STUDIES ON IMPACT OF CYPERMETHRIN ON ACID AND ALKALINE PHOSPHATASE ACTIVITY IN THE SELECTED ORGANS OF FRESH WATER FISH CIRRHINUS MRIGALA (HAMILTON) AND THE PROTECTIVE EFFECT OF CARDIOSPERMUM HALICACABUM

Abstract

The impact of cypermethrin on acid phosphatase (ACP) and alkaline phosphatase (ALP) activity in gill, liver and kidney on Cirrhinus mrigala, exhibited notable alterations which are being the main site of metabolic activity in fish. The acute toxicity value was found to be 150 $\mu$ g/l and 1/5 as used for LC50 (30 $\mu$ g/l) was selected for sub lethal concentration. The ACP and ALP values in all the organs were decreased due to 120 hours treatment of cypermethrin. These enzymes in various organs were recovered by Cardiospermum halicacabum. Hence the pesticide intoxication has made a disturbance in normal function of cells.
