It is well known that the marine organisms are used as biological indicators for environmental pollution studies. Among these studies, the research on oxidative stress has been increasing in recent years. In this study, mussels (Mytilus galloprovincialis) and fish (Solea solea) samples were collected seasonally from inciralti, Izmir, Turkey. This station was in an area where fishing is carried out for human consumption. The relationship between Po-210 and oxidative stress markers (lipid peroxidation (LPO), H2O2 and proline) was investigated in the mussel tissue (digestive gland, gills) and fish tissue (liver, gills) samples. The present study indicated that H2O2 accumulated with increasing Po-210 concentration in mussel samples. Statistically significant correlation were found between H2O2 and Po-210 and LPO and proline in mussel samples. This correlation between LPO and proline can be attributed to common environmental parameters (other than Po-210) affecting expression of both LPO and proline levels. There was not a significant correlation between Po-210 and LPO levels. Similarly, a significant correlation was not found between Po-210 and proline.
