| 摘 要： | 采样分析典型地砷病区域——内蒙古河套地区地下水、地表水和自来水中砷含量和形态,研究河套地区水体中砷分布状况,并采集山西山阴县大营村(地下水)和山东招远地区水样(地表水、地下水),以用于污染特性比较和源解析。结果发现,内蒙古河套地区和山西省山阴县大营村作为生活饮用水的地下水中砷含量超标率较高,其中内蒙古临河区狼山镇先锋七社和山西大营村地下水砷含量平均值分别为368.9和443.5μg.L-1,分别有75%和100%的水样超过GB 5749—2006《生活饮用水卫生标准》中农村小型集中和分散式供水砷含量限值。内蒙古五原县乃日乡的175个水样中,也有59%的地下水样砷含量高于50μg.L-1,且砷形态主要以无机砷为主。河套地区地表水水样砷含量大部分在50μg.L-1以下,部分自来水(水源为地下水)样砷含量超过生活饮用水标准。

| Abstract: | Samples were taken from different waterbodies(groundwater,surface water and tap water) in the Hetao Plain,Inner Mongolia,for analysis of the content and species of As to study distribution of As in the waterbodies in that typical area of endemic As disease.Samples of groundwater at Daying Village,Shanyin County of Shanxi and of surface water and groundwater at Zhaoyuan District of Shandong were also collected for comparison of pollution features and analysis of sources.Total As was determined with inductive... |
