龟苓膏中重金属健康风险评价

Health Risk Assessment of Heavy Metals in Guilinggao

试验借鉴美国环保署推荐的健康风险评价模型,建立龟苓膏产品中重金属的健康风险评价模型,据此评估食用龟苓膏产品的健康风险度的大小。研究结果显示,当日均食用龟苓膏为10.83 g时,铬、锌和镉的健康风险指数(HQ)分别为3.4×10^(-5),6.3×10^(-4)和3.3×10^(-3),该3种金属的综合健康风险指数(HI)为4.0×10^(-3),健康风险指数均小于1。因此,认为铬、锌和镉对暴露人群没有明显的健康风险。研究成果可为食品质量监测管理执法部门提供科学理论依据,且为DB 45/391—2011"地理标志产品梧州龟苓膏"日后修订提供技术支撑,并为应对龟苓膏突发重金属污染事故提供数据积累和技术储备。

In order to assess the size of the health risks of Guilinggao, the heavy metals health risk assessment model associated in Guilinggao was established with United States Environment Protection Agency （USEPA） health risk assessment model. The result showed that, the HQ of Cr, Zn and Cd was respectively 3.4×10^-5, 6.3 × 10^-4 and 3.3 ×10^-3, and the HI was 4.0×10^-3, when daily intake of Guilinggao was 10.83 g. The health risk value was less than 1, so it belonged to the low risk level. This research achievement could provide scientific basis for the department of food quality supervision and to offer a technological support for revising DB 45/391-2011 ＂Product of geographical indication-Wuzhou Guilinggao＂ in the future. It also offered data accumulation and technical reserve for coping with heavy metals pollution accident of Guilinggao.
