【摘要】：目的了解陕西地区蔬菜中砷和汞的污染状况及评价其暴露量。方法根据陕西省污染物监测计划,对近3年来采集的蔬菜样品进行测定,对测定结果进行统计分析,并对陕西10个地区居民通过食用蔬菜途径所致砷和汞的暴露量进行计算评估。结果 2013—2015年,共采集蔬菜样品1 175份,汞的平均含量为0.002 54 mg/kg,砷的平均含量为0.0271 mg/kg,陕西居民经食用蔬菜所致砷和汞的暴露量分别为10.7和0.999[×10-5mg/(kg·d)],占每日可耐受摄入量(TDI)比例分别为5.0%、1.8%,均低于世界卫生组织食品添加剂联合专家委员会制定的暂定TDI。结论陕西地区蔬菜不存在明显的砷、汞污染情况,居民通过食用蔬菜途径所致砷和汞的暴露量在安全范围内。
[Abstract]:Objective to understand the pollution status of arsenic and mercury in vegetables in Shaanxi Province and to evaluate their exposure. Methods according to the pollution monitoring plan of Shaanxi Province, the samples of vegetables collected in recent three years were determined. The results were statistically analyzed and the exposure of arsenic and mercury to edible vegetables was calculated and evaluated in 10 regions of Shaanxi province. The results showed that the exposure to arsenic and mercury in 10 regions of Shaanxi province was 2013-2015. A total of 1,175 vegetable samples were collected, the average mercury content was 0.002 54 mg / kg and the average arsenic content was 0.0271 mg/kg. The exposure of Shaanxi residents to arsenic and mercury from edible vegetables were 10.7 and 0.999, respectively. [脳 10 ~ (-5) mg / kg 路d), the ratio of TDIs to daily tolerable intakes was 5.0% and 1.8% respectively. Conclusion there is no obvious arsenic and mercury pollution in vegetables in Shaanxi. Exposure to arsenic and mercury by eating vegetables is safe.

【正文快照】： 砷、汞历来是环境与食品监测中的重要部分,砷、汞及其化合物可同过饮食、饮水、呼吸和皮肤接触等多种途径作用于人体[1],其中饮食是人体砷、汞暴露量的主要途径,居民日常膳食中蔬菜的消费量仅次于粮食,所以开展蔬菜中砷、汞含量调查及其暴露量评估的工作是非常有必要。陕西省
