Abstract

The study of groundwaters was carried out in two different forest ecosystems of Słowiński National

Park: Vaccinio uliginosi-Betuletum pubescentis and Empetro nigri-Pinetum in the period of 2002-2005. Differences were found in the position of the groundwater table and in the concentrations of nitrogen and phosphorus

compounds in the investigated forest associations. In the Vaccinio uliginosi-Betuletum pubescentis association

the groundwater table was found on average at a depth of -73.3 cm, while in Empetro nigri-Pinetum at -90.2

cm. No statistically significant effect of precipitation on the position of the groundwater table was found in

this study. Statistical calculations (U Mann-Whitney test) for groundwaters in the analyzed forest associations

showed statistically significant differences in the dynamics of concentrations of total nitrogen (T-N), organic

nitrogen (Norg.), nitrate nitrogen (N-NO3

), total phosphorus (T-P), organic phosphorus (Porg.) and the level of

groundwaters.

Abstract

A mass balance model lo calculate critical loads of' airborne acidity and cutrophication to forest ecosystems has been computerized. The SONOX soliware developed at the Institute of Environmental Protection replicates the sequence of' events on the path from sulfur and nitrogen emission through their deposition and next overlaying it on critical loads values lo identify the extent and areas of critical loads cxcccdance. To support decision making a converse direction is offered to assess the necessary emission reductions lo meet assumed environmental goals by eliminating or suitably abating the critical loads cxcccdance. This software originally developed and applied to support the Polish contribution lo the negotiations of the Oslo and Gothenburg Protocols or the Convention on Long-Range Transboundary Air Pollution was thereafter used to assess the capacity of achieving the, interim environmental quality targets ofthe NEC Directive in Poland, to support the development of air protection programs lor administrative units exposed to transboundary lluxcs and other decision making purposes.

Abstract

The aim of this study was the application of the geo-accumulation index and geostatistical methods to the assessment of forest soil contamination with heavy metals in the Babia Góra National Park (BGNP). For the study, 59 sample plots were selected to reflect all soil units (soil subtypes) in the studied area and take into account various forms of terrain. The content of organic carbon and total nitrogen, pH, hydrolytic acidity, the base cations and heavy metals content were determined in the soil samples. The geo-accumulation index (Igeo) was calculated, enabling estimation of the degree of soil pollution. The tested soils are characterized by strong contamination with heavy metals, especially with lead. The concentration of heavy metals in the surface horizons of the tested soils exceeds allowable concentration. The content of heavy metals was related to the content of soil organic matter, soil acidity and altitude. Higher altitudes are dominated by coniferous tree stands, which are accompanied by acidic, poorly decomposed organic horizons. Our study has confirmed the impact of pollutants transported from industrial areas on the amount of heavy metals in soils of the BGNP.
