摘要:
选择常州市2条穿过城区、郊区和农村的道路为典型研究对象,在道路两侧150m范围内采集住宅灰尘样品51个,分别测定Cu、Zn、Pb、Cd、Ni和Cr 等6种重金属含量,并进行了污染源分析和健康风险评价。结果表明,城区、郊区和农村住宅灰尘重金属含量均不同程度的超过了江苏省土壤背景值,其中Pb、Cd、Cu和Zn污染普遍比较严重,Pb和Cd可能主要来自交通源,Cu和Zn可能受交通源和工业源的复合污染; Cr和Ni污染较轻,可能主要来自于自然源。健康风险评价结果表明,非致癌物Cu和Zn对人体没有明显危害,而Pb存在一定危害; Cd和Ni对儿童和成人的致癌风险指数均在可接受范围之内,而Cr则有较大的致癌风险。
Abstract:
Two roads through the city, suburban and rural roads in Changzhou were selected and 51 roadside household dust samples were collected within the range of 150m alongside the road. The Cu, Zn, Pb, Cd, Ni and Cr contents were determined, and the analysis on pollution sources were conducted and the health risks were evaluated. The results show that heavy metal contents of urban, suburban and rural household dust are higher than the soil background values of Jiangsu Province, where Pb, Cd, Cu and Zn pollution were generally more serious. Pb and Cd may mainly result from traffic sources, Cu and Zn may be polluted by industrial sources and traffic sources. There are less pollution from Cr and Ni, which may come from natural sources. Health risk assessment results show that Cu and Zn(non-carcinogens heavy metals)reveal no apparent harm to human body, while Pb exhibits certain harm. The carcinogenic risk index of Cd and Ni for children and adult are both within the acceptable range, while Cr brought about greater carcinogenic risk.
