环保视角下的地下水有机污染物指标筛选研究

On Screening Method of Investigation Indexes for Organic Pollutants in Groundwater from the Perspective of Environmental Protection

有机污染物种类繁多,地下水中检出的污染物种类随着检测技术的进步也千差万别,对于地下水污染调查究竟选择哪些有机污染物来进行检测是个急需解决的问题。研究首先基于包容性原则筛选出对人类健康及环境有不利影响的有机污染物,形成初选有机污染物名单。其次根据有机污染物性质与暴露情况,选择有机物毒性(急性毒性与慢性毒性)、持久性、迁移性及有机物在地下水中的检出情况作为筛选方案的影响因子,形成有机污染物筛选名单。研究为日益复杂的地下水有机污染监测提供数据支撑。

With the improvement of detection technology,the types of organic pollutants detected in groundwater vary widely.Thus,it s urgent to determine which organic pollutants need groundwater pollution investigation.First,based on the principle of inclusiveness,this research screened out the organic pollutants that have adverse effects on human health and environment for the preliminary list of organic pollutants.Then,according to the nature and exposure of organic pollutants,the toxicity （acute toxicity and chronic toxicity）,persistence,migration and detection of organic pollutants in groundwater were selected as the impact factors of the screening plan,and the list of organic pollutants was eventually formed.This research provided data support for increasingly complex organic pollution monitoring in groundwater.
