摘　　要：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 evaluate Chinese adult dietary lead intake level and its potential health risks. Methods Concentration data of lead of 21 food categories in 2014,food consumption data from Chinese Nutrition and Health Survey2002,and beverage consumption data from Chinese Beverage and Alcholic Beverage Consumption Survey 2013 were used to calculate dietary exposure of lead among Chinese adult population by simple distribution model. The margin of exposure（ MOE） method was adopted to assess the potential health risks of dietary lead exposure. Results The MOE values of mean,median and high consumption（ P97. 5） dietary lead exposure among all adults were over 1,so did the values among different areas and age-gender specified population. However,there were 0. 61% of adults whose MOE values were less than or equal to 1. It was indicated that the main sources of dietary lead were rice and its products,flour and its product,vegetables and meat,which contributed more than 70% of total dietary lead exposure. Conclusion It suggested that the potential health risks caused by dietary lead exposure in Chinese adult population was of low concern,but there still were0. 61% of the population need further consideration.
