Abstract

Antioxidants are the innate or acquired molecules capable of slowing down or preventing the oxidation of other molecules, thus reduces the oxidative damage (damage due to reactive oxygen species) that caused by free radicals. The Rayapuram fishing harbour of Chennai (Station-1) is highly oil contaminated with oil sleeks on the surface. The relatively moderately oil contaminated area (Station-2) is about 2 km away from the fishing harbour and the least contaminated Vellar estuary Parangipettai (Station-3) was considered as the reference site. The two year (2005-2007) observation was recorded seasonally; the antioxidant activity varied seasonally and organally (digestive gland, gill and mantle) in the marine green mussel Perna viridis. The common antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD) and glutathione reductase (GR) activity were evaluated. The CAT and SOD are responded well with seasons (i.e. monsoon, pre-monsoon, post-monsoon and summer seasons). During monsoon period, both CAT and SOD activity are very low in all the stations, in both pre-monsoon and post-monsoon period their activity were moderate and higher enzyme activity was noted during summer season. On contrary, the GR activity was noted as very low during summer and very high during pre or post monsoon and the activity was moderate during monsoon period. In addition the GR activity responds to temperature also but the other antioxidants COT and SOD yielded no detectable activity. Among the organs liver showed higher COT and SOD activity when compared to gill and mantle but the GR exhibited the increased activity in gill but not in liver.
