中国长江三角洲流域百菌清水生生物基准研究
Aquatic Life Criteria for Chlorothalonil in the Yangtze River Delta Region of China
-
摘要: 通过生态毒理试验,获得百菌清对长江三角洲流域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,推导长江三角洲流域百菌清水生生物基准值。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急性基准值分别是0.066μg·L-1、3.00μg·L-1和0.51μg·L-1,慢性基准值分别是0.0089μg·L-1、0.40μg·L-1和0.136μg·L-1。比较了3种方法得出的基准值之间的差异并分析了原因,在此基础上,提出了我国长江三角洲流域百菌清水生生物基准推荐值,并与国外基准值进行了比较。研究结果可为中国农药水质标准制修订及水生生物风险评估提供科学依据。Abstract: The toxicity data of 14 representative aquatic life was obtained through the ecological toxicity tests. The aquatic life criteria for chlorothalonil in the Yangtze River Delta Region were derived by Assessment Factor, Species Sensitivity Distributions and Toxicity Percentile Rank respectively. The acute aquatic life criteria of chlorothalonil derived by Assessment Factor, Species Sensitivity Distributions and Toxicity Percentile Rank were 0.066 μg·L-1, 3.00 μg·L-1 and 0.51 μg·L-1; the chronic aquatic life criteria were 0.0089 μg·L-1, 0.40 μg·L-1 and 0.136 μg·L-1, respectively. The differences of the criteria which were derived from three methods were compared and the reasons were analyzed. Then, the recommended aquatic life criteria for chlorothalonil in the Yangtze River Delta Region were proposed, and the recommended criteria were compared with criteria of other countries. The results could provide scientific basis for development and revision of the water quality standards and the aquatic risk assessment in China.
