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 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.

Opis:: 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:: 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:: 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, SO₄^2-, concentration, NO^3- concentration, PO₄^3- 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:: 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:: Usuwanie trwałych zanieczyszczeń organicznych (TZO) z różnych komponentów środowiska jest istotnym problemem, któremu aktualnie poświęca się wiele uwagi. Konwencjonalne metody stosowane do ich eliminacji często są nieskuteczne i wymagają dodatkowych rozwiązań. W tym celu prowadzone są badania nad możliwością zastosowania zaawansowanych metod utleniania, do których zalicza się również fale ultradźwiękowe. Praca zawiera ocenę możliwości zastosowania metody sonochemicznej do utleniania ftalanu dibutylu (DBP). Przedstawiono wyniki badań dotyczące skuteczności działania pola ultradźwiękowego o stałej częstotliwości 20 kHz. Badano wpływ pH roztworu, czasu nadźwiękawiania i amplitudy drgań na przebieg procesu rozkładu. Do izolacji analitu wykorzystano ekstrakcję do fazy stałej (SPE). Ocenę stopnia obniżania zawartości DBP dokonano na podstawie oznaczeń ilościowych techniką chromatografii gazowej sprzężonej ze spektrometrią mas (GC-MS). Przeprowadzone badania wstępne udowodniły skuteczność zastosowania ultradźwięków do usuwania ftalanu dibutylu.
Removal of persistent organic pollutants (POPs) from various components of the environment is an important issue, which currently much attention is paid to. Conventional methods used for their elimination are often ineffective and require additional solutions. For this reason, studies are being conducted on the possibility of using advanced methods of oxidation, which also includes ultrasonic waves. The work includes an assessment of the applicability of the sonochemical method to the oxidation of dibutyl phthalate. Presents results of tests on the effectiveness of the ultrasonic field with a fixed frequency of 20 kHz. The effect of pH, sonication time and amplitude on the process of decomposition were investigated. To the isolation of analyte was used solid phase extraction (SPE). The degree of reduction of dibutyl phthalate was determined using gas chromatography coupled with mass spectrometry (GC-MS). Preliminary studies have shown the efficacy of the use of ultrasound to remove of dibutyl phthalate.

Opis:: A popularity café in Baghdad city was chosen to measure the dispersion of nitrogen dioxide (NO₂) and carbon monoxide (CO) as examples of the Indoor Air Pollutants (IAPs) which are considered a significant environmental problem. The aims of this research were, firstly, to measure the variation of NO₂ and CO concentrations; secondly, to examine the effect of the seasonal variation of indoor temperature (°C) and relative humidity (%) on the dispersion of both NO₂ and CO and finally to compare the results with those of the global standards. The volume of café was about 360 m³ and the number of smokers was about 25-35 smoker/day. This work was divided into two parts where the first part includes the experimental work which comprised the measurement of NO₂ and CO by GIGs devices. It was lasted about five months commencing from November 2017 to March 2018 and the readings were taken during two intervals at partial time and during peak time. The second part includes the analysis of obtained results and compared the results of those of the global standards for the Indoor Air Quality suggested by WHO, EPA, and European criteria in order to achieve the goals of this work. The results from this research have highlighted a clear increase in the concentrations of NO₂ and CO along with the growing numbers of smokers. Furthermore, the concentrations of NO₂ and CO were close to some global standard values of short-term exposure at peak time.

Opis:: The paper discusses the issue of removing persistent organic pollutants (POPs) from wastewater, especially the polycyclic organic hydrocarbons (PAHs). The results obtained in literature studies indicate that the commonly employed traditional methods of wastewater treatment are not always efficient in eliminating the hardly bio-degradable pollutants. Therefore, extensive research is being conducted on the application of efficient POPs removal technologies. One of the considered variants involves incorporating advanced oxidation processes (AOP) into the wastewater treatment systems based on the biological processes. These include the reagentless methods, e.g. the processes involving ultrasounds and hydrodynamic cavitation. On the basis of the author’s own studies conducted in a laboratory system comprising a static cavitation reactor, the possibility of applying hydrodynamic cavitation for the decomposition of PAHs was evaluated on the basis of model solutions of anthracene and phenanthrene. It was shown that the employed advanced oxidation process with hydro-cavitation has a significant impact on reducing the concentration of the considered PAHs. It was confirmed that the degradation degree of a substance depends on the intensity and the course of the cavitation process. The energy efficiency of the conducted process was analyzed as well and expressed as the ratio pertaining to the amount of the degraded compound to the electric energy supplied to the system.

Opis:: The work evaluates the effect of anthropogenic pollutants on the quality of water in Lake Bialskie (51º32’07” N 23º00’55” E) and its catchment basin. Samples of water were taken from the lake (4 sampling points) and from wells dug within the catchment basin. The quality of water was analysed in May, June, August and November 2015. In the wells only in single cases was the level of chemical pollution found to exceed drinking water standards. However, in all samples the standard content of manganese was exceeded. In waters from the lake the concentrations of total phosphorus, which can contribute to eutrophication were recorded above the standard level. Both in waters from the lake and from the well a large count of meso- and psychrophiles and Coli and faecal coliforms as well as faecal Enterococci was found, which points to a high degree of contamination of the analysed waters with anthropogenic faeces. The phenomenon was observed to intensify in summer months, which can be associated with increased tourist traffic around the lake in this period.

Opis:: Ciągłe zmiany w środowisku wynikające z zaspokajania ciągle rosnących potrzeb ludności mają poważne konsekwencje. Coraz częstsze zjawiska powodziowe, pogorszenie jakości wód powierzchniowych i zwiększające się zanieczyszczenie mórz są w dużym stopniu skutkiem działalności człowieka. Rosnący udział powierzchni uszczelnionej przyczynia się do zwiększenia zarówno stopnia zanieczyszczenia, jak i ilości wód opadowych, a w konsekwencji ładunku zanieczyszczeń. Celem pracy było określenie szacunkowego ładunku zanieczyszczeń biogennych dopływających do Morza Bałtyckiego z obszaru zlewni Potoku Oliwskiego, jednego z cieków przepływających przez teren miasta Gdańsk. W opracowaniu przedstawiono wyniki badań jakości wody Potoku Oliwskiego, jednego z największych gdańskich odbiorników wód opadowych ze zlewnią o powierzchni prawie 29 km². Próbki wody pobierano w sześciu punktach (trzech w zlewni naturalnej i trzech w zurbanizowanej) podczas pogody bezopadowej i po wystąpieniu epizodu opadowego. Oznaczono stężenia i obliczono ładunki roczne związków biogennych odprowadzanych do Zatoki Gdańskiej. Największy ładunek azotanów (V) i fosforu całkowitego odprowadzany jest latem i wynosi odpowiednio 4 tony NO₃^- w przeliczeniu na rok i prawie 2 tony P_og rocznie. Ortofosforany odprowadzane są głównie jesienią, a ich roczny ładunek wprowadzany do Morza Bałtyckiego to prawie 4 tony. Większość substancji biogennych pochodzi ze zlewni zurbanizowanej, dlatego należy w tym obszarze zlokalizować i ograniczyć źródła zanieczyszczeń.
Flood events, worse condition of surface waters, and pollution of sea waters are associated with the anthropogenic changes in the environment. Increasing pollution and the amount of rainwater – raise the pollution load as a result of increasing the built-up area. The aim of the study was to investigate the pollution load coming from a catchment in Gdansk to the Baltic Sea by stream. The study presents the results of water quality tests in the Oliwa Stream. It is one of the largest rainwater receivers in Gdansk with a catchment area of almost 29 km². Water samples were collected at six points (three in the natural catchment and three in urbanized catchment). The pollutant concentrations were obtained from the tests On the basis of the results, the loads of biogenic compounds introduced into the Gulf of Gdansk were calculated. The largest load of nitrates (V) and total phosphorus is discharged in the summer and amounts to 4 tons NO₃^-and almost 2 tons of total phosphorus per year, respectively. Orthophosphates are discharged mainly in autumn, and their annual load is almost 4 tons. The majority of biogenic substances comes from the urbanized catchment; therefore, it is necessary to locate and limit the sources of pollution in this area.
