    摘要:

    目的 掌握吉林省主要食品中砷污染水平,评估吉林省居民砷暴露风险及对人体潜在的健康危害。 方法 2012—2017年吉林省居民主要食品中砷的含量数据来自国家食品风险监测,共11种类别4 532份样品。食物消费量的数据来自2012年吉林省居民营养与健康调查。采用确定性评估方法,结合无机砷的原暂定每周可耐受摄入量(PTWI)和暴露边距(MOE),评价吉林省居民膳食中砷暴露情况。结果 11类食品中砷平均含量为0.030 mg/kg,谷物类、蔬菜类和水产类是膳食中砷的主要来源,三者贡献率之和为76.59%,其中谷物类贡献率高达54.44%。10个不同性别-年龄组平均摄入量为0.73~1.31 μg/kg BW,一般人群暴露量MOE均>1。 结论 吉林省居民膳食中砷暴露风险总体上是安全的。

    Abstract:

    Objective To analyze the arsenic level in main foods, and assess the risk of dietary exposure of inhabitants in Jilin Province. Methods Arsenic concentration data were obtained from the national food contamination program during 2012-2017. Food samples (n=4 532) were collected from 11 food categories in Jilin Province. Consumption data were derived from Jilin provincial nutrition and health survey in 2012. The provisional tolerable weekly intake (PTWI) and margin of exposure (MOE) were used to estimate dietary arsenic exposure of inhabitants in Jilin Province. Results The average concentration of arsenic in 11 categories of food was 0.030 mg/kg. Cereals, vegetables and aquatic products were the main source of dietary arsenic exposure. The contribution rate of the three was 76.59%, of which cereal contributed 54.44%.Dietary arsenic exposure of different age-gender population groups was in the range of 0.73-1.31 μg/kg BW. The MOE of mean dietary arsenic exposure was above 1. Conclusion The status of arsenic exposure of the inhabitants in Jilin Province was safe.
