摘要

采用综合评分法对下辽河平原区域地下水典型污染物进行筛选,选取的评价指标包括污染物的检出频率、生物效应、对哺乳动物的一般毒性、特殊毒性、研究区是否有污染源检出、是否为环境激素、是否为美国EPA优先有机污染物、是否为中国优先污染物、是否具有环境持久性等9大类14个单项指标,引入指标权重计算得出各污染物的综合评分结果,通过聚类分析,筛选出典型污染物.研究表明:下辽河平原区域地下水中筛选出了典型污染物包括Hg、Pb、Cd、As、甲苯、α-六六六、β-六六六、六氯苯和苯并(a)芘等.

Abstract

Comprehensive evaluation was used for screening of typical pollutants in groundwater in the Liao River basin.Nine categories of parameters of pollutions combined with index weight were introduced in calculating different pollutant-weighted scores.Parameters included test frequency,biological effect,general/ special toxicity for mammals,detectability of pollution sources and pollutant endocrine disruptability,and whether they were priority organic pollutant of American Environmental Protection Agency,priority organic pollutant of China or whether they were persistent organic pollutants.Typical pollutants were screened by cluster analysis. Typical pollutants in groundwater of Liao River basin included Hg,Pb,Cd,As, methylbenzene,α-hexachlorocyclohexane,β-hexachlorocyclohexane,hexachlorobenzene,benzo(a)pyrene.
