Opis:: The article presents the results of a study on multiflora rose, one of the energy crop plants. The yield of aerial parts was determined in a field experiment, and the calorific value and chemical composition of the biomass were determined in laboratory tests. The results were used to calculate the amount of hard coal that can be replaced by multiflora rose biomass and the air pollution emissions from combustion of coal and multiflora rose. Combustion of multiflora rose biomass from an area of 1 ha in place of hard coal with equivalent energy value was found able to reduce emissions of SO₂ by 98.9%, NO₂ by 27.8%, particulates by over 18% and CO by 8.5%. The actual CO₂ emissions from biomass combustion proved somewhat higher than in the case of coal; however, carbon dioxide emitted into the atmosphere during combustion of plant biomass is equal to the amount taken in by the plants during their growing period. Therefore the CO₂ 2 emissions are considered to be zero.

Opis:: Manufacturing units, which use biomass for combustion and co-firing, are obliged to gradually increase the amount of biomass from agricultural sources in place of timber biomass from forests. Many different species of trees that grow on arable land, bushes, grasses or perennials can be used for energy purposes. A huge variety of plants that give biomass useful in the power industry, is connected with a large diversity of physical characteristics (hardness, specific gravity, moisture content, porosity) and chemical composition. It significantly affects not only the calorific value of biomass but also the condition of the boilers in which it is burnt. This paper presents the results of the research concerning the influence of the process of combustion biomass from seven plant species on the boilers fouling on the basis of ash chemical composition. The indicators used for the analysis were as follows: boilers slagging, the tendency of fuel to form impurities, sintering and agglomeration. A significant variation in the content of alkalies was shown that cause the formation of sediment on the boilers heating surfaces. The smallest risk of heating boilers fouling is associated with perennial grasses incineration, especially the ones from the Miscanthus species that contain significant quantities of silicon monoxide, which is responsible for the heating surfaces erosion. The usage of polycarpic plants, such as Virginia mallow or Jerusalem artichoke, may cause pollution deposition and reduce the efficiency of boilers to the greatest degree. Because the biomass of different plant species exhibits the diversity of energy parameters and tendencies to foul boilers, there is a need to select the material to the combustion carefully. Moreover, blends of biomass raw materials (or biomass with coal) should be composed so that they are adapted to the boiler parameters and to the conditions of the combustion process.

Opis:: This paper aims to analyze the variability of the surface and ground water levels in Ambona peatlands. The depth at which the ground water table occurred was studied with reference to the adopted land drainage standards. The studies were carried out in 2009/10–2015/16 for natural and regulated water outflows. The analysis of annual total precipitation suggests that in the analyzed period some years were very wet (2009/10 and 2013/14), some were wet (2010/11, 2012/13 and 2015/16), one year was dry (2014/15) and one year was normal (2011/12). The 7-year average seasonal precipitation amounted to 598 mm, which was 71 mm higher than the average precipitation recorded in 30 years. The level of water in the river under adjustable outflow conditions ranged from 55 to 77 cm. The level of water under natural outflow ranged from 18 to 49 cm. In the area with adjustable outflow, the average draining depth was 47 cm. In the remaining area, not covered by the irrigation system, the draining depth was 64 cm. Additionally, the dynamics of variance in the water level under natural outflow conditions was clearly higher.

Opis:: The aim of the work is to present the current state of water and wastewater management in the municipalities where the Polesie National Park (PNP) is located. The PNP is situated in Lublin Voivodeship, in the area of six municipalities: Sosnowica, Hańsk, Urszulin, Stary Brus, Wierzbica and Ludwin. The data used in this paper, were obtained on the basis of the surveys conducted in these municipalities in 2016 by the Department of Environmental Engineering and Geodesy of the University of Life Sciences in Lublin. In the analyzed communes, there was a very large disproportion between the usage of sewerage and the water supply network. It has been shown that 79.1% of the inhabitants living in the afore-mentioned communes used the water supply network and only 22.5% of them used sewerage. In the discussed communities there are 9 collective, mechanical and biological wastewater treatment plants with a capacity of over 5 m³•d^-1. On the farms located in the scattered areas, which are not connected to the sewerage, wastewater is discharged mainly to the septic tanks. In four out of the six analyzed municipalities, there were 2345 septic tanks registered. Domestic sewage from some farms is purified in household wastewater treatment plants (395 pieces). The plants with the drainage systems are prevalent (84.9%), which may contribute to the groundwater quality degradation. In order to protect the natural environment within the communes that form the PNP, it is necessary to undertake the actions that will contribute to the improvement of the current state of water and wastewater management. While solving the existing problems related to water supply and wastewater treatment, it is strongly required to adhere to the principle of sustainable development and use highly effective systems in order to ensure that the ecological effects are appropriate.

Opis:: The aim of this paper is to present the current state of water and sewage management in the communes where the Roztocze National Park (RNP) is located. The park is located in Lubelskie voivodship, in the territory of four communes: Zamość, Zwierzyniec, Adamów and Józefów, while its buffer zone is located in the communes of Krasnobród, Tereszpol and Szczebrzeszyn. The paper uses data from surveys conducted in these municipalities in 2016. On average, 68.9% of the population used the water supply system in the municipalities surveyed, while 33.4% of the inhabitants had the possibility of discharging sewage to the sewerage system. In the area of the communes, there are 10 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m³·d^-1. The households which are not connected to the sewage network discharge wastewater mainly to non-return tanks. Four out of the seven surveyed communities had 64 domestic sewage treatment plants, including 60 systems with infiltration drainage, which do not ensure high efficiency of removing pollution and may even contribute to the degradation of groundwater quality. In order to solve the existing problems in the area of sewage and water management occurring in the communes where the Roztocze National Park is located, it is necessary to further develop collective sewage systems and equip the areas with dispersed buildings with highly efficient, residential sewage treatment plants, e.g. constructed wetlands.

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.
