多环芳烃(Polycyclicaromatichydrocarbons，PAHs)是海洋中常见的污染物，极易在环境中累积并可通过食物链传递，对人类健康和生态环境具有很大危害。已有研究表明PAHs具有致畸、致癌、致突变、免疫抑制等作用。本研究利用环境水平（0.5、5、50nmol/L）三环的菲(phenanthrene，Phe)和四环的芘(pyrene，Pyr)以及（0.5、5、25nmol/L）五环的苯并(a)芘[benzo(a)pyrene，BaP]分别暴露褐菖鮋胚胎，研究PAHs对鱼类胚胎发育的毒性。 PAHs暴露囊胚期胚胎7天，其中0.5和25nmol/LBaP组死亡率显著高于对照组；...Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants being found in aquatic areas. Exposure to PAHs is linked to teratogenesis, carcinogenesis, mutagenesis, immunosuppression and other numerous health problems. In the present study, Sebastiscus marmoratus embryos exposure to benzo(a)pyrene (BaP, 5-ring), pyrene (Pyr, 4-ring) and phenanthrene (Phe, 3-ring) at environme...学位：理学博士院系专业：生命科学学院生物学系_动物学学号：2172009015353
