[Analysis of the mutagenic activity of aqueous and buffer extracts from oil-polluted soil samples].
The Ames test on Salmonella typhimurium TA 100 and TA 98 strains were used to study the mutagenic activity of aqueous (pH 7.4) and buffer (pH 4.5) extracts from soil samples containing different oil levels (from 16 to 3526 mg per kg soil), which had been taken from different areas of a town, and buffer extracts from model soil samples added by crude West-Siberian oil (160-15625 mg/kg). The extracts from all soil samples showed no mutagenic activity. The buffer soil sample extract containing oil in the amount of 12290 mg/kg and oil and coal combustion products had a mutagenic effect with metabolic activation on the TA 98 strain. It is suggested that the mutagenic effect of this sample is associated with oil and coal combustion products.
