摘　　要：结合潜在危害指数法和综合评分法筛选大武水源地地下水典型污染物。鉴于潜在危害指数法不考虑污染物的环境浓度,将潜在危害指数作为综合评分法的评价指标之一,同时引进污染物的检出频率、生物降解性、生物累积性、研究区是否有污染源检出、是否为环境激素、是否为美国环境保护署(EPA)优先有机污染物、是否为中国优先污染物、是否为持久性有机污染物等指标,计算不同污染物的综合得分,再通过聚类分析,筛选出典型污染物。研究结果表明,大武水源地地下水典型污染物为三氯甲烷、三氯乙烯、四氯乙烯、四氯化碳和苯。Potential damage index method and comprehensive evaluation method was combined to screen the typical pollutants in groundwater of Dawu water source.Considering the concentrations of pollutants were not counted when calculating the potential damage risk index,the new method which combining potential damage risk index with the comprehensive evaluation method was adapted to screen the typical pollutants in groundwater.Other parameters were introduced in calculating the comprehensive scores of different pollutants.They were the test frequency,biological effect,general/special toxicity for mammals,whether pollution sources were detected and whether the pollution was endocrine disruptor,priority organic pollutant of American Environmental Protection Agency（EPA）,priority organic pollutant of China or persistent organic pollutants.Furthermore,the typical pollutants were screened by clustering analysis.Results showed that the typical pollutants in groundwater of Dawu water source were trichloromethane,trichloro ethylene,tetrachloroethylene,tetrachloromethane and benzene.
