THE EFFECTS OF INDUSTRIAL EFFLUENT DISCHARGE ON LIPID PEROXIDE LEVELS OF PUNTI FISH (<i>PUNTIUS SOPHORE</i>) TISSUE IN COMPARISON WITH THOSE OF FRESHWATER FISH

ABSTRACT The effect of industrial effluent on the oxidative stress of Puntius sophore (punti fish) tissue was investigated. Oxidative stress was determined by measuring lipid peroxide (LPO) and fatty acid profile as bioindicators. Punti fishes were collected from a river where textile mill effluent is discharged, as well as from fresh water as controls. Homogenized tissues were used for LPO, fatty acid, total cholesterol, phospholipid and protein measurements. LPO levels in both hepatic and extrahepatic tissues increased significantly in the industrial‐effluent‐exposed fish tissue as compared with those of the freshwater fish (control versus industrial‐effluent‐exposed fish: hepatic tissues, 54.0 ± 5.0 and 89.0 ± 9.0 nmol/mg protein; extrahepatic tissues, 52.0 ± 9.0 and 270 ± 16.0 nmol/mg protein). Five biologically important…
