摘　　要：[方法]通过毒性试验,得出毒死蜱对长三角地区14种代表性水生生物的毒性数据。分别采用评价因子法、物种敏感度分布法和毒性百分数排序法,推导长三角地区毒死蜱水生生物基准值。[结果]评价因子法、物种敏感度分布法和毒性百分数排序法得出的基准值分别是0.013、0.112、0.021μg/L。比较了3种方法得出的基准值之间的差异,分析了长三角地区毒死蜱水生生物基准与美国、加拿大、澳大利亚和新西兰的基准值不同的原因。[结论]可为我国农药水质标准制订提供科学依据。[Methods] The toxicity data of 14 representative aquatic organisms was obtained through the toxicity tests.The aquatic organism criteria for chlorpyrifos in the Yangtze River Delta Region was derived by assessment factor,species sensitivity distributions and toxicity percentile rank respectively.[Results] The aquatic organism criteria of 0.013,0.112 and 0.021 μg/L was derived by assessment factor,species sensitivity distributions,and toxicity percentile rank.The differences of the criteria were compared.The reasons were analysed that the aquatic organism criteria for chlorpyrifos in the Yangtze River Delta Region was different from America,Canada,Australia and New Zealand.[Conclusions] The obtained results could provide scientific basis for the water quality criteria formulating.
