Effects of benzo(a)pyrene exposure on 7-ethoxyre sorufin O-deethylase activity in Carassius auratus liver

Abstract

Abstract: This paper studied the effects of a typical organic pollutant benzo(a)pyrene(BaP) on the activity of 7-ethoxyre sorufin O-deethylase(EROD)in Carassius auratus liver.The results showed that BaP could induce EROD activity significantly.After injected with 10 and 100 mg穔g^-1 BaP for 96 h,the EROD activity was as 2.3(P<0.05) and 3.1(P<0.01) times as that of the control,and at the 14th day after injected with 1 and 100 mg穔g^-1 BaP,the activity was up to 3.0(P<0.001) and 5.8(P<0.001) times of the control,respectively.The EROD activity in C.auratus liver could reflect the level of BaP exposure,and might be a promising biomarker of the organic pollutant.The minimum effect concentration of BaP on C.auratus was 1 mg穔g^-1(BW).
