✦ Synopsis

The genotoxic potential of tannery waste water was evaluated by means of the induction of gene conversion and point mutation in Saccharomyces cerevisiae D7 strain. Neither a toxic nor a genotoxic response was obtained after a 2 hr incubation of raw water samples with the strain. A dose-related increase in the induced gene conversion and mitotic reversion was obtained when dilutions of the raw effluent were incubated for 24 hr. Samples of the waste water were also passed through an XAD2 resin column. The column was sequentially eluted with ethyl ether, chloroform and methanol. The ether and methanol fractions showed a positive genotoxic response.
