建议纳入地下水调查指标体系的有机污染物——基于迁移性和致病风险的分析

在地下水有机污染调查中,如何准确地选择测试项目,对于正确认识和评价地下水的污染状况是十分必要的.本文通过参照不同标准或规范中所选择的有机指标,依据它们的迁移性和致病风险,从258种有机物中遴选出了29种地下水污染调查评价规范(2006)中尚未包括的有机物(主要是除草剂和杀虫剂).建议在进行地下水有机污染调查时,依据当地的污染源情况,增加相应的监测指标,特别是要加强对致病风险高和迁移性较高有机物的重视.

Mobility and pathogenic risks of some organic compounds in groundwater and soils

In the investigation of groundwater contamination,the selection of monitoring target organic compounds is very important for the correct assessment of the real situation of groundwater contamination.According to organic compounds involved in the main standards currently used in the world,29 items,which are not included in the Guidelines of Groundwater Contamination Investigation(CGS,2006),are put forward in this paper in the hope that they can be wholly or partly considered in the groundwater contamination investigation in terms of the actual hydrogeological condition and the contaminant sources in the study area.It is suggested that more attention should be paid to the compounds with high mobility and high pathogenic risks.
