摘要:
Sexually mature male Chlamys farreri were exposed to benzotalpyrene for 10 days at four concentrations at 0, 0.025, 0.5 and 10 mu g/L. Fluctuations in sex steroids during the exposure period were observed, which indicated that sex steroids have a role in gamete development. Exposure to B[a]P altered levels of 17 beta-estradiol, testosterone, and progesterone. Furthermore, B[a]P treatments induced oxidative stress in a dose-dependent manner on spermary of scallop and led to delayed development and damaged spermatid in germinal epithelium of spermary. Overall, B[a]P affected the steroid levels and induced gonadal toxicity at environmentally relevant concentrations. (C) 2015 Elsevier Inc. All rights reserved.
