Effect of a vegetable oil factory effluent on in vitro lipid and protein synthesis by the liver of the freshwater teleost Heteropneustes fossilis (Bloch).

Following exposure to three sublethal concentrations (5, 10, and 15% v/v) of vegetable oil factory effluent for 30 days (March 1 through March 30, 1984), during the preparatory phase of the annual reproductive cycle of Heteropneustes fossilis, the in vitro incorporation, of [14C]glucose/[14C]/acetate into the lipids and of [14C]leucine into the proteins by the liver declined when compared with the control. In the three concentrations of the effluent used, the decline in the incorporation of radiolabelled substances increased with increase in the concentration.
