摘要
目的分析山西省地方性砷中毒(地砷病)病人饮水和当地自产粮食中的砷含量,为砷中毒防治研究提供科学依据。方法在山西省地砷病病区随机抽取17个村的189名地砷病病人作为调查对象,入户采集所有调查对象的饮用水和当地自产粮食。样品中砷浓度测定用HPLC-ICP-MS定量检测。结果在随机抽取的134份水样中,砷超标率达64.9%,中位数值为91.43μg/L。125份粮食样品中,砷超标率达44.8%,中位数值为0.65 mg/kg。结论调查表明,地砷病病区饮水和粮食中砷浓度均高,地砷病病人通过饮用高砷井水和食用高砷粮食暴露于外环境中砷而致慢性砷中毒。
Objective To investigate the arsenic levels in drinking water and food of endemic arsenism patients in Shanxi province, Methods 189 eases were randomly selected in 17 countries of endemic arsenism in Shanxi province, the drinking water and food planted locally were collected. The content of arsenic in drinking water and food were quantitatively determined by HPLC - ICP - MS detected in Japan. Results There are 64.9% samples above the arsenic level（50μg/L） of national drinking water and the median value of arsenic in drinking water is 91.43~g/L in 134 water samples. There are 44.8% samples above the arsenic level of national food and the median value of arsenic in food is 0.65 mg/kg in 125 food samples. Conclusions The arsenic in drinking water and food were both high in endemic arsenism area of Shanxi province. The patients of endemic arsenism intake arsenic through not only drinking water but also food.
