摘　　要：通过开展毒性试验和查阅国内外相关文献,获取马拉硫磷对长江三角洲流域22个代表性物种毒性数据,采用物种敏感度分布法和毒性百分数排序法推导长江三角洲流域马拉硫磷水生生物基准值。结果显示,采用物种敏感度分布法得出的急性基准值和慢性基准值分别为0.865 5和0.036 2μg·L^(-1),采用毒性百分数排序法得出的急性基准值和慢性基准值分别为0.400 0和0.033 4μg·L^(-1)。为充分保护水生生物,建议以毒性百分数排序法推导出的基准值作为长江三角洲流域马拉硫磷水生生物基准推荐值。研究结果可为我国地表水环境质量标准修订及水生生态风险评估提供科学依据。The toxicity data of 22 representative aquatic organisms were collected from the laboratory toxicity tests,authoritative toxicity databases and published in literature following principles of accuracy,relevance and reliability. The aquatic life criteria（ ALC） for malathion in the Yangtze River Delta Region were derived by Species Sensitivity Distributions（ SSDs） and Toxicity Percentile Rank（ TPR） respectively. The results show that the acute and chronic ALCs of malathion derived by SSD were 0. 865 5 and 0. 036 2 μg·L^（-1）,respectively; the acute and chronic ALCs of malathion derived by TPR were 0. 400 0 and 0. 033 4 μg·L^（-1）,respectively. The final criteria derived by TPR were recommended as ALCs for malathion to protect aquatic organisms in the Yangtze River Delta Region. In addition,the recommended ALCs for malathion were compared with criteria abroad and existing Chinese water quality standards（ WQS）. The present research could provide scientific reference for WQS revision and aquatic risk assessment in China.
