目的评估我国成人居民膳食中铅暴露量及其健康风险。方法利用2014年全国21类食物中铅含量数据、2002年中国居民营养与健康状况调查和2013年中国居民饮料、饮料酒消费状况调查中的食物消费量数据,采用简单分布评估的方法,计算我国成人膳食中铅暴露水平及其分布情况,并利用暴露限值(MOE)方法对潜在健康风险进行评估。结果虽然我国成人膳食的铅暴露水平总体呈下降趋势,但是我国成人仍有0.61%的个体MOE值≤1。大米及其制品、面粉及其制品、蔬菜和畜肉是我国成人膳食中铅的主要来源,占膳食总暴露量70%以上。结论我国成人居民膳食中铅暴露导致的健康风险较低,但有0.61%的个体健康风险需要关注。
Objective To assess the dietary lead exposure and its health risk in Chinese adult population. Methods Based on the data of lead content in 21 categories of foods nationwide in 2014, the survey on nutrition and health status of Chinese residents in 2002 and the survey on consumption status of beverages, beverages and beverages by Chinese residents in 2013, the method of simple distribution evaluation The level and distribution of lead exposure in adults and potential health risks using the Exposure Limit (MOE) method. Results Although the level of lead exposure in adults in China generally showed a decreasing trend, 0.61% of our adult population still had MOE ≤1. Rice and its products, flour and its products, vegetables and meat are the main sources of lead in our adult diet, accounting for more than 70% of the total dietary exposure. Conclusion The dietary exposure to lead in our country leads to a lower health risk. However, there is a 0.61% risk of individual health concern.
