长江三角洲流域保护水生生物优先控制农药品种筛选

Screening of Pesticides for Priority Control for the Sake of Protecting Aquatic Organisms in the Yangtze River Delta Basin

以长江三角洲流域为研究区域,首先明确了以保护水生生物为目标的优先控制农药品种的筛选原则,并以模型预测为基础,根据农药对水生生物的风险性,筛选形成了长江三角洲流域保护水生生物优先控制农药品种名录。名录共包含15种农药有效成分,一方面可为我国地表水农药生态基准的制定提供优先次序,另一方面对于长江三角洲流域地表水体农药污染控制具有重要的指导意义。

For protection of aquatic organisms in the Yangtze River Delta Basin, it is essential to define principles for screening out pesticides for priority control. Based on the prediction with models, pesticides commonly used in the region were screened in light of their predicated risks to aquatic organisms, and a pesticide priority control list involving 15 pesti？cide active ingredients was worked out. The list could provide a priority list for formulating a national surface water ecologi？cal criteria for pesticides, and also serve as guidance for control of pesticide pollution in surface water bodies in the Yan？gtze River Delta Basin.
