地下水有机污染健康风险评价研究综述

Research Review on Health Risk Assessment of Organic Pollution in Groundwater

对健康风险评价的概念、内容及研究状况进行了概述,介绍了地下水有机污染健康风险评价的两种主要方法——美国国家科学院(NAS)和美国国家环保局(USEPA)提出的健康风险评价方法,综述了国内外地下水有机污染健康风险评价的研究现状.在此基础上,分析了当前我国地下水有机污染健康风险评价在评价过程、内容、计算及与实际相结合等方面存在的问题和不足,提出了今后研究的发展方向,即制订适合我国实际情况的评价方法和技术指南性文件,丰富风险评价的影响因素,开展溶质运移研究及风险评价的不确定性研究.

In this paper, the research status, content and concept of health risk assessment were reviewed, the methods of health risk assessment from United States National Academy of Science and United States Environmental Protection Agency were introduced, and the status of health risk assessment on organic pollution in groundwater at home and abroad was summarized. Further, these were discussed, such as the existing problems and shortcoming in evaluation process, evaluation content, calculation and combination of evaluation with the actual situation, and then the future trends of research for health risk assessment of organic pollution in groundwater were provided, including formulating the evaluation method and the technical guidance files to suit Chinese actual conditions, enriching the influence factors of risk assessment, and carrying out research on solute transport and uncertainty of assessment.
