摘要:

利用单项污染指数法和国际推荐的健康风险评价方法对该市售部分叶菜类蔬菜样品中铅镉的污染状况与其导致的健康风险进行分析和评价。叶菜类蔬菜铅镉含量超标率为12.39%，单项污染指数值均低于2.0；Pb为3.99×10-8（a-1）～1.80×10-7（a-1），总和为9.55×10-7（a-1）。Cd的年平均个人健康风险值范围为1.53×10-5（a-1）～4.09×10-5（a-1），总和为2.13×10-4（a-1）；该市售部分叶菜类蔬菜Pb超标；单项污染指数评价结果说明该市售叶菜类蔬菜基本属于优良及安全范围。从健康风险指数来看，该市售叶菜类蔬菜中铅镉对人体健康危害的个人年风险处于安全水平。但其个人年健康风险总和高于ICRP推荐的标准值，说明该市居民饮食摄入蔬菜的Pb、Cd已具有潜在的健康威胁。

Abstract:

Utilize single pollution index and international health risk assessment method recommended by the health status of a commercial part of the risk of contamination of leafy vegetables to their lead and cadmium in the sample cause analysis and evaluated. leafy vegetables cadmium content of lead exceeding the rate of 12.39%；single pollution index values were lower than 2.0；Pb is 3.99×10-8（a-1）~1.80×10-7（a-1），the sum of 9.55×10-7（a-1）.The annual average value range of personal health risks Cd is 1.53×10-5（a-1）~4.09×10-5（a-1），the sum of 2.13×10-4（a-1）. The commercial part leafy vegetables Pb exceeded；single pollution index shows that the results of the evaluation of commercially available leafy vegetables are excellent and basic safety range；from health risks index，the commercially available lead and cadmium in leafy vegetables hazards to human health personal annual risk at a safe level.But it was a healthy sum of the individual risk than ICRP recommended standard values.This shows that the city's residents dietary intake of vegetables，Pb，Cd has a potential health threat.
