[Impact of chlorination and ozonization on the total mutagenic activity of drinking water]. / Vliianie khlorirovaniia i ozonirovaniia na summarnuiu mutagennuiu aktivnost' pit'evoi vody.

The total mutagenic activity of chemical pollution of the water taken from the Volga water reservoir was investigated after its treatment with chlorine and ozone. The toxicity of the water was absent after its ozone treatment. Mutagens were found to form after water chlorination. Their levels can be reduced by subsequent treatment with ozone in a dose of 0.5 mg/l.
