EPA Aquatic Life Benchmarks

EPA worked initially with the U.S. Geological Survey to identify aquatic ecotoxicity benchmark values from risk assessments developed by EPA for individual pesticides during previous re-registration programs. The Overview of the Ecological Risk Assessment Process and ecological risk assessments developed for individual pesticides provide an understanding of the ecotoxicity data used to develop benchmarks. Comparing a measured concentration of a pesticide in water with an Aquatic Life Benchmark can be helpful in interpreting monitoring data and in identifying and prioritizing sites and pesticides that may require further investigation.美国环境保护署（EPA）最初与美国地质调查局（U.S. Geological Survey）合作，从EPA此前在农药重新注册项目中针对单个农药制定的风险评估报告中，提取水生生态毒性基准值。《生态风险评估流程概述》及针对单个农药制定的生态风险评估报告，可帮助研究者理解用于生成上述基准值的生态毒性数据。将水体中实测的农药浓度与水生生物基准值（Aquatic Life Benchmark）进行比对，有助于解读监测数据，同时可辅助识别需进一步开展调查的点位与相关农药，并完成优先级排序。

背景概述

EPA Aquatic Life Benchmarks数据集提供了美国注册农药的水生生物基准值，这些值基于EPA在生态风险评估中审查的毒性研究，用于评估农药对淡水生物的风险。该数据集源自EPA与美国地质调查局的合作，旨在帮助解释环境监测数据，并协助州、部落和地方政府识别和优先处理需进一步调查的农药污染地点。基准值会定期更新，以反映最新的科学评估成果。
