Our investigation was localized in the area of fuel base A of the former Soviet firing ground Borne Sulinowo, where petrol contamination of soils had been observed. The suspenssion of yeast strain Yarrowia lipolytica A–101 was introduced into twelve one-metre deep bore-holes. The process of bioremediation was controlled using electromagnetic and resistivity methods, and microbial enumeration was done on Hy–Check slides. The measurements were carried out along the same profile in spring 2003, autumn 2003 and spring 2004. The significant increase of electrical conductivity of soils was observed in the vicinity of bore-holes with introduced yeast. The study showed the ability of Yarrowia lipolytica yeast to remedy petrol contaminated soils and the efficiency of applied geoelectrical methods to this process monitoring.

This paper presents the results of determination of artificial 137Cs and natural 40K activity concentrations in plants (bilberry (Vaccinium myrtillus) and moss (Polytrichum commune)) and in soil samples from two main Tatra Valleys; Kościeliska and Rybi Potok Valley. The data were obtained during two years (2001- 02). These plants are known a as good bio-monitors for radioceasium [1,2 ]. It is known that 137Cs and 40K isotopes play important roles in the environment, due to their good assimilation by plants. The transfer of these elements from soil to plant depends of many factors: type of soil, organic matter contents, pH, type of plants. In this paper some results concerning the transfer of 137 Cs and 40K isotopes from various types of Tatra soil to moss or bilberry are shown.

Investigations have been carried out on the soil material taken from 46 profiles representing lithogenic soils from non-forest areas of the Tatra National Park. When selecting soil material an altitude above sea level (over 1250 m a.s.l.), a rock parent type (non-calcareous and calcareous) were taken into account, in case of non calcerous soils, the weakly developed soils - rankers were selected. On the basis of the investigetions the following conclusions have been drawn: sorption properties of ectohumus horizons in most of investigated lithogenic soils (rankers and rendzinas) are differ- enciated and formed under the influence of parent rocks. Ectohumus of Oh horizons of rankers sorbed exchangeable cations in following order H+>Ca2+≥Mg2+>K+>Na+. In composition of cations in Oh horizons of rendzinas dominated cations of calcium and the order was as follows: Ca2+>Mg2+>H+>K+≥Na+. In ectohumus of Oh horizons of rendzinas occurring under bilberry heath and pine dwarf and rankers the composition of exchangeable ions as well as a degree of base saturation were close. In investigated soils sorption properties of mineral or organic-mineral horizons AC or ABC, occurring in direct contact with the parent rock, were formed under the influence of lithogenic factor.
