摘要
With carps as the object of study, the effects of benzo[a]pyrene concentration on SOD and CAT in carp kidneys were studied. There were three treatment groups and one control group. The exposure method was the static method. The superoxide dismutase （SOD） and catalase （CAT） activity was determined 30 d later. The results showed that after exposing to different concentrations of benzo[a]pyrene （0, 0.1, 0.5 and 1.0 μg /L） for 30 d, the SOD activity was higher in the low concentration group （0.1 μg/L） than in the control group; the 0.5 μg/L benzo[a]pyrene group had no significant difference from the control group; and under the concentration of 1.0 μg/L, the SOD activity decreased remarkably. The CAT activity was higher in the 0.1 μg/L group than in the control group, and decreased significantly in the 1.0 μg/L benzo[a]pyrene group compared with the control group. The results showed that benzo[a]pyrene had certain effects on the antioxidant enzymes in carp kidneys. This study provides a theoretical basis for water environmental pollution.
