    The waterbody Kłodnica to Promna as was analysed an example of watercourse located in the densely populated and highly urbanized area of the Upper Silesian Industrial Region. The aim of the study was to assess the risk posed to the aquatic ecosystem by priority substances (Ni, Pb, Cd, Hg) and specific non-synthetic pollutants (Cu, Zn), which are released to Kłodnica river. The analysis of the risk assessment was carried out by comparing the concentration of metals in the aquatic environment to the environmental quality standards and by using M-BAT and Pb Screening Tool which are user-friendly simplified BLM models (Biotic Ligand Model). These tools allowed to assess the potential risks posed by metals such as Cu, Ni, Zn, and Pb for the aquatic environment, taking into account the physicochemical parameters of water that affect the bioavailability of metals in the aquatic environment (DOC, Ca, pH). The results obtained by means of these tools showed that the risk caused by the toxicity of Cu, Ni and Pb has not occurred in any of the analyzed samples. On the other hand, high probability of risk due to the presence of Zn in surface water has been identified in all sampling points. The results of the analysis confirmed that the local conditions in terms of physicochemical water parameters have a significant impact on the risk assessment. The results of this study confirmed that the tools which are simplified version of complex BLM are an important element supporting the monitoring process in urbanized river catchment in the context of the Water Framework Directive requirements.

    The research was carried out in the years 2008-2011 in the loess catchment area in Wielkopole in the Lublin Upland. The purpose of the work was to determine the intensity of water soils erosion and the size of the outflow beyond the water catchment and the selected constituents of matter contained in it. After surface water runoff, quantitative and qualitative inventory of erosion damage was carried out. The quantity of waters from the catchment was also measured, from which samples were taken in order to determine the concentration of soil suspension of nitrogen and its forms as well as phosphorus and potassium. The height and intensity of precipitation as well as the thickness of the snow cover were also monitored and observations of its melting were carried out. The research results prove that the condition of the plant cover determines the amount of erosive damage. Spring crops and root crops poorly protect the soil from erosion, while winter cereals, grassland and forests protect good. The average annual erosive damage in the catchment was: rills - 189 m3km-2, surface runoff - 153 m3km-2, deposits - 128 m3km-2, and soil washout - 0.335 mm. The outflow of water outside the catchment is on average correlated with the amount of precipitation (correlation coefficient r = 49). On the other hand, a very high correlation (r = 0.85) was found between the outflow of water and soil from the catchment. On average, during the year outflow from the catchment were: 7.1 mm of water, 44.85 Mgkm-2 of the soil, 127.2 kgkm-2 N-Nog, 18.2 kgkm-2 P and 145.6 kgkm-2 K.

    Water reclamation works, especially those related to stream maintenance, are necessary wherever their lack may cause a risk to the natural environment, as well as human life and property. This paper presents the assessment of the maintenance costs on natural and regulated streams in the years 2010-2016 in the Poznań district. In the analysed years, the costs for works on streams and water-drainage constructions amounted to an average of 1,214,800 PLN per year, which in terms of a 1km stream is approximately 3,575 PLN/km per year. Higher maintenance costs occurred on the regulated streams, where the average cost of a 1 km stream was approximately 7,042 PLN. Moreover, high costs were noted in the works on unregulated streams, where the average cost was approximately 8,948 PLN. The amount of public funding for the maintenance and current operation was quite insufficient, as it covered only 4.2% of the annual average demand. The positive trend is nearly a 6-fold increase in funds for current maintenance compared to the year 2010, when a flood occurred. The results of the conducted analyses indicate the cognitive need and purpose, as well as the economic importance, to establish water reclamation monitoring, as well as develop the existing IT system for recording water reclamation works and water management in agriculture.

    Nowadays, the use of natural biopolymers in the field of agriculture has increased in order to achieve sufficient yields and quality. Chitosan and its derivatives have a great potential with various applications in agriculture. Minimal research on effect of chitosan oligomers with different molecular weight on growth ornamental plants has been published. Ornithogalum saundersiae is a valuable species, recommended for cultivation in gardens and green areas, as well as for cut and pot plant. This species can also be potentially used in pharmacology. In the experiment, 0.5% solutions of oligochitosan with molecular weights MW 5000 and 100,000 g mol-1 were used for coating Ornithogalum saundersiae bulbs. The biopolymers have been characterized using HPLC method. The results indicated that oligochitosan significantly enhanced the growth attributes, physiological parameters, as well as the weight and numerical coefficient of bulbs. Oligochitosan with MW 100,000 g mol-1 proved best and gave maximum width of inflorescence, number of flowers per inflorescence, stomatal conductance and weight of bulbs over the control.

    A significant number of anthropogenic organic micropollutants are classified as hardly- or non-biodegradable compounds, which may adversely affect on living organisms, including human health. Municipal wastewater and wastewater from various industry sectors are considered as the main source of this type of pollutants. The aim of the conducted study was to develop a method for the removal of selected micropollutants such as diclofenac, octylphenol, anthracene and benzo[a]pyrene from various water streams based on advanced oxidation processes and membrane filtration techniques. The research was carried out on solutions prepared based on deionised water and a model real and real effluent from a mechanical-biological wastewater treatment line. The concentration of micropollutions was 0.5 mg/dm3. Photocatalytic oxidation was applied in the presence of TiO2 in a batch reactor equipped with a UV lamp of 150 W. The post-processing solutions ware subjected to the ultrafiltration process, which allowed for the separation of catalyst particles and the retention of high molecular weight organic compounds occurring in the treated water streams. The membrane filtration process was operated in a dead-end mode at a transmembrane pressure of 2 MPa. For their complete elimination, the second stage of membrane filtration using a nanofiltration membrane was applied. The chromatographic analysis, performed to determine the removal degree of tested micropollutants in the post-processing solutions, indicated their incomplete decomposition in the photocatalysis process and the generation of a significant number of their oxidation by-products. The proposed sequential system, that combines photocatalysis with two-stage membrane filtration, allowed for over 91% removal of micropollutants from water solutions prepared on the basis of deionised water and for a complete removal of the compounds and their oxidation by-products from model and real wastewater effluents.

    The aim of the study is to assess the environmental impact of a shut down industrial waste landfill. A detailed analysis of the quality of groundwater around the landfill in the years 1995-2016 was conducted. Assessment of the status of groundwater in the landfill area was made based on the results of monitoring tests. It includes the measurement of pH, specific electrical conductivity (SEC) and the content of chlorides, sulfates, phosphates, heavy metals: copper (Cu), lead (Pb), chromium (Cr) and a number of other pollution indicators. The analysis confirms that the landfill during the operation did not constitute a threat because of a number of employed security measures and sealing layers. Only in recent years, the industrial waste landfill which is already out of operation has become an extremely serious environmental threat. The results of water analyses from the piezometers clearly indicate that there is a problem of groundwater contamination. There was a significant increase in the value of some of the analyzed indicators (such as chlorides and sulfates), mainly in the piezometers located on the flow line of groundwater in the landfill area. The observed situation is probably a result of damage to the sealing layers and leaching of pollutants from waste deposited in the landfill by rain water.

    The econometric model can be a precise instrument for the analysis of the impact of the natural environment's degradation on fishing economy. This paper aims at analysing the influence of the water quality changes in lake Charzykowskie on the fishing economy. This dissertation present the results of a research on the lake water pollution's impact on fishing economy. The economic-ecological models have been constructed, explaining the changes of economic effects of the lake fishery in the conditions of an increasing water pollution in the epilimnion on the example of the catch of Rutilus rutilus, Abramis brama, Blicca bjoerkna, Coregonus albula, Coregonus lavaretus, Anguilla anguilla and Esox lucius in Lake Charzykowskie. Performed empirical research looked into the influence of the environmental factors on the size of fish catch. Calculations and analysis show clearly that though the habitat factors do influence the catch size of each studied fish species, they do it with different intensity and in various combinations. Both lake water quality and climate factors changes cause measurable effects on fishing industry of lake Charzykowskie. Among all the examined Rutilus rutilus, Abramis brama and Blicca bjoerkna the highest environmental requirements concerning water quality has Blicca bjoerkna. Whereas Abramis brama has slightly higher environmental requirements than Rutilus rutilus. Empirical calculations showed as well that Coregonus albula and Coregonus lavaretus have considerably higher water cleanness requirements than Rutilus rutilus, Abramis brama and Blicca bjoerkna. While when talking about Rutilus rutilus, Abramis brama and Blicca bjoerkna, most water characteristics still rather stimulated these species' development, when it comes to Coregonus albula and Coregonus lavaretus, in general they suppressed their development. The model has also proved quite high habitat requierements of Anquilla anquilla and correctness of the thesis that Esox lucius avoids polluted waters. For endogenous variables climatic factors' influence is significant. This prejudges the itinerancy of Rutilus rutilus, Abramis brama, Blicca bjoerkna, Coregonus albula, Coregonus lavaretus, Anquilla anquilla and Esox lucius catch in lake Charzykowskie. The results of the modelling can be used in managing the fishing economy this lake.

    Public purpose investments constitute a special group among the construction investments. They are generally large and their construction is conditioned by the needs of the local communities. The regulations impose the need to analyze variants of this type of investment and to take into account the solutions that cause the low environmental damage. The analyzed example is a specific object, mainly due to the presence of very large groups of people during sporting events. The analysis of the evaluation criteria should cover different location variants as well as design and construction solutions. The assessment of investment variants in this paper takes into account the specific function of the facility, and the criteria used in the analysis concern such phenomena as pollution and noise reduction, environmental impact, collisions with environmental elements, and the ability to safely park a large number of cars. Due to the large number of factors involved in the procedure, it is necessary to employ effective methods of supporting the decision-making processes. The article describes an example of evaluating variants using multicriteria analysis methods. The obtained results confirmed the usefulness of the proposed procedure.

The results of water analyses from the piezometers clearly indicate that there is a problem of groundwater contamination. There was a significant increase in the value of some of the analyzed indicators (such as chlorides and sulfates), mainly in the piezometers located on the flow line of groundwater in the landfill area. The observed situation is probably a result of damage to the sealing layers and leaching of pollutants from waste deposited in the landfill by rain water.
