Abstract

Abstract

The effects of No.0 diesel oil,dimethyl benzene,and Cd²⁺ in sea on the activity of superoxide dismutase(SOD) of Scapharca subcrertata muscle were discussed by inside and outside body contamination.The results indicate that within the dose range inductions of the above three kinds of contaminants to SOD in Scapharca subcrenataare different.The effects of No.0 diesel oil and dimethyl benzene on the activity of SOD of Scapharca subcrertata are basically identical and the dose-effect curves of the two contaminants on the activity of S0D show parabola,while the dose-effect curve of contamination with neither inside body nor outside body display parabola,and significant induction of low concentration of Cd²⁺to SOD exists,and afterwards the curve shows a steep descent,which suggests that Scapharca subcrenata is sensitive to Cd²⁺contamination,and toxicity of Cd²⁺ to Scapharca subcrenata is relatively obvious.The sequence of toxicity of the three kinds of contaminants is as follows:cadmium larger than No.0 diesel oil larger than dimethyl benzene.
- Scapharca subcrertata,
- No.0 diesel oil,
- dimethyl benzene,
- cadmium(Cd²⁺),
- superoxide dismutase(SOD)
