Abstract: To study the toxicity of dispersant use upon aquatic organisms, Argopecten irradians was chosen as the research object to investigate the effects of dispersant(10, 50, 100 μg/L)and chemically dispersed 0 diesel(0.025, 0.100, 0.200 μg/L)on the activities of superoxide dismutase(SOD)and catalase(CAT)of the digestive gland at different concentrations by exposure(7 d)and depuration tests(8 d). Results showed that the activities of SOD and CAT were induced in three concentrations of dispersant and two concentrations of chemically dispersed 0 diesel(0.025, 0.100 μg/L)at exposure phase, and the induced time and degree were different under different conditions, implying that SOD and CAT had strong sensitivity and inducibility. The higher the concentration was, the earlier the activity appeared; The inhibition of SOD activity in the high concentration group of chemically dispersed 0 diesel were higher than that in the low concentration group, and the activity inhibition in the high concentration group was earlier than that in the low concentration group, showing the obvious concentration effects. At the end of depuration phase, the SOD activities in the experimental group were significantly higher than that in the control group; However, the CAT activities in the experimental group were significantly lower than that in the control group of dispersant. The SOD and CAT activities of Argopecten irradians had significant differences between the experimental group and the control group of chemically dispersed 0 diesel. And the SOD and CAT activities of Argopecten irradians’s liver could reflect the toxic effects of dispersant and chemically dispersed 0 diesel.

Key words: Argopecten irradians, dispersants, chemically dispersed 0 diesel, antioxidant enzyme
