Effect of industrial toxic pollutants on the activity and isoforms of acid DNase in the freshwater snail (Viviparus viviparus L.)

The effect of various toxic compounds (phenol, gasoline, detergents, halogenated benzenes, and copper salts) on the activity and multiple forms of acid DNase was investigated in the liver of the widespread freshwater snail species Viviparus viviparus L. Characteristic variations in the specific activity and isoform pattern of the enzyme depending on pollutant concentration and exposure time were revealed. It was shown that the pattern of DNase isoforms in V. viviparus could be an index of water pollution.
