摘  要：
采用静水法生物毒性测试研究重金属(铜和镉)、多环芳烃(菲和萘)及有机农药(溴氰菊酯和氯氰菊酯)3类物质对唐鱼的急性毒性,详细描述中毒症状并进行了安全质量浓度评价。结果表明,铜和镉对唐鱼的96 h的LC50分别为0.054和4.610 mg/L,其中铜属于极高毒物质,镉属于高毒物质,其安全质量浓度分别为0.005和0.461 mg/L;菲和萘对唐鱼96 h的LC50分别为0.913和10.849 mg/L,菲属于极高毒物质,萘属于中毒物质,其安全质量浓度分别为0.091和1.085 mg/L;溴氰菊酯和氯氰菊酯对唐鱼96 h的LC50分别为1.217和6.256μg/L,均属于极高毒物质,安全质量浓度分别为0.122和0.626μg/L。唐鱼对这3类污染物质均有较高的敏感性,适合作为水体污染的监测生物。

摘  要：
The acute toxicity of representative heavy metals(copper and cadmium),polycyclic aromatic hydrocarbons(phenanthrene and naphthalene) and pyrethroid pesticide(deltamethrin and cypermethrin) to White Cloud Mountain minnow Tanichthys albonubes were studied by using the static-test method in the laboratory.The results showed that,the 96 h-LC50 for copper and cadmium to the minnow were 0.054 and 4.610 mg/L,respectively;copper was a drastic toxicant and cadmium was a high toxicant to the minnow.And the safe concentrations of these metals were 0.005 and 0.461 mg/L,respectively.The 96 h-LC50 for phenanthrene and naphthalene to the minnow were 0.913 and 10.849 mg/L,respectively.Phenanthrene was a drastic toxicant and naphthalene was a medium toxicant to the minnow.And the safe concentrations of these PAHs are 0.091 and 1.085 mg/L,respectively.The 96 h-LC50 for deltamethrin and cypermethrin were 1.217 and 6.256 μg/L,respectively.Deltamethrin and cypermethrin were both drastic toxicants to the minnow.And the safe concentration of them are 0.122 and 0.626 μg/L,respectively.The minnow was very sensitive to these three kinds of pollutants and it could be used as a biological agent for evaluating and monitoring relative water pollution.
