晋中市部分蔬菜中重金属含量及其健康风险

为研究蔬菜重金属污染状况和蔬菜安全水平,对晋中市10种蔬菜中Hg、Pb、Cd、Cr、As等5种重金属元素的含量进行了测定,并参照国际放射防护委员会（ICRP）给出的限定值为标准,对重金属含量超标的蔬菜进行了健康风险评价。结果表明：晋中市部分蔬菜中铅含量超过国家限定值（GB 18406.1-2001）,风险评价结果表明存在Pb污染的蔬菜对人体的健康风险为1.271×10-7·a-1,低于国际放射防护委员会ICPR标准,表明食用蔬菜所引起的健康风险甚微,不会对暴露人群构成明显的危害。

Contents of Heavy Metals in Some Vegetables and Their Potential Risks to Human Health in Jinzhong City

In order to find the vegetable pollution situation and vegetable safe level of heavy metal, We analyzed heavy metals in 10 kinds vegetables from Jinzhong City. According to the standards of International Commission on radiological Protection(ICRP), We assessmented the health risk of vegetables which were above limits.The results of the analysis indicate that some vegetables content of lead exceeded the National limit(GB18406.1-2001).the annual non-carcinogenic risks of vegetables polluted by Pb to individual human health were 1.271×10-7·a-1,were lower than the standards of International Commission on radiological Protection(ICRP),which indicated that the health risk via vegetable consumption in Jinzhong city was relative low. It will not pose a significant risk to exposed populations.
