Abstract: | The marine bivalve, Perna viridis was exposed to sublethal concentration (one third of 24 h LC50) of either cadmium or copper for 1, 3 and 7 days and alterations in lipid peroxidation in the gill and muscle were investigated. Significant increase of the level of malondialdehyde, which is indicative of the peroxidative process, and a decrease of activity levels of glutathione peroxidase and glutathione transferase were observed in both the tissues of copper exposed mussels. the exposure of mussels to cadmium did not elicit any of the above changes. |
