| 摘 要： | 采用半静态法,在测定毒死蜱对锦鲫急性毒性的基础上,分析了亚致死剂量(96 h-LC50的1/5、1/10、1/20、1/40)作用30 d,毒死蜱对锦鲫(Carassius auratus)的性腺指数(GSI)的影响,并考察了毒死蜱暴露过程和清水恢复过程中锦鲫不同组织对毒死蜱的富集作用,为评价毒死蜱环境生态风险提供依据.结果表明,毒死蜱对锦鲫的96 h-LC50为1.400 mg/L,0.280 mg/L的毒死蜱能够显著抑制雄性锦鲫性腺的发育,毒死蜱在其肌肉和肝脏中的富集量在处理后20 d左右达到累积和释放的动态平衡,组织中的富集量为肝脏>肌肉,清水恢复30 d各组织富集量顺序保持不变. |

| Abstract: | The acute toxicity of chlorpyrifos was measured in Carassius auratus with semi-static method.Carassius auratus was exposed to different sublethal concentrations of chlorpyrifos(1/5,1/10,1/20,1/40 of 96 h-LC50) for 30 d to study the change of gonado-somatic index(GSI).Bioaccumulation effects on different tissues during the process of chlorpyrifos exposure and fresh water recovery were also studied to provide data for environmental risk assessment.The 96 h-LC50 values of chlorpyrifos was 1.400 mg/L.Gonado dev... |
