某地下水水源地重金属元素健康风险研究

Study on Health Risk of Heavy Metal Elements in a Groundwater Source

通过电感耦合等离子体质谱仪(ICP-MS)对采自某地下水水源地共38个水样品中的8种重金属元素(Pb,Cu,Zn,Cd,Ni,Mn,Cr和Fe)进行含量分析,并使用USEPA推荐的健康风险评价模型对致癌与非致癌健康风险进行了研究.结果表明,该水源Cr与Cd的致癌健康风险水平较高,需要引起重视,尤其是Cr;由Cu,Pb,Zn,Cd,Ni,Mn,Cr和Fe造成的非致癌健康风险处于较低水平,不会对人体造成显著危害.

A total of 38 groundwater samples were collected from groundwater drinking water sources and were analyzed for 8kinds of heavy metal elements contents including Pb,Cu,Zn,Cd,Ni,Mn,Cr and Fe by using Inductively Coupled Plasma Mass Spectrometry(ICP-MS)analysis.The carcinogenic risk and non-carcinogenic risk assessment were conducted by using the USEPA health risk assessment model,and the results indicated that the carcinogenic risk of Cr and Cd should be paid more attention,especially for Cr.The non-carcinogenic risk of Cr,Cu,Pb,Zn,Cd,Ni,Mn,Cr and Fe were at low level and may not cause significant damage to human beings.
