OB - 74B: Recultivation soils of Yavoriv national park and military range with the help of nonconventional local fertilizers and plants - accumulators.

The works for determination of pollution of soils and some kinds of vegetation (heath, cowberry, bilberry, hornbeam and birches) with heavy metals and radionuclids of uranium and thorium family and 40K in area of Roztochchya reserve and the military range located in Javorivskyy area of Lviv region are continued. It is specially was emphasized on determination of dependence between amount of heavy metals and radioniclids in sample and sampling depth, type and soil properties, relief etc. The total number of selected samples is near 80. According to a computer-based analysis, the effect of above-mentioned parameters on the results of investigations, correlation between different chemical elements in samples, the background pollution in soils and vegetations (heath, cowberry, bilberry, hornbeam, birch etc.), factors of accumulation of chemical elements in soils of different types and vegetation (excess of individual parameters over background ones), correlations of microelements in different parts of plants (leaves, trunks, roots) have been determined. From the intensity of accumulation of chemical elements the adsorption-accumulation series have been defined. With the aim to determine the effect of State Mining Enterprise "Sirka" on environment pollution the works have been carried out in the region of its activity. The amount of heavy metals and radionuclids in samples of different rocks, picked up in open-cast mine and boreholes (limestones, sandstones, clays, sulfuric ores, etc), have been determined. Total number of selected samples is near 30 ones.
