The effect of three sublethal (2.5%, 5.0% and 7.5% v/v) concentrations of the electroplating factory effluent was studied on then ucleic add profile in the liver of fresh water fish during exposure for 120 days. A significant decline in the liver RNA/DNA ratio of the female fish following exposure to 5.0% and 7.5% concentrations of the effluent was recorded. Also there was a significant decline following exposure to 5.0% and 7.5% concentration of the effluent, when compared with the fish exposed to 2.5% concentration of the effluent. The results also recorded greater decline in the RNA/DNA ratio with increase in the effluent concentration in case of females, but no significant alteration was observed in the liver of male fish following exposure to the three sublethal concentrations of the effluent.
