Abstract: Changes in activities of antioxidant enzyme superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST) ,peroxidase (POD) and lipid oxidation degree (content of malonyldialdehyde, MDA) in livers, gills and muscles of Sparus macrocephalus exposed to water soluble fractions of No.0 diesel fuel (WSF) were studied, to quantitatively assess toxicity of No. 0 diesel fuel to the fish using the integrated biomarker responses(RIB)index method. Results show that once exposed to 0.60, 0.30 and 0.015 mg·L-1 of WSF, the fish were subjected to a regular pattern of change, i.e. induction-inhibition, in activities of SOD, GST and CAT in liver, gill and muscle, and in activity of POD as well. MDA content showed a reverse trend, that is, declining first and then rising. The effects varied somewhat from organ to organ, and the effect of inducing enzymatic activities was observed earlier in liver than in the other organs. In terms of oxidation stress tolerance obtained through RIB analysis, the organs followed an order of liver > gill > muscle. On the whole, RIB varied in a trend, rising first and then falling and RIB in liver was positively related to WSF concentration of No. 0 diesel fuel.
Key words: Sparus macrocephalus, No.0 diesel fuel, antioxidant enzyme, integrated biomarker responses
