地球物理方法在地下水有机污染DNAPLs的调查与监测中的应用

地下水有机污染特别是重非水相液体(densenon-aqueousphaseliquids,缩写为DNAPLs)污染是当前国际上地下水污染控制的热点问题,而对DNAPLs的调查与监测也一直是近年来环境地球物理研究的热点。文章简述了DNAPLs的运移、分布规律和DNAPLs与周围土壤及岩石存在的物理性质差异,综述了地球物理方法在DNAPLs的调查与监测应用中的有效性,探讨了地球物理方法直接探测DNAPLs的可行性,并提出了展望。

The Application of Geophysical Technique in Investigating and Monitoring Groundwater Organic Contamination by DNAPLs

Groundwater contamination by organic compounds, especially DNAPLs (Denser Non-aqueous Phase Liquids), is the major concern to groundwater contamination control, and investigating and monitoring DNAPLs are also the focus of recent research on environmental geophysics. This paper discussed briefly the regularity with transport and distribution of DNAPLs and the difference of physical properties between DNAPLs and surrounding soil and rock. The validity of geophysical techniques applied to investigating and monitoring DNAPLs was reviewed. The feasibility of direct detecting DNAPLs with geophysical techniques was explored and the developments were prospected.
