Temperature can be considered as pro-oxidant factor that favor the generation of ROS on the species with lower antioxidant efficiency may leads to affect the level of tolerance. So the basic antioxidant enzyme activity (LPO, CAT, SOD, GPx and GST) of gastropod Nerita oryzarum was evaluated at six stations which located between the thermal effluent discharges points from Tarapur Atomic Power Station, India. The antioxidant enzyme activity was shown that all enzyme at discharge point (SII station) where the maximum temperature of heated effluent released. The average maximum values of enzyme activity recorded for LPO, CAT, SOD, GPx and GST were 1.88 ± 0.12, 1.52 ± 0.14, 22.57 ± 0.89, 1.98 ± 0.2 and 17.22 ± 0.63 respectively. The results were inferred the level water temperature directly proportional to the oxidative stress by ROS generation in Nerita oryzarum. Similar results were observed at laboratory experiment under the condition i.e., Treatment 1 (30⁰C), Treatment 2 (35⁰C), Treatment 3 (40⁰C) and Control (25⁰C). The present prima facie work clearly indicated the physiological response of N. oryzarum with respect to antioxidant enzyme activity against the heated effluent released, which will be useful as baseline information for future research work.
