Opis:: The environment is considered an ideal machine, a system in which nothing happens without reason. Every transformation, action and stimulus has consequences that are not always immediately plain to see. It is because the environment is like communicating vessels, or a complex organism, in which everything is interdependent, and the organs work together. Despite the processes’ complexity and intricate yet logical correlations between the elements, it is not a perfect system. Examples are weather anomalies and, in extreme cases, cataclysms. The problem arises when man interferes with the environment. By polluting almost every possible place, he initiates irreversible changes, degrading the environment. This paper presents an analysis of atmospheric air pollution in the town of Supraśl, surface water from the Supraśl river, and soil samples from a selected area.

Opis:: Textile industries are the major source of environmental pollution In terms of quality as well as quantity. The textile industries consume large quantities of water (200 m3/ton of product) out of which around 90% is appeared as wastewater. Textile wastewater contains dye as the major pollutant which is not only recalcitrant but also imparts intense color to the waste effluent. Improper disposal of textile wastewater causes serious environmental problems affecting the aquatic organism adversely. The present study deals with the detailed study of environmental issues and treatment options. The industry generates huge amount of wastewater contains toxic pollutants. Several treatment technologies are using now days with high efficiency and from the present study it was found that advanced oxidation process is very effective in terms of pollutants removal efficiency as well as cost requirement.

Opis:: This paper presents the results of studies which aim was to determine the pollution of the water environment for both methods of preparation for the utilization of sewage sludge in agriculture. The study was conducted in 2008-2012 in lysimeters filled with light sandy soil (clayey sand). During the study variants with equal doses of nitrogen in an amount of 20 g . m-2 (15.7 g per one lysimeter) were supplied to the soil in sewage sludge and in the compost made from the same sludge. These variants were used three times for two species of perennial plants: Miscanthus gigantenus i Sida hermaphrodita Rusby. In a variant of sludge soil fertilizing, it was leached into water environment more than 12% of the applied nitrogen over 5 years of research. In case of compost nitrogen leaching was reduced to 8.1-10.0% of the quantity supplied to the soil.

Tematy:: grey water footprint
water pollution level
catchment
Opis:: According to Hoekstra et al. (2011) the water footprint within a geographic area is defined as the total freshwater consumption and pollution within the boundaries of the area. The grey part of the water footprint refers to pollution and is an indicator of the water volume needed to assimilate a pollutant load that reaches a water body. It is possible then, based on the grey water footprint to estimate if the water available in a river at a particular crosssection will be sufficient to maintain a water pollution level (WPL) below 100%. The crossing of 100% indicates that the waste assimilation capacity has been fully consumed in this particular catchment. In this paper, the grey water footprint from nonpoint source pollution has been calculated based on long-term hydrometrological data for the upper part of a small agricultural catchment (area of 23.4 km2 ) (Zagożdżonka River) in central Poland. Based on land use and the amount of fertilizers applied in the catchment, together with information about the natural concentration of nitrogen and phosphorus in the river, as well as maximum acceptable concentration, the water pollution level has been calculated for actual conditions. The estimation of future runoff decreases for the considered catchment (Banasik, Hejduk 2012) has been applied in order to estimate potential future water pollution levels. The calculation shows that, even when the management practices in this catchment remain as they are, including the current extensive crop production, the WPL of 100% will be exceeded in the year 2033 (for phosphorus) and 2043 (for nitrogen) due only to the decreasing availability of water.

Opis:: The self-purification capacity of river water is an essential indicator for a healthy river. Various organic and inorganic pollutants, both from point sources and nonpoint sources, in most streams in Banjarmasin were beyond the river self-purification capacity, which caused a decrease in the river water quality. This study attempted to identify the river water pollution distribution in the city of Banjarmasin and determined the self-purification points. We used the purposive sampling technique to carry out river water sampling, with criteria for pollutant sources and distance of pollution taken into consideration. By using the trend analysis techniques, we analyzed the parameters concentration to relate it to the range of pollution so that we were able to identify the pollution distribution and determine the self-purification distances. The results indicated that the self-purification process could take place on the river flow in of Banjarmasin even though it did not reach the clean water zone. The river in Banjarmasin requires a longer purification distance so that the self-purification process can run correctly.

Opis:: The Dojlidy Ponds, which include Dojlidy water dam, are located within Bialystok city limits in Podlasie area, Poland. The reservoir with a water surface of 34 ha and average depth of 1.75 m was constructed in 1962 as a result of Biala River damming. The researches were conducted in July, October and December 2014 as well as in March 2015. Each time five test samples were collected from spots located along the reservoir. Water samples were tested for the presence of ammonia nitrogen, nitrite nitrogen, organic nitrogen, phosphates and organic phosphorus. The values of nutrient indicators exhibited high variability during the study period. The highest concentration of nitrite and nitrate nitrogen were observed in July, while the lowest in October – nitrite nitrogen, and in December – nitrate nitrogen. Different situation was observed after the analysis of phosphorus forms – the highest concentrations of organic phosphorus and phosphates were observed in December and the lowest in July. Relatively high concentrations of nitrogen and phosphorus forms identified in water samples were most likely caused by tributaries, due to the pollution from the reservoir catchment. Technical parameters of the object and location of the reservoir have undoubtedly an impact on the tested parameters contents.

Opis:: Water pollution in rivers is still a crucial problem for the countries that use river water as the primary water source. This study aimed to determine the water quality of the Musi river and the content of heavy metals in water, sediment and mussels as well as to predict the water quality of the Musi river in the next five years. The water samples were taken from 18 stations (sampling points) from upstream to downstream to be checked physically, chemically and biologically. Prediction of the river water quality was made using the QUAL2Kw software. The research results show that the Musi River water is categorized as lightly polluted with concentrations of TSS and DO that have passed the threshold. The heavy metals in river water, such as Pb and Cr have also passed the quality standard. The Fe, Mn, and Zn concentrations are pretty high in the sediment. In turn, in mussels, the metals measured were Fe, Cu, and Zn. The prediction results reveal that several values of the river quality parameters will pass the threshold value with the same pattern tendency from each station.

Opis:: The Uszwica river catchment is located in the central part of Lesser Poland province, within Brzeski and Bocheński districts. The river is 61.2 km long, and its catchment area is 322.5 km². It is characterized by forest-agricultural land use and high share of residential areas of both compact (the city of Brzesko) and dispersed nature. In the abiotic terms, the Uszwica in its upper course may be classified as a flysch stream (type 12). From the moment of joining the Niedźwiedź, stream until its discharge into the Vistula at km 151+700 it is a sand and clay lowland river (type 19). Hydrochemical research were conducted in the years 2011 and 2012 at two measurement-control points – one located near the mouth of the river (point 1) and one located about 7.5 km downstream from the city of Brzesko (point 2). Each month 18 water quality parameters were determined and they underwent comparative and statistical analyses. Basic descriptive statistics were calculated for both measurement-control points. Then, they were used to determine the ecological potential of the river and to evaluate water quality parameters with respect to its suitability as fish habitat and eutrophication risk. Significance of differences between the values of individual parameters recorded at different measurement-control points was estimated using non-parametric Mann-Whitney U test for α = 0.05. The same test was used to determine the significance of differences between individual parameters for the winter and summer season at each point. Analysis of the results revealed that water flowing via developed areas (point 2) was significantly less saturated with oxygen and contained higher amounts of suspended solids, organic matter and nutrients, as compared to the section of the river flowing mainly through extensively used agricultural areas. Therefore, the ecological potential of the river was considered good in its lower course and poor upstream from point 2. Disturbances in seasonal concentrations of some biogenic factors indicated high degree of water pollution in the middle course of the Uszwica. However, due to intense self-purification, water quality in the lower course was similar to that in natural conditions. On the entire investigated section of the Uszwica does not meet water quality requirements for salmonids and cyprinids, but the habitats are more favorable near the mouth of the river. Waterassessed at point 2 may be classified as eutrophic due to high concentration of total phosphorus.

Opis:: The research concerned the Wapienica dam reservoir, which is located in the Polish Carpathians, near the city of Bielsko-Biala. The dam closes the flow of water from the 11.1 km² catchment. The forests cover about 90% of the catchment area, while the rest of the catchment constitutes grassland areas. The reservoir has a capacity of 1.05 million m³. The collected water is intended for supplying a water supply system. The catchment is treated as semi-natural, because within its borders the only works related to forest management are carried out. The aim of the research was evaluation of the water quality in this reservoir, including trophic status, based on the analyses carried out in 2015. It was found that the water was of good quality in basic physicochemical terms (e.g. suspension ≤13 mg∙dm^-3,COD_Cr ≤11 mgO₂∙dm^-3, conductivity ≤82 µS∙cm^-1, phosphates <0.05 mg∙dm^-3, nitrates ≤5.1 mg∙dm^-3, dissolved iron ≤0.12 mg∙dm^-3). The contamination with heavy metals was not ascertained, with the exception of the zinc. The assessed sanitary indicators are worse – the bacteria of the Coli group and periodically also enterococci were observed in the reservoir water. The reservoir is not homogeneous in terms of biological production (the trophy degree). It is low in the upper part (oligotrophy generally) and increases in the part near the dam (mesotrophy, also eutrophy). The established presence of dangerous bacteria and symptoms of the reservoir eutrophication are disturbing in the context of the opinion on the purity of uninhabited mountain areas.

Opis:: 1,3,7-trimethylxanthine (caffeine) is an ingredient of coffee, tea, energy drinks, drugs and cosmetics. Generally, it is the most consumed pharmaceutical substance all over the world. Although it is easily metabolized, caffeine is present in wastewaters generated by households. Therefore, its detection in streams and rivers shows that untreated wastewaters are discharged into environment. Determination of caffeine in waterways could be an indicator of their anthropogenic pollution. Rudawa is the river flowing through southern Poland, with the river basin area about 318 km2. It is a left tributary of the Vistula River, with the river mouth located in the Krakow city. Rudawa is one of the drinking water supplies for the city. It provides about 40000 m3 of water per year. Water used as a source of drinking water must be the highest quality. Therefore the river on which drinking water intakes are located is the subject of the special monitoring. Water quality monitoring has always been important on Rudawa river and it continues to be monitored today. The aim of this study has been to check whether the caffeine is present in Rudawa waters, to determine its concentration and localization of potential sources of pollution. Samples taken from the river in twelve selected locations along the Rudawa River and its tributaries have been analyzed. Solid phase extraction combined with gas chromatography-mass spectrometry (GC-MS) has been used. Caffeine isotope 13-C3 in methanol, Sigma Aldrich, has been used as an internal standard. The concentration of caffeine in samples has ranged from 40 to 380 ng/dm3.
1,3,7-trimetyloksantyna (kofeina) jest składnikiem kawy, herbaty, napoi energetyzujących, leków i kosmetyków. Jest najpowszechniej spożywanym farmaceutykiem na całym świecie. Chociaż jest łatwo metabolizowana, kofeina jest obecna w ściekach powstających w gospodarstwach domowych. Wykrycie kofeiny w wodach powierzchniowych dowodzi, że ścieki są bez oczyszczenia odprowadzane do środowiska. Oznaczenie zawartości kofeiny w ciekach może być uznane za wskaźnik ich antropogennego zanieczyszczenia. Rudawa to rzeka płynąca w południowej Polsce o powierzchni zlewni około 318 km2, jest lewostronnym dopływem Wisły, do której uchodzi na terenie miasta Krakowa. Rudawa jest jednym ze źródeł zaopatrzenia mieszkańców miasta w wodę. Dostarcza około 40 000 m3 wody rocznie. Woda wykorzystywana jako źródło wody pitnej powinna być najwyższej jakości. Dlatego jakość wody rzeki, na której zlokalizowane jest ujęcie wody pitnej, powinna być pod szczególnym nadzorem. Monitorowanie jakości wody z rzeki Rudawy zawsze było prowadzone i jest nadal. Celem badania było sprawdzenie, czy kofeina występuje w wodach Rudawy, określenie jej stężenia i lokalizacji potencjalnych źródeł zanieczyszczeń. Pobrano dwanaście próbek wody z Rudawy i jej dopływów oraz przeprowadzono ich analizy metodą ekstrakcji do fazy stałej połączonej z chromatografią gazową ze spektrometrią mas (GC-MS). Zastosowano izotop 13-C3 kofeiny w metanolu (Sigma Aldrich) jako wzorzec wewnętrzny. Stężenie kofeiny w próbkach wahało się od 40 do 380 ng/dm3.
