IMPACT OF FIREWORK INDUSTRY EFFLUENT ON THE FISH CYPRINUS CAR AND ITSBIOREMEDIATIONPAULINE RAJAN,K.KAMALAVENI AND URSULA SAMPSONAbstract Effluents are found to possess prooxidants. Organisms, when come in its contact are prone to oxidative stress (OS) due to Reactive Oxygen Species (ROS) generation. Superoxide dismutase (SOD)is an antioxidant enzyme which combats ROS. Measurement of malondialdehyde (MDA) quantifies the lipid peroxidation (LPO) caused by ROS. Bioremediation using water hyacinth is an environmently friendly option for the depollution of effluent .The activity levels of SOD,LPO and protein in various tissues of the fish exposed to 20°/0,40% and 60% concentrations of raw and plant treated effluent were assessed for 24, 48 and 72 hrs. The significant increase of SOD and LPO and decrease of protein in raw effluent and the concomitant decrease of SOD and LPO and increase and total protein in plant treated effluent are discussed in relation to bioremediation.
