农药淡水水生生物水质基准研究进展

水环境质量基准(简称水质基准)是环境保护部门制定水质标准、进行水质管理的基础,其中,水生生物水质基准是保护水生生物物种多样性及充分发挥水生生物群落生态功能的保证,是制定水环境管理目标及措施的重要依据。目前用于推导淡水水生生物水质基准的方法主要有评价因子法、物种敏感度分布曲线法及毒性百分数排序法,综述了3种方法的推导过程、适用范围以及优缺点,并对我国农药淡水水生生物水质基准研究的现状及发展趋势进行了探讨。

Review on aquatic life water quality criteria for pesticides in freshwater

Water quality criteria are essential for the development of standards for water quality and management by government environmental protection agencies.Among them,aquatic life criteria are used to protect the biodiversity and the proper ecosystem function of aquatic life,and ultimately provide a basis for establishing environmental policy and making strategic plan by governments.So far,assessment factor method,species sensitivity distribution curve method and toxicity percentile rank method are popularly used to establish aquatic life criteria.This comprehensive review was on derivation,scope of application,advantages and disadvantages of the three methods.The research status and development tendency of aquatic life water quality criteria for pesticides in fresh water were also discussed.
