Seasonal Changes on Glutathione S-Transferase Activities in Perna Viridis on Differently Polluted Areas Along The South East Cost of India

The health of an organism depends on its self protective ability. The regulatory enzyme, biomarkers measurable changes have been used as an effective early warning tool in ecological risk assessment. In order to develop an integrated risk assessment strategy for the South east coast of India. The green mussels Perna viridis were collected from three sites along the southern east coast with different Polyaromatic aromatic hydrocarbons (PAHs) contaminant characteristics. PAHs contents associated responses of detoxification mechanisms evaluated by measuring GST. GST was determined on different tissues (gills, digestive gland, foot) of Perna viridis. The summer showed higher enzyme activity of GST.In the organs wise reaction, the liver showed higher enzyme activity when compared to gill and foot in the enzyme of GST. In the case of three stations from the east coast, The station -1 (Rayapuram harbor) showed a higher enzyme elevation when compared to station-2 (Rayapuram off the coast) and 3 (Parangipettai).
