Opis:
Geothermal waters under national conditions have the status of minerals, which means that their exploitation is carried out in accordance with the provisions of Geological and Mining Law. In the area of the Podhale Basin, one of the boreholes that extracts water of elevated temperature is the Chochołów PIG-1 borehole which constitutes the basis for the functioning of the Chochołowskie Termy recreation complex. The main feature of the waters intake due to the correct functioning of the complex is the stability of temperature and physicochemical parameters. The variability of most important hydrogeological parameters (temperature, SEC, SO42-, Cl-, HCO3-, Ca2+, Mg2+, Na+) with available data base were chosen for the analyzes. These parameters determine economic viability and proper conditions for the technical exploitation of geothermal borehole Chochołów PIG-1. Water chemistry has been studied in the area of ionic index markings determining the type of exploitating geothermal water. This paper presents the results of analyzes of selected parameters in the years 2016-2017 and indicates trends in their contents in the given period. The general conclusion is that under operating conditions in accordance with the approved performance, physicochemical parameters are characterized by relative stability. The appropriate exploitation of water from the Chochołów PIG-1 borehole allows for maintaining the proper temperature, which is the underpinning for the functioning of the recreation and balneology complex of the Chochołowskie Termy.

Opis:
At present, hydro-geothermal resources in which waters in bores are the carrier of heat energy have commercial importance in Poland. Geothermal waters should feature the highest possible temperature in the outflow, low mineral content, high capacity and low deposit depth. Even though geothermal energy is included in renewable sources of energy, complete depletion of the deposit is the largest risk in extracting geothermal waters. This is why these waters should also feature deposit renewability. There are currently several geothermal provinces with beneficial geothermal conditions in Poland, with the area of the Podhale Basin in the Inner Carpathians region being regarded as the most promising. The Podhale deposit also meets all of the above listed conditions. The possibility of using hydrothermal energy in Poland is practically available throughout the country, but operational use of hot groundwater must be profitable for investors. From another point of view, the environmental impact of such investments should be minimized. This paper is concerned with the special variety of temperature of geothermal waters extracted in the area of the Podhale Basin, which is the basic aspect in using deposits of this type.

Opis:
The aim of the paper was to determine the possibility of the use of Shewhart control charts to monitor changes in the forms of nitrogen, showing the quality of wastewater discharged from the wastewater treatment plant in Krosno in the years 2010-2015. The performed statistical analysis showed the highest number of cases of elevated nitrate nitrogen and/or ammonium nitrogen when the temperature of treated wastewater was below 8-9°C. This low temperature resulted in adverse effect on the activity of bacteria that were involved in biological removal of nitrogen. It was found that in the winter months, the second stage of nitrifying bacteria responsible for oxidation of nitrite to nitrate, exhibited higher activity than the denitrifying bacteria. Graphical presentation of total nitrogen content using control charts for the mean of the process revealed the exceedance of the upper specification line (USL = 10 mgNtot·dm-3) in the months from December to April. It was observed that the total nitrogen removal process in the months from June to November was stable with a very high 90% reduction in biogenic activity. The obtained results confirm the efficacy of control charts as a tool which can easily be applied in the statistical process control of total nitrogen removal in municipal wastewater treatment plants.

Opis:
The paper presents an analysis of sewage susceptibility to biodegradation on an example of sewage treatment plant in Wodzisław Śląski in the Śląskie province. For this purpose, dependencies between selected indices of domestic sewage pollution were applied. Descriptive statistics of the respective indices rations COD/BOD5 , BOD5 /TN, BOD5 /TPwere presented. Moreover, an analysis was conducted on the composition of raw sewage flowing into the treatment plant, pre-treated sewage and sewage leaving the studied treatment plant. The analysis was carried out on the basis of three basic indices of sewage pollution (BOD5 , COD and total suspended solids) and two biogenic indices (total nitrogen and total phosphorus). Tests on the sewage composition were conducted in the years 2010-2015. Basic descriptive statistics were compiled for the values of the studied indices of sewage pollution and the obtained results were interpreted. On the basis of collected material it may be said that sewage reaching the treatment plant in Wodzisław Śląski revealed a good susceptibility to biodegradation, whereas the BOD5 /TN and BOD5 /TP ratios were below the optimum value.

Opis:
Daily average Alnus pollen counts (1996-2005) from Worcester (UK) and Poznań (Poland) were examined with the aim of assessing the regional importance of Alnus pollen as an aeroallergen. The average number of Alnus pollen grains recorded annually at Poznań was more than 2.5 times that of Worcester. Furthermore, daily average Alnus pollen counts exceeded the thresholds of 100, 500 and 1,000 grains/m3 more times at Poznań than Worcester. Skin prick test results (1996-2005) and allergen-specifi c IgE (asIgE) measurements using the CAP (Pharmacia) system (2002-2005), were supplied by the Allergic Diseases Diagnostic Centre in Poznań. The annual number of positive skin prick tests to Alnus pollen allergens was signifi cantly related (p<0.05) to seasonal variations in the magnitude of the Alnus pollen catch recorded at Poznań (r=0.70). The symptoms of patients with positive skin prick tests to Alnus pollen allergens were: 51% pollinosis, 43% atopic dermatitis, 4% asthma, 1% chronic urticaria and 1% eczema. On a scale of 0-6, 20.5% of patients examined for serum asIgE in relation to Alnus pollen allergens had asIgE measurements in classes 5 and 6. Alnus pollen is generally considered to be mildly allergenic. However, the amount of Alnus pollen released into the atmosphere in places such as Poznań may increase its impact on the population and make it one of the more important aeroallergens present.
