C-6-C-12 and C-12-C-35 hydrocarbon fractions and arom. hydrocarbons were extd. from 8 soil samples with MeOH, hexane and CH2Cl2, resp. Then exts. were analyzed by gas chromatog. coupled to a mass spectrometer. The obtained values were compared with the max. values set in the national legislation. In addn., the relative changes in seeds germination capacities of selected plants (sorghum and cress) and relative changes in the length of stems and roots of these plants, grown on the tested soil samples were compared to these plants cultivated on soils without contamination. Cultivations on soils with a high content of hydrocarbons revealed limitations of the growth of the sorghum roots length to 19% and of the cress roots length as well as its stems up to 25%. Changes in a seed germination capacities of selected plants in soil depending on hydrocarbon pollutions were not obsd.
