Abstract: The sex ratio,growth,mortality and oocyte development were studied in sluge worm Perinereis aibuhitensis exposed to bisphenol A(at concentration of 0,10,50,100,150,and 200 μg/L)and 17β-estradiol(at concentration of 0,1,5,15,30,and 45 mg/L.The results showed that all females were observed in the sluge worm exposed to the two estrogens.Compared with the sluge worm in the control group,the sluge worms had very significantly better growth in the bisphenol A groups at a concentration of 50 and 100 μg/L(P＜0.01),and significantly better growth in the bisphenol A groups at a concentration of 10 and 150 μg/L(P＜0.05),without significant difference at a concentration of 200 μg/L.However,there were significantly higher mortality in the experimental groups as the increase in concentration of bisphenol.The sluge worms had very significantly better growth in the groups with 17β-estradiol concentrations of 1,5 and 15 mg/L(P＜0.01),while the sluge worm in the group with 30 mg/L showed a significant increase(P＜0.05).The mortality of the sluge worms was found to be increased with increase in concentrations of 17β-estradiol in the experimental groups.There were very significantly higher growth of the oocytes in the Bisphenol A groups(at a concentration of 10-150 μg/L),and in the 17β estradiol groups(at a concentration of 1-30 mg/L)(P＜0.01),but growth of the oocyte was inhibited in the groups with 200 μg/L bisphenol-A and 45 mg/L 17-β estradiol.
