Abstract
These studies present a approach to analysis of micronuclei (MN) and other nuclear anomalies (ONA) in erythrocytes of toad (Bufo bufo andrewsi) tadpoles,induced by exposure to polluted water of Daguan River.Tadpoles were exposed to polluted water of three different concentration (33.3% 50.0% and 100.0%) for 7 days.In the control,total frequency of nuclear anomalies (including micronuclei) was 4.1‰;Total frequencies of ONA for the above mentioned experiment groups were 8.1‰,10.8‰ and 15.8‰ respectively.The frequencies of MN and ONA in erythrocytes of tadpole,in various groups,showed distinct dose dependent increases.Our results shown that MN and ONA in erythrocytes of toad tadpole is useful index for detecting genotoxic compounds in the aquatic environment.
