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

Published on

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