摘要
本研究旨在评估生活垃圾填埋场重金属对周边地下水环境的影响,并利用健康风险评估模型,对其可能带来的健康风险进行评估.结果表明:不同污染物总非致癌危害商排序为Cr6+＞As＞Pb＞Hg＞Zn＞Cu＞Mn;儿童的总非致癌危害商高于成人;所有污染物的总非致癌危害商均在可接受范围内.
Abstract
The purpose of this study was to assess the impact of heavy metals on the surrounding groundwater environment,and to assess the potential health risks by using a health risk assessment model.The results showed that the total non-carcinogenic hazard quotient(NHI)of different pollutants ranked as CR6+>as≫PB≫HG≫ZN>CU>MN;children had higher NHI than adults;The total non-carcinogenic hazard quotient of all pollutants was within the acceptable range.
