PLANKTONIC ALGAE – BIOINDYCATORS OF THE EUTROPHICATION LEVEL OF TWO DAM RESERVOIRS: WAPIENICA AND KOZŁOWA GÓRA
Ewa Jachniak, Janusz Leszek Kozak
Summary
In this publication the qualitative structure of planktonic algae was presented. These planktonic algae spread out in two separate dam reservoirs: Wapienica and Kozłowa Góra. There was also presented the biomass largeness of phytoplankton. The estimate of eutrophication was performed by taking into consideration of the indicator taxons; there was used the classification proposing by Heinonen (1980), too. This classification considers the biomass largeness of phytoplankton. The typical taxons for oligotrophic water were observed in the samples of water taking from the reservoir of Wapienica, however the typical taxons for eutrophic water occured in the samples of water taking from the reservoir of Kozłowa Góra. The examinations concerning the average biomass of phytoplankton allowed classification the reservoir of Wapienica to oligo-/mesotrophic reservoirs, but the reservoir of Kozłowa Góra to hipertrophic reservoirs.

METHODOLOGICAL ASPECTS OF PRECIPITATION SAMPLING FOR HEAVY METALS CONTENT INVESTIGATION
Anna Degórska, Urszula Białoskórska, Dorota Typiak-Nowak
Summary
The aim of the described experiment was testing of two methods used for collecting precipitation samples at the forest (throughfall and stemflow) for heavy metals analyses. Comparison of data obtained using two methods – samples collectors made of glass and acidification of the collected samples and polyethylene collectors without acidification – has shown that the results are much smaller when standard samples were analyzed (standard samples – collected for main ions analyses). It is particularly important in case of cadmium, lead and zinc. This experiment has shown importance of proper measurement method taking into account the aim of the research, starting with samples collecting. Precipitation samples for heavy metals analyses should be collected by the collectors made of glass and after that should be acidified in order to avoid loss of the components that are subject of the investigations.

PHYSICOCHEMICAL PROPERTIESOF BEAVER WETLANDS WATER
IN THE KŁUDA VALLEY
Grażyna Szpikowska, Józef Szpikowski
Summary
Beavers settle entails various changes in the functioning of geoecosystems: hydrological (associated with the conditions of flow and drainage of water from the catchment and the conditions of retention), geomorphological, affecting the level of biodiversity and affecting the water quality. Research undertaken in the Kłuda catchment, a tributary of the upper Parsęta (Drawskie Lake), focused on knowledge of water chemistry within the beaver wetlands. The quality of these of waters compared with the chemistry of groundwater in the adjacent slope system and river water. It was changes in the oxygenation of groundwater and waters stagnant on the surface of beaver wetlands. Reducing conditions in the waters of beaver wetlands reduce the concentration of nitrate ions. The groundwater in the zones of beaver wetlands reduction of the concentration of sulphate ions and increase the concentration of ammonium ions and phosphate are observed. Beaver wetlands in the Kłuda catchment partially limit loads eutrophying components

THE RELATIONSHIP BETWEEN THE CONCENTRATIONS OF HEAVY METALS AND PM10 AND METEOROLOGICAL PARAMETERS
IN THE PUSZCZA BORECKA REGION IN THE YEARS 2005-2011
Zdzisław Prządka, Anna Degórska, Krzysztof Skotak
Summary
The assessment of the impact chosen meteorological parameters on the concentrations of particulate matter (PM10) and it contains heavy metals at the level of regional background in North-Eastern Poland was the aim of research. Analysis of data based on the results of the measurements carried out on the Puszcza Borecka Station of Institute of Environmental Protection – National Research Institute in the years 2005–2011. The calculated coefficients of determination are presented in terms of seasonal and annual basis. Presented analyzes showed that most factors contributing to the decrease in the PM10 concentration in the colder half of the year are growth of height and duration of precipitation and increase in wind speed. In the warm season, the intensity of the precipitation, the air temperature and the intensity of the solar radiation play most important rule. Effects of meteorological conditions on concentration of heavy metals is varied. Referring to the highest concentrations of metals (zinc, lead and arsenic), it can be concluded that in the colder half of the year the factors contributing most to their decrease concentrations are increase air temperature, increase irradiance and decrease relative humidity of the air. In the warm half of the year, the increase in intensity of solar radiation and precipitation, air temperature and decrease relative humidity air contributes the most to the decline concentration of most heavy metals contained in PM10 particulate matter. Effect of wind speed and air pressure on the concentration of heavy metals in PM10 proved to be the smallest.

THE CONCEPT OF WATER ENVIRONMENT PROTECTION
IN THE KARKONOSZE NATIONAL PARK
Henryk Marszałek, Michał Rysiukiewicz
Summary
Water belonges to the most important elements of the natural environment of Karkonosze Mts., forming a number of natural processes and representing resource useful for supplying the local population with drinking water. Therefore it should be protected and monitored continuously. The paper presents the concept of water environment protection in the Karkonosze National Park (KPN), including a proposal for monitoring the quantity and quality of surface and groundwater in both, the whole area of the Karkonosze Mts. and selected three representative catchments: Kamieńczyk, Wrzosówka and Łomnica rivers. It has been proposed the scheme of monitoring network arrangement with the range and frequency of water as well.

INFLUENCE OF CEMENT-LIME INDUSTRY ON THE PHYSICO-CHEMICAL AND CHEMICAL PROPERTIES OF SNOW COVER IN A „BIAŁE ZAGŁĘBIE” REGION
IN FEBRUARY 2012
Rafał Kozłowski, Krzysztof Jarzyna, Marek Jóźwiak, Mirosław Szwed
Summary
The aim of the study was to determine the effect of cement and lime industry, the quality of the snow cover within Białe Zagłębie in the Świętokrzyskie Mountains. Analyzed the meteorological and orographic conditions which determine the keep of snow cover during the winter 2012 and identified emission sources and determining the chemical properties water obtained from melted snow collected in the field. Laboratory tests were carried out using a gas chromatograph ion DIONEX ICS-300 multiparameter meter CX-701 and ORIGIN 8.6 and STATISTICA and 10.0. software. The obtained results allow to a large extent determine the role of snow cover as an indicator of air pollution in an area with significant industrial anthropogenic, indicating the serial nature of additional factors that determine its size.
