摘要
目的了解绍兴地区不同人群膳食中铅、镉和总汞的摄入量,评估绍兴地区膳食中铅、镉和总汞的安全性。方法对绍兴地区食品中铅、镉和总汞含量进行监测,结合2008年绍兴市居民膳食消费量调查结果,对绍兴地区不同人群膳食中铅、镉和总汞的暴露水平进行评估。结果不同年龄和性别人群膳食中铅的每周平均暴露量为5.26-13.1μg/kg BW,占原PTWI的21.0%-52.4%,全人群膳食中铅的平均暴露限值（MOE）为1.02;镉的每月平均暴露量为16.0-39.4μg/kg BW,占PTMI的64.0%-157.6%,2-6岁和7-17岁年龄组男性、2-6岁年龄组女性膳食中镉暴露水平均超过了PTMI限值（25μg/kg BW）;总汞的每周平均暴露量为0.67-2.02μg/kg BW,占PTWI的16.8%-50.5%。膳食中铅、镉和总汞的主要来源均为米及其制品和鱼虾类食品。结论绍兴地区居民膳食中总汞暴露水平是安全的,但膳食中铅和镉暴露水平较高,尤其是18岁以下人群,需加强相关食品中铅和镉的监测及膳食指导。
Objective To obtain the intakes of lead, cadmium and total mercury from food in different populations in Shaoxing, and to evaluate the risk of lead, cadmium and total mercury from food. Methods The food samples were collected and the contents of lead, cadmium and total mercury were detected, the exposure levels of lead, cadmium and total mercury from food in Shaoxing were assessed by combination with the survey results of dietary consumption of residents in Shaoxing in 2008. Results The weekly exposure level of lead ranged from 5.26 to 13. 1 p.g/kg BW, which accounted for 21.0%-52.4% of the FTWI in different gender and age groups, and the MOE value of lead was 1.02 ; the monthly exposure level of cadmium ranged from 16. 0 to 39. 4 μg/kg BW, which accounted for 64. 0% -157.6% of the PTMI in different gender and age groups, the dietary cadmium exposure of men aged 2-6 and 7-17 and women aged 2-6 exceeded the PTMI （25 μg/kg BW） ; the weekly exposure level of total mercury ranged from 0. 67 to 2. 02 μg/kg BW, which accounted for 16. 8% -50. 5% of the PTWI in different gender and age groups. Conclusion The dietary exposure levels of total mercury were safe, but the dietary exposure levels of lead and cadmium were relatively high, especially for the population under 18 years of age. It was necessary to strengthen the lead and cadmium surveillance in related food and provide dietary guidance for residents.
