淮安某县农村饮用水源中优控污染物的筛选研究

在对淮安某县农村饮用水源中的污染物检测分析的基础上,采用潜在危害指数法与综合评分法对水源中检出的包括重金属在内的59种污染物进行优先排序.研究结果显示,潜在危害指数法与综合评分法各有利弊,可根据实际情况选择合适的筛选方法.综合两种方法的筛选结果,淮安某县农村饮用水源中优控污染物为Cd、Hg、Pb、Ni、Cr、As、Cu、苯并(a)芘、五氯联苯、邻苯二甲酸二丁酯、邻苯二甲酸二(2-乙基己基)酯、四氯化碳,研究结果为该地区农村饮用水源的管理提供了指导方向.

Screening of priority control pollutants from the rural drinking water sources in Huai'an City

Based on the monitoring data of the drinking water sources in Huai￠an City of Jiangsu Province, potential risk index method and composite scoring method were applied to screen the priority control pollutants out of 59 pollutants detected in the water. Comparison of the two methods showed that each method had its advantages and disadvantages, and one should choose appropriate screening method based on practical conditions. Twelve chemicals including Cd, Hg, Pb, Ni, Cr, As, Cu, benzo (a) pyrene, PCB5, dibutyl phthalate, bis (2-ethylhexyl) phthalate, and tetrachloromethane were determined as priority control pollutants by the score values calculated by the two methods. Results from this study are helpful to support drinking water sources management.
