ENZYMATIC CHANGES DURING LETHAL AND SUBLETHAL EXPOSURES OF GLYPHOSATE (41% SL) ON FRESHWATER FISH CIRRHINUS MRIGALA

The lethal and sublethal effect of the Glyphosate (41% SL) on certain enzymes in tissue such as AAT (Aspartate Amino Transferase), ALAT (Alanine Amino Transferase), LDH (Lactate Dehydrogenase) and ACP (Acid Phosphatase) of the freshwater fish, Cirrhinus mrigala during and after the cessation of the exposure were observed. Ten fish were exposed chronically to lethal and sublethal concentrations for a period of 4 days were sacrificed and tissues such as brain, gill, liver, kidney and muscle were analysed for biochemical parameters and remaining five fish were maintained in clean well water for a period of seven days without test substance being spilled in the water and its tissues were collected after reversal period for biochemical analysis. Marked changes were observed in the biochemical parameters of the fish exposed and after the cessation of the exposur
