[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).

[Impact of iodination on the total mutagenic activity of chlorinated tap water].

The impact of iodination on the total mutagenic activity (TMA) of chlorinated tap water was studied. Iodination was made, by using iodine in doses of 0.5 to 4.

[The hygienic evaluation of the mutagenic potential of industrial wastes].

A combination of two approaches to assessing the carcinogenic and mutagenic potentials of industrial waste is proposed. One approach includes determination of the carcinogenic and mutagenic properties of individual chemicals of waste, the other involves biological indication of the cumulative mutagenic activity of waste samples. The mutagenic potential of some waste samples of aircraft industry was determined.
