samples with sediments collected in sections located above and below the sewage discharge. On the basis of information on concentrations of selected substances and rates of biochemical processes in water samples and water samples with the sediments there has been demonstrated existence in the past the discharge of sewage into the stream and its impact on the stream bottom sediments. Water samples containing sediments above and below the improved discharge wastewater containing activated sludge had different properties. The addition of sediment to the water sample changed the speed of biological processes in comparison with those observed in water samples without the deposits. Sediment sample taken at the discharge section below, added to the samples of water, causes a rapid consumption of oxygen (chemical and/or biochemical processes) during the first 6 hours of incubation of water samples with the sediment. Consumption is greater than the oxygen consumption in a sample of sediment collected above the discharge. Anaerobic conditions that prevailed in the sediment collected in the section below the discharge of sewage contributed to the growth of denitrifying organisms. The addition of sediment to the water sample caused the occurrence of denitrification.

Opis:
The paper presents results of three-dimensional physical modeling and computer simulations of fluid-flow structures, mixing and combustion processes in a 125 MW tangentially fuel-fired boiler and additional fuel - natural gas. This method is commonly called the reburning process, with an emphasis on the reduction of CO, NOx and SOx. The co-firing process is realized between the main coal burners and additional fuel nozzles. To improve the mixing and combustion processes, a physical technique, the so-called acid/alkali technique, is used to optimize the placement and direction of additional air and fuel nozzles. The best result obtained from physical modeling experiments is studied using numerical simulations with the FLUENT commercial code. Numerical modeling results are then used to analyze the performance of an industrial boiler. These results, compared with measurements in a real boiler, seem to be in good agreement with each other.

The paper analyses the ecological properties of taiga topsoil during its commercial development and assesses the consequences of impact which will be made by the future facilities on the environment (taking into account the types of impact, their characteristics, the tendencies of transformation in the nature systems growing with the increase of service life, which were detected at the producing fields), sanitary and socioeconomic aspects of the facilities operation under the conditions of specific geographical complexes. The object of study included waspodzolic and swamp-podzolic soils located in the Uvat district in Khanty-Mansiysk Autonomous Region of Tyumen region, in the area of potential impact of industrial facilities. The method of study implied the selection of soil specimens and their examination according to the standard practices. Ten specimens were taken from each of three areas of sampling. The specimens were subjected to office study in order to determine eleven parameters. The sources of impact made by the oil and gas facility on the environment were the material objects (buildings, constructions etc.), elements and assemblies of basic and auxiliary technologies which result in pollutants emission. The major impact on topsoil at the stage of preparatory works and construction of facilities was the mechanical damage to the natural state of soils. It is primarily connected with sites stripping from forestry and ground leveling. The paper reviews the issues of ecological condition of topsoil and forecast of possible changes while commercial development of the studied area. A negative load on soil may be decreased through planning and implementation of organizational measures on assessment of current state of the topsoil within the field and environmental threat from basic and auxiliary industrial facilities.

The results of the research assessing the possibility of using spider webs for the indication of organic pollutants (PAHs) in the long period of time in the air polluted with road traffic emissions are presented. It was proved that webs could be used for the indication of pollutants of this type. Because of the great availability and dense structure of webs belonging to representatives of Agelenidae family, they can serve as a very effective tool. What is more, the secluded location of webs is favorable and influences the accuracy and credibility of results, since deposited pollutants are not washed off with rain, neither are they decomposed by microorganisms or sunlight. The influence of co-existing contaminants is also minimized.

Opis:
Human activities have a complex and multidimensional impact on water quality. The concentration of inhabitants, production and services intensifies influence of urban agglomerations on water in rivers. Among many sources of surface water pollution, the most important are sewage discharges. The aim of the research was to determine the effect of point discharge of treated industrial and municipal wastewater on the distribution of selected water chemical parameters in the Vistula River in Puławy. The studies were carried out in 2018–2019. Samplings were collected in five sampling points and tested in the hydrochemical laboratory. The obtained data were statistically analysed to investigate differences between the sampling points. The negative impact of wastewater discharge on the water quality in the Vistula was found. However, the pollution level decreased with the flow of the river. The parameters tested at measurement point located 1200 m below the discharge approached the values recorded above the sewage outfall. The presented observations of changes in the concentration of pollutants indicate the self-purification capacity of a river. However, for each watercourse flowing through urbanized areas, it is an individual feature. It depends on a number of factors and requires regular monitoring studies taking into account hydrochemical analysis of watercourses.

Opis:
Pollution migration is the main problem of the landfills that have been located, installed and operated without meeting basic environmental protection requirements. Undertaking effective reclamation treatments is conditioned by a good recognition of the object and its close and distant surroundings. The purpose of the work was to determine the potential hazard to the soil and water environment, based on selected factors, in the vicinity of a closed waste landfill at Głębocka Street in Warsaw. In the soil samples taken at the site from various depths, high concentrations of chlorides, EC, ammonium nitrogen and phosphates were found. Furthermore, the high ammonium nitrogen content correlated with the scent of ammonia, and the content of phosphates with the scent of organic compounds. These pollutants testify to the progressive decomposition of substances occurring in the mass of littering waste, which may pose a serious threat to groundwater. The landfill is also a potential geotechnical hazard because it is a dynamically changing object that can change stability, create caverns and landslides.

Opis:
Reducing the emission of pollutants emitted from motor vehicles, and now also in greenhouse gas emissions, is a result of European Union policy. Vehicle design changes are just one way of reducing emissions of harmful substances and greenhouse gases. The second way is to change the type of fuel, by which the vehicle's engine is powered, that is the substitution of conventional fossil fuels derived from crude oil, such as gasoline or diesel fuel by so-called renewable fuels, for which the CO2 emissions are measured not only in the engine exhaust system, but also by analysis "from the source to the wheel" WTW (Well-to-wheel) - is much smaller. As part of this task the Directive 2009/28/EC introduced for all Member States to the use of renewable energy, biofuels, alternative fuels to a certain extent share of the energy and conventional fuel by 2020. This paper presents the results of measurements of emissions on the dynamometer with a diesel engine powered by six kinds of mixtures of diesel oil and rapeseed oil methyl ester (RME) – with esters containing 0 (clean diesel), 20, 40, 60, 80 and 100 (pure rapeseed oil methyl esters)% in the fuel. We analysed the reasons for the impact of changes in fuel composition on selected limited exhaust components. We found, that the addition of esters of rapeseed oil to the diesel fuel can be a reason of reducing the emissions of CO, CO2, and THC in the exhaust gases of tested engine and increased emissions of NOx and PM.

Opis:
In order to reduce the influence of wastewater from enterprises on the environment extreme relevance is gained by improvement of the monitoring system at each stage of technological process. A new tool is calculation of the polluting substances concentration is suggested to be entered into the monitoring system on the basis of determination of material balance of technological process of production that will allow prediction of qualitative and quantitative composition of sewage for the selected period. The system can be used in any enterprise, but the example with all calculations is given for the Mykolaiv Branch of "SUN InBev Ukraine" which became the object of research. The scope of the study covered the process of wastewater formation of the enterprise. Realization of tasks demanded the use of general scientific methods: analysis, synthesis, systematization and generalization in the course of studying of the corresponding literature on the research subject; modelling, formalization, comparison - at drawing up the calculation scheme of concentration of the polluting substances in sewage; supervision - during studying the technological scheme of production; and also methods of mathematical data processing in MS Excel.

Opis:
The mining activities carried out within the area of Ostrava City are responsible for at least six mine dumps of loose materials arising as wastes from mining of mineral resources. In the past there were difficulties with efficient separating of waste rock and tailings from coal and thus high amounts of coal substance remained in the waste, thus being prone to self-ignition. The thermal activity in dumps is responsible for many hazardous substances that pollute the environment and harm human health in the surroundings. Analysing the occurring pollutants in Ema Dump (Czech Republic) using the GC chromatography method, concentrations of CO2 and CH4 were determined in three sampling points during three measurements executed from January to March 2016. The highest measured concentration of CO2 in Ema Dump was 20 722 ppm. The top concentration of CH4 in Ema Dump was 707 ppm. The monitoring of SO2 in Ema Dump was carried out between April 2015 and January 2016. The final concentrations were identified using two measuring methods, namely the thorin method and the method with methylsulfonazo III as an indicator in dependence on different gas flow rates (1.5–3.0 l min-1) during sampling. The measured concentrations of SO2 ranged from 7.21 to 31.50 mg m-3, while the top concentration was taken in January 2016.
Działalność górnicza związana z wydobyciem węgla, prowadzona na rejonie miasta Ostrawa obejmuje poza działalnością górnicza sześć składowisk odpadów górniczych W przeszłości występowały trudności utrzymywaniem w odpadach niskich zawartości węgla zatem w odpadach pozostały znaczne ilości substancji węglowej, podatnej na samozapłon. Aktywność termiczna w wysypisk jest odpowiedzialna za emisję wielu substancji niebezpiecznych, które zanieczyszczają środowisko i szkodzą zdrowiu ludzi w okolicy. Analizując zanieczyszczenia występujące na składowisku Ema (Czechy), stosując metodę chromatografii GC, określono stężenia CO2 i CH4 w trzech punktach poboru prób, podczas trzech pomiarów wykonanych w okresie od stycznia do marca 2016 r. Najwyższe zmierzone stężenie CO2 na składowisku Ema wynosiło 20 722 ppm. górne stężenie CH4 wyniosło 707 ppm. Monitorowanie zawartości SO2 na składowisku Ema przeprowadzono w okresie od kwietnia 2015 r. do stycznia 2016 r. Końcowe stężenie SO2 określono z wykorzystaniem dwu metod wykorzystując jako wskaźnik thorin i methylsulfonazo III dla natężenia przepływu gazu (1,5–3,0 l min-1) podczas pobierania próbek. Zmierzone stężenia SO2 wahały się od 7,21 do 31,50 mg /m3, najwyższe stężenie zostało stwierdzone w styczniu 2016 roku.

Opis:
The article is dedicated to development of the methodological approach to determine the most effective ways and areas of investments use aimed at reducing the negative impacts of pollution. This takes into account the reality that the level of pollution is different for different areas (regions), and the degree of negative impact is due to two main factorsvolume of gas emissions and the number of residents living in these territories. Taking into account the lack of quantitative laws regarding the impact of pollution on human lives the expediency to limit some qualitative considerations that significantly contribute to the solution of the problem are developed in the article. The paper develops analytic approach, which is based on establishing the parameters that characterize the essence of the developed phenomenon. The state of air pollution in particular is seen as the main factor that significantly affects the residents’ life quality. At one and the same degree of negative pollution, its effect will depend on the number of residents living in the area. As our research continues with the assessment of air pollution reduction state, where two indicators were developed – harmful gas components in the air and population density in the area. Based on the hypothesis of parabolic type, the corresponding functional relation between the parameters proves, that the product of assumed parameters determines the priority of pollution reduction in some areas. The conducted proposed approach to interpretation of dust pollution on the example of regions of Poland is developed.

Opis:
Objectives The authors aimed to evaluate whether blood cadmium (B-Cd), lead (B-Pb) and mercury (B-Hg) in children differ regionally in 9 countries, and to identify factors correlating with exposure. Material and Methods The authors performed a cross-sectional study of children aged 7–14 years, living in 2007–2008 in urban, rural, or potentially polluted (“hot spot”) areas (ca. 50 children from each area, in total 1363 children) in 6 European and 3 non-European countries. The authors analysed Cd, Pb, and total Hg in blood and collected information on potential determinants of exposure through questionnaires. Regional differences in exposure levels were assessed within each country. Results Children living near industrial “hot-spots” had B-Cd 1.6 (95% CI: 1.4–1.9) times higher in the Czech Republic and 2.1 (95% CI:1.6–2.8) times higher in Poland, as compared to urban children in the same countries (geometric means [GM]: 0.13 μg/l and 0.15 μg/l, respectively). Correspondingly, B-Pb in the “hot spot” areas was 1.8 (95% CI: 1.6–2.1) times higher than in urban areas in Slovakia and 2.3 (95% CI: 1.9–2.7) times higher in Poland (urban GM: 19.4 μg/l and 16.3 μg/l, respectively). In China and Morocco, rural children had significantly lower B-Pb than urban ones (urban GM: 64 μg/l and 71 μg/l, respectively), suggesting urban exposure from leaded petrol, water pipes and/or coal-burning. Hg “hot spot” areas in China had B-Hg 3.1 (95% CI: 2.7–3.5) times higher, and Ecuador 1.5 (95% CI: 1.2–1.9) times higher, as compared to urban areas (urban GM: 2.45 μg/l and 3.23 μg/l, respectively). Besides industrial exposure, traffic correlated with B-Cd; male sex, environmental tobacco smoke, and offal consumption with B-Pb; and fish consumption and amalgam fillings with B-Hg. However, these correlations could only marginally explain regional differences. Conclusions These mainly European results indicate that some children experience about doubled exposures to toxic elements just because of where they live. These exposures are unsafe, identifiable, and preventable and therefore call for preventive actions.

The recovery range was found between 30% and 70%. The study was carried out on two, three, and four wheelers. Biodiesel samples tested in the study were synthesized indigenously from different starting raw materials and analyzed for PAHs concentration in the exhaust on a Honda genset (EBK 2000AC Model). Biodiesel samples were blended with diesel in different ratio (25:75, 35:65 and 45:55) to investigate the exhaust behavior. Biodiesel was blended with Diesel the concentration of almost all PAHs reduces in comparison to pure Diesel exhaust. B(a)A and B(a) P was the common PAH found in higher concentration in almost all fuels. FTIR results indicate esterification of vegetable oil and NMR results indicate a complete conversion of oils into biodiesel.

The pollution of urban soil with heavy metals caused by traffic activity is increasingly becoming a great threat to human health and environmental quality. This paper presents results of research of lead (Pb) and cadmium (Cd) distribution in land on playgrounds situated near busy streets in Cracow (Poland). Samples of sand and soil were collected from the most top layer (0–10 cm). Concentrations of examined metals are: Pb from 6.80 to 54.04 mg/kg and Cd from 1.60 to 2.61 mg/kg, respectively. The highest concentrations were found in sampling points near the busiest roads, and are particularly visible in the case of lead concentration in soil samples. For sand samples, metal concentrations are much lower. Although the results have not determined a high degree of soil’s contamination, they indicate the problem of the children’s exposure to toxic metals. Urban soil should be monitored particularly in such special places as playgrounds.

Opis:
One of inorganic sorbents used in water treatment technology is activated alumina. It is recommended by the European Commission to remove inorganic impurities, such as arsenic, fluoride, selenium and silicates. The adsorbent is usually applied in a granular form, under flow conditions. It can become absorbent material, increasingly used due to the presence of arsenic beside iron and manganese in groundwater intakes. The aim of the study was to evaluate the effectiveness of groundwater treatment in the technological system containing adsorption on activated alumina. The experiment was performed on test model CE 581 manufactured by G.U.N.T. Hamburg, in which four treatment stages can be extracted. The first stage is used in a gravel filter of grain size 1–2 mm, in the second sand filter of grain size 0.4–0.8 mm. The third and fourth phase includes two adsorbers. The first adsorber comprises activated alumina (Al,sub>2O3) and the other comprises a granular activated carbon. The study was conducted at different speeds of filtration: 5, 10 and 15 m/h. In the raw water samples and the purified water samples after each treatment step the following parameters were determined: pH, O,sub>2 concentration, electrolytic conductivity, SO42-, concentration, NO3- concentration, PO43- concentration, Cl- concentration, color, turbidity, iron and manganese concentration, CODMn, total hardness, calcium hardness, magnesium hardness, content of dissolved substances. The conducted research indicates that optimum filtration rate for most pollution is 15 m/h. Moreover, the presence of activated alumina has contributed to increasing the efficiency of nitrate (V) and phosphate (V) ions removal.

Opis:
Changes in the magnetic susceptibility of topsoil, especially in urban areas, are greatly affected by the deposition of anthropogenic metallic dust arising from industrial activities, the burning of fossil fuels, car wear, and tyre abrasion. In this study, magnetic susceptibility measurements were carried out in vertical soil profiles of 30.0 cm depth from the surface at 10.0 cm intervals in about 431 locations within the Abuja metropolis with a view to investigate the penetration ability of magnetic pollutants in the ground. From the obtained data, 3-D surface contour maps were plotted for different depths. The results show a magnetic susceptibility decrease from the surface down the ground to the depth of 30.0cm; most of the recorded susceptibilities were of an anthropogenic origin rather than pedogenic activities. This indicates that the anthropogenic dust depositions are mostly a surface phenomenon and may therefore not pose a risk to groundwater aquifers and near surface wells.

Badania nad wpływem zbiornika retencyjnego w ochronie jezior przed spływem zanieczyszczeń ze zlewni rolniczych prowadzono w okresie dwóch lat hydrologicznych 2005/2006. Do badań szczegółowych wytypowano zbiornik retencyjny znajdujący się w dolinie końcowego biegu strugi Sząbruk położonej w północno-wschodniej Polsce, w makroregionie Pojezierza Mazurskiego i mezoregionie Pojezierza Olsztyńskiego. Badana zlewnia składa się z części leśnej i rolniczej. W dolnej części strugi Sząbruk znajduje się zbiornik retencyjny zamknięty groblą i mnichem. Odpływ ze zbiornika kierowany jest końcowym odcinkiem strugi Sząbruk do Jeziora Wulpińskiego. W wyniku przeprowadzonych badań stwierdzono, iż średnie stężenie suchej masy, substancji mineralnych oraz ChZTCr w wodach odpływających z badanych zlewni cząstkowych zależało od sposobu i intensyfikacji użytkowania, w zlewniach rolniczych były wyższe niż w odpływie ze zlewni leśnych. W wyniku przepływu wody przez zbiornik retencyjny następował spadek stężenia suchej masy, substancji mineralnych oraz ChZTCr względem zlewni rolniczych, będących przyczyną zanieczyszczeń obszarowych. Ładunek suchej masy, substancji mineralnych, ChZTCr odprowadzany z obszaru zlewni był uzależniony od sposobu jej zagospodarowania. Największy odpływ ładunku badanych wskaźników z jednostki powierzchni stwierdzono w zlewni rolniczych. Zbiornik retencyjny tworzy skuteczną barierę dla zanieczyszczeń obszarowych, redukując ładunek suchej masy o 91%, substancji mineralnych o 92%, ChZTCr o 88%.
The effect of a retention reservoir in lakes protection against the runoff from agricultural catchments was studied during two hydrological years 2005/2006. Detailed investigations were carried out on a retention reservoir situated in a valley, in the lower course of the Szabruk stream in north-eastern Poland, in the Masurian Lakeland macroregion and the Olsztyn Lakeland mesoregion. The catchment area of the Szabruk stream consists of an agricultural and an afforested part. The retention reservoir located in the lower course of the Szabruk stream is enclosed by a dike and is equipped with an outlet box. The outflow from the reservoir passes through the terminal section of the Szabruk stream to Lake Wulpinskie. The average concentrations of dry matter and mineral matter, and the average values of CODCr in the outflow from the studied catchment were determined by the type and intensity of land use, and they were higher in the agricultural catchment than in the afforested catchment. The concentrations of dry matter and mineral matter, and the values of CODCr decreased following the passage of the stream's waters through the retention reservoir, compared with the agricultural catchment. The loads of dry matter, mineral matter and CODCr in the outflow from the analyzed catchment were determined by the type of land use. The highest unit loads were noted in the agricultural catchment. The retention reservoir was found to be an effective barrier to pollutants, reducing the loads of dry matter (by 91%), mineral matter (by 92%) and CODCr (by 88%).

Opis:
Magnetic susceptibility measurements remain one of the most reliable methods used to investigate the pollution of both surface and subsurface soil from metallic anthropogenic sources. Most of the geological rocks within the study area increase the susceptibility of the soil; however, knowing the natural background susceptibility of the parent rocks will give an idea of the anthropogenic influence on the susceptibility of the soil. This study was carried out in Kogi State, North Central Nigeria, with the aim of determining the depth of the boundary between the anthropogenic influences on soil magnetic susceptibility from those of a lithogenic origin. Magnetic susceptibility measurements were carried out on 1,760 soil samples, collected from 220 soil profiles at a depth of 80.0 cm and at intervals of 10.0 cm. From the spatial distribution of magnetic susceptibility maps at different depths, the boundary between the basement complex and the sedimentary basin was clearly demarcated. The result further shows the highest magnetic susceptibility values of 350–650 × 10−5 SI, which dominates the surface soil to a depth of 40.0 cm. At the depth of 40–50 cm, the result indicates the combination of a natural anthropogenic influence on soil magnetic susceptibility with an average of 250 × 10−5 SI. Furthermore, no evidence of layering along the depth sections was observed, suggesting that the soil profiles indicate areas mainly covered by anthropogenically influenced susceptibility, which were localized and restricted to commercial places within the state. This study reveals that the average depth of soil affected by anthropogenic pollutants is between 40–50 cm in commercial places and 20–30 cm in other places with less commercial activities.

Opis:
The environment resistance potential is defined as the ability of the landscape to limit the negative pollutant impact consisting a.o.in the limiting, by means of accumulation, of the amount of pollutants circulating in the environment system. In practice, their quantity is contigent on the proporties of the components, which are capable of a relatively long-lasting chemical substance accumulation (thus, above all, the properties of the soil cover). The forecast model of environment changes describes the mechanisms and distribution rate of pollution in the soil profile and the interaction with the functional landscape structure. The methodological assumptions, determining of the real, complex diagnosis of the environment condition and for forecasting of the effects of the persisting anthropopressure and for establishing the necessary measures limiting the progressing degradation. Knowing, even approximatively, the mechanism of the existing changes one can determine the optimal (under circumstances) level of pollutant input, and when its limitation is impossible, one can control the use of the environmental potential in such a way as to minimize its negative impact.

Opis:
Rapid socio-economic development and urbanization have contributed to the serious deterioration of air quality in many world cities including Pristina, the capital of Kosovo. Through a data-driven analysis of regulatory intervention, this study attempts to examine the effectiveness of air pollution control regulations that have been implemented in Kosovo between 2010–2021. Our results show that the measures enforced during this 10-year period in Kosovo, and particularly in the capital city, have resulted in the reduction of pollution. The applied methods for this research are the standard ones of the Instituti Hidrometeorologjik i Kosovës (Hydrometeorological Institute of Kosovo). All results showed a decrease of each pollutant over the ten years. These changes strongly indicated that the origin of the pollution was traffic and anthropogenic activity, while the power plant was considered to be a less significant source of pollution. The basic pollutants of air quality in Pristina are particulate matters (PM2.5 and PM10), ozone and nitrogen oxide.

Opis:
It's common to find petroleum substances, especially polycyclic aromatic hydrocarbons, in the sewer or haw waters of the urban environment. These polluted waters flows directly to the urban sewer system in the form of a wastewater. Examination of such events has been carried out in the city of Slupsk, the Pomorskie Voivodeship. In order to limit the polluted surface and rain water flow to the salmon river, twelve oil separators has been deployed around the city. First phase consisted of four such deployments. The separators were designed to filter the rain and surface waters. The following efficiency evaluation showed that according to polish law, in any case the PAH limits has not been reached. Evaluation of easily downward suspension samples also showed trace amounts of the substances. In 40 evaluation series (4 separators x 10 series) the limit was exceeded in 13 cases. The average efficiency of the separators was calculated to be 67.5%. For the four previously described separators the efficiency was as follows: Separator 5 and 17 – 80%, Separator 13 – 70%, Separator 14 – 40%.

The raw coal was utilized as adsorbent based on its remarkable adsorption ability of coal slime to organic compounds in the flotation process. This paper mainly investigates adsorption behaviors of benzpyrole (BZP), pyrrole (PR) and benzoic acid (BA) on powdered coal (PC). In the monocomponent solution, the removal efficiencies of BZP, PR and BA reached 85.23%, 55.02% and 24.84% at PC dosage of 20 g/dm3. Adsorption behaviors of three pollutants fitted perfectly to the pseudo-second order kinetics model and liquid film diffusion occupied the largest proportion in rate-limiting step according to the diffusion rates. Furthermore, the influences of pH on adsorption behaviors and competitive adsorption mechanism of three pollutants were also reported.

Opis:
Koncepcja zrównoważonego rozwoju zakłada taki sposób zaspokajania potrzeb współczesnego człowieka, który nie ogranicza możliwości zaspokojenia potrzeb przez przyszłe generacje. Oznacza to, że każde współczesne działanie mające na celu polepszenie jakości życia powinno odbywać się w trosce o zachowanie równowagi przyrodniczej oraz trwałości podstawowych procesów przyrodniczych. Nie da się ukryć, że rozwój gospodarczy pociąga za sobą intensywną chemizację środowiska. Rozwój komunikacji i przemysłu oznacza wzrost emisji spalin oraz wytwarzania odpadów przemysłowych, podnoszenie wydajności produkcji rolnej nieodłącznie związana jest z wprowadzaniem do środowiska substancji chemicznych w postaci nawozów sztucznych czy środków ochrony roślin. Stały wzrost populacji ludzkiej związany z podniesieniem jakości życia to dodatkowo zwiększenie ilości odpadów komunalnych. Wszystkie zanieczyszczenia mogą potencjalnie oddziaływać na organizmy bytujące w danym środowisku, co w efekcie może prowadzić do zaburzenia równowagi w ekosystemach. Aby przeciwdziałać temu zjawisku koniecznością staje się więc stałe monitorowanie wpływu zanieczyszczeń na systemy biologiczne.
Intensive environmental contamination by chemicals caused by human activities makes the monitoring of biological systems response necessary. It is difficult to predict the effects of pollutants basing only on measuring their concentrations in the abiotic environment. Toxic effects of pollutant are determined by its bioavailability for the accumulation in the body. Measurement of bioconcentration of pollutants in organisms is one of the types of biomonitoring. This allows the tracking the distribution of pollutants in the environment, not only allowing the assessment of environmental pollution, but also the real threat posed by these pollutants for the organisms living in this environment. Monitoring of bioconcentration of pollutant in conjunction with the analysis of their physiological effects and trophic relationships in ecosystems allows the prediction of ecological effects of pollution.

Opis:
Biotechnological processes are widely used in environmental engineering. However, a common problem associated with the biological method relating to the removal of certain pollutants from the environment is low solubility in water, which significantly limits the possibility of their biodegradation or washing. Therefore, a growing interest in the application of surfactants, for instance, for the remediation of soil, is observed. Surfactants can significantly influence the removal of pollutants from the environment. Not only do they increase the solubility of hydrophobic compounds, but also aid in their leaching and increase their bioavailability. Moreover, the use of surfactants by leaching of pollutants is relatively cheap compared to the extraction with organic solvents. As in the case of bioremediation of soil, the use of surfactants could potentially affect the growth of the removal efficiency of hydrophobic pollutants from combustion gases by increasing their bioavailability. This paper presents the results of preliminary laboratory studies using β cyclodextrin in purifying of air contaminated by toluene vapors by biofiltration. In the assumed concentrations (1, 2, 3 g/dm3) the positive effect of cyclodextrin on toluene biofiltration was not observed.

Opis:
Mineral sequestration is one of the methods of reducing the anthropogenic emission of CO2. Sequestration of CO2 via mineral carbonation is an ecologically safe method, since the ongoing processes result in products that are thermodynamically stable and neutral to the environment, in the form of carbonates, while the process of mineral carbonation through CO2 bonding in natural mineral resources and concrete is a phenomenon occurring in nature. At the same time, it may be used to reduce the leachability of impurities from waste. The employment of mineral carbonation in order to reduce the leachability of impurities from fly ash seems particularly interesting, as, at present, the ash is scarcely used in economy. Thus, CO2 reduction may be limited as well as leachability of impurities from waste, partly solving the problem of its deposition. The literature on leachability of fly ash after its prior mineral carbonation has been reviewed in the paper. The conditions of performing the process of carbonation by different authors have also been presented. The authors have shown the findings on three selected fly ash types from Polish power industry prior to and after their carbonation. The process of carbonation was carried out at a research station assembled specially for this purpose. The impact of mineral carbonation use on leachability of impurities from ash-aqueous suspensions has been presented. In the paper, the findings on leachability of the following chemical impurities have been revealed: Zn, Cu, Pb, Ni, As, Hg, Cd, Cr, Cl-, SO4 -2 from ash-aqueous suspensions, with compositions based on fly ash from hard coal combustion in Jaworzno and Lublin heat and power plants, from lignite combustion in Bełchatów power plant, as well as pH and chemical oxygen demand (COD) in leachates from ash-aqueous suspensions. The insertion of CO2 caused the reduction of leachability of Zn, Cu, Cr in case of all the three researched ash types. The obtained results have been compared with the requirements of PN-G-11011 standard 'Materials for solidified stowage and groutingof cavings' in the Regulation of Minister of Environment, 29th November 2002, on requirements to meet while entry to waters or soil of sewage, as well as on substances specifically harmful for the water environment and the Regulation of Minister of Environment, 27th November 2002, on conditions that surface waters employed as the sourceof drinking water are subject to. The findings on leachability only in certain cases do not meet the requirements of PN-G-11011 standard as well as the previously mentioned Regulations. The method of mineral carbonation is particularly interesting, since it may be used not only for CO2 sequestration, but also for limiting the leachability of ash from waste incineration, which may soon become, due to its amounts caused by increasing waste mass, the waste difficult to manager and which, above all, will be landfilled. This article is a preliminary publication signalizing the idea of leaching stabilization by mineral carbonation.

Steroid compounds are a kind of pollutants which are increasingly more frequently found in environmental samples. Due to the ever more increasing level of such pollutants and their biological activity, they are of interest to analysts. Our study involved the development of a simple and fast method for the assay of dutasteride in treated industrial waste water using high-performance liquid chromatography. As the steroid concentration in water is much lower than the limit of detection of the UV detector used, the compound assayed in the test water was pre-concentrated using solid-phase extraction. Our procedure has high accuracy and a precision of 2.6%, and the recovery of the analyte from water is 78.6%. The procedure enables the assay of dutasteride at a level of 2 microg/L in water.

The progress of civilization as well as the growing up process of transformative environment adversely affect individual environmental elements in the soil. In recent years the increasing pollution of the atmosphere causes more and more interest in the science of the substances contained in it and merge back to the surface of the Earth. Of great importance for the environment have the substances contained in the water drainage, as in the form of dissolved very easily reach the individual environmental elements causing their contamination. Strong acidification most soils in Poland is the main cause of weak download main nutrients in soils, and low yields. Part of important plant micronutrients: iron, copper, zinc, manganese, cobalt/an acidic soils are more available In soils acidic phosphorus being introduced in mineral fertilisers is associated with aluminum and iron, in forms not available for plants. The low pH of the soil inhibits the oxidation of ammonium nitrogen (NH4 +) to nitrate (NO3 -), and at the same time, poorly developed root system is not able to efficiently downloadion nitrate from the soil. The result is outside the range of the washing of nitrate nitro gen contamination of groundwater and is followed by the root system. The purpose of the work was to determine the pH of precipitation and atmospheric.

Opis:
The paper presents the results of field and laboratory studies aimed at studying the processes of oil transformation in the soil under the influence of natural biological processes during a two-year period on artificially created old spills. The soil of the study area was characterized as meadow. The high toxic effect of oil was confirmed, which was expressed in the complete extinction of soil flora and fauna. Despite the low oil content in the soil (less than 5%), soil self-purification processes were not observed. Moreover, the high sorption properties of the soil, the violation of the water regime and the lack of aeration led to the “conservation” of oil and significantly slowed down the natural processes of its biodegradation. This was confirmed by a slight change in the content of oil products a year after the start of the experiment, as well as the presence of free oil in the pore space of the studied soil.

Opis:
At the time when Poland joined the European Union, the quality of the air in the country was far from the European standards. At the moment, the level of certain pollutants in the air is still high, which may result in legal proceedings of the European Union bodies against Poland, and consequent substantial financial charges. What is worse, it is estimated that as many as 45,000 Poles die every year due to air pollution. That is why NIK has decided to conduct an audit aimed at evaluating the activities of public entities undertaken with a view to improving the quality and protection of the air in the period between the year 2008 and the first half of the year 2014. The audit covered: the functioning of air monitoring, the development of air protection programmes by individual bodies of regional self-governments and the performance of tasks set out in these programs by competent self-government bodies, the financing of tasks related to air protection by regional funds for environmental protection and water management, as well as the coordination of activities and cooperation of organisational units with regard to the implementation of protection related measures. The audit was carried out in five regions (Małopolskie, Mazowieckie, Opolskie, Pomorskie and Śląskie), and it covered 25 auditees.

Opis:
This study addresses estimation of emission rates and concentrations of SO2, CO and NO2 gases emitted from Daura Refinery (DR), Daura Power Plant (DPP) and South of Baghdad Power Plant (SBPP) by calculating the fuel discharge. The estimations were made by using the Gaussian plume model of dispersion at distances within 10 km from the pollution source for January, April, July and October 2017 under two stability conditions, slightly stable and moderately unstable. The effect of wind speed and direction as well as the ambient temperature of the surrounding air on the dispersion and transmission of air pollutants were also investigated. It was found that the unstable conditions are better for dispersing out atmospheric pollutants. The results showed that Zafarania District was the most affected by pollutants emitted from DR and BSPP while Daura District was more affected by DPP due to the prevailing wind direction. It was also found that an increase in wind speed leads to a decrease in the concentration of pollutants. The concentration of pollutants is inversely proportional to the height of the chimney, the speed of the gas leaving the chimney, while it is directly proportional to the diameter of the chimney. DPP has higher emission rates than DR and SBPP while at the surface level, the pollutants concentrations emitted from DR are greater than those emitted from DPP and SBPP.

Opis:
The present work defines main conception of modern, efficient and ecologic two-stroke engine. It indicates the scope of necessary modifications that have to be made in typical four-stroke engine to prepare it to work in two-stroke mode. Taking into account some limitations (especially in valve train design) authors performed several analyzes in order to check the possibility of proper scavenging process and obtain main engine characteristics. The paper contains description of simulation approach and selected mathematical models that was applied in carried over analyzes. The results of foregoing simulations, which were obtain taking advantage of GT-Power software should be considered as preliminary since several parameters have to be defined during research and 3D simulations. In order to expose advantages of modern two-stroke engine a simple comparison of it and its predecessor was performed taking into consideration BSFC maps. The objects of simulation were fluid flow, scavenging and combustion. This comparison indicates that proposed two-stroke engine achieve significantly less break specific fuel consumption (up to 27 g/kWh drop). Paper presents diagram of new type two-stroke engine with poppet valves, which is probably the most feasible layout of two-stroke engine, and GT-Power model of simulated single-cylinder engine based on four-stroke single cylinder engine.

Opis:
The aim of the research was to show which theoretical statistical distribution best reflects and describes the variability of pollutant concentrations in treated sewage, discharged from small sewage treatment plants, characterised by a value below 2000 PE. The statistical analysis additionally takes into account the influence of the number of measuring sequence data on the shape and level of the distribution fit. The data for the research were obtained from three small sewage treatment plants, operating in the Lesser Poland, 10, 11 and 14 km from Kraków. Due to their size, these facilities are included in the group of treatment plants below 2000 PE. The research was conducted for 10 years. In the statistical analysis, 20-, 40-, 60- and 80-element data series were used, including the values of biochemical oxygen demand (BOD5), chemical oxygen demand (CODCr) and total suspended solids (TSS), determined in samples of treated wastewater. Two commonly used tests, Kolmogorov-Smirnov λ and Pearson’s χ2 test were used to assess the fit of the theoretical statistical distribution to the empirical data distribution. Statistical analysis showed that the studied communities were characterised by an asymmetric, right-oblique distribution. Most often, the empirical distribution of the analysed measurement sequences was consistent with the Fisher-Tippett distribution. On the basis of the χ2 test, this distribution was described by a total of 31 out of 36 analysed groups at the significance level of a = 0.05. Other distributions that often describe the analysed empirical data are: Gamma, log-normal, Chi-square, and Weibull. The common feature of these distributions is usually asymmetry, right oblique. The skewness value ranges from 0.15 to 1.69.

Opis:
The study presents variation of wastewater inflow and its components during a year. We considered a situation with and without precipitation. Two renovated wastewater treatment plants were selected to analyse the available parameters and relation between them. Both wastewater treatment plants served to treat domestic and industrial wastewater with similar characteristics. One of them is only for the town purposes; second one serves for the surrounding villages. The relation between the concentration of pollutants and a flow of wastewater is very low. The correlation and a coefficient of the determination between pollutants were over 0.5.
