IMPACT OF ELECTROPLATING EFFLUENT ON THE NUCLEIC ACIDS PROFILE IN THE LIVER OF FRESHWATER FISH, HETEROPNEUSTUS FOSSILIS (B1)

Abstract

The effect of three sublethal (2.50/., 5.0% and 7.5% v/v) concentrations of the electroplating factory effluentwas studied on the nucleicadd profile in the liveroHreshwaterfish during exposure for 120 days. Asignificant decline in the liver RNAIDNA ratio of the female fish following exposure to 5.0% and 7.5% concentrations of the effluentwas recorded. Also there was a significant decline following exposure to 5.0% and 7.5% concentration of the effluent, whencomparedwith the fish exposed to 2.5% concentration ofthe 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.
