摘要
C-6-C-12 and C-12-C-35 hydrocarbon fractions and aromatic hydrocarbons were sep. extd. from soil samples with MeOH, hexane and CH2Cl2, resp. Then exts. were analyzed by gas chromatog. coupled to a mass spectrometer, and the obtained results were compared with the permissible concn. of pollutants in the soil. In addn., the abundance of heterotrophic bacteria after incubation (room temp., time 72 h) and micro flora activity (dehydrogenase, lipase, cellulose) were estd. for soil samples. For most of them, the contents of both hydrocarbon fractions as well as alkylbenzenes and naphthalene were above the permissible values while abundance of heterotrophic bacteria and micro flora activity was slightly below for soil values without contaminations of petroleum products.
