摘要

摘要:以白洋淀淀中村地下水水樣采集與分析為依據(jù)，采用US EPA推薦的健康風(fēng)險評價方法綜合評價淀中村由于非規(guī)范垃圾堆放導(dǎo)致的地下水污染對周邊居民造成的健康風(fēng)險。結(jié)果表明，淀中村地下水污染的目標(biāo)污染物為NO3- -N、NH4+ -N、Cr6+和Hg；成年人和兒童兩類人群經(jīng)口暴露途徑的健康風(fēng)險均遠(yuǎn)大于皮膚暴露；成年人經(jīng)口暴露的風(fēng)險大于兒童，而其皮膚暴露的風(fēng)險小于兒童；4種目標(biāo)污染物中，Hg的風(fēng)險貢獻最大，其風(fēng)險貢獻率達(dá)98%；地下水污染對人體的非致癌風(fēng)險大于1，該地區(qū)地下水對當(dāng)?shù)鼐用袢梭w健康造成的風(fēng)險應(yīng)該引起重視。

Abstract:On the basis of the analysis of the groundwater samples collected from a village located in Baiyangdian Lake, the health risk assessment model recommended by US EPA was applied to evaluate synthetically the local residents’ health risk that was caused by groundwater contamination of non-formal solid waste dumping sites. The results showed that the target contaminants of the village groundwater were NO3- -N, NH4+ -N, Cr6+ and Hg. For exposure public of adults and kids, the health risk via dietary intake exposure path was largely higher than the health risk via dermal intake exposure path; exposure risk of adults via dietary intake was higher than kids via dietary intake and the exposure risk of adults via dermal intake was lower than kids via dermal intake. Among four kinds of target contaminants, Hg risk contribution rate was 98% and ranked the first place. Non-cancerous risk level of groundwater contamination was more than 1, so more attention should be paid to the residents’ health risk caused by non-formal solid waste dumping sites groundwater contamination.
