In this article, the author analyzed arsenic and selenium for drinking water at Xi'an peripheral locality 11 sampling point and found that the arsenic content in drinking water is lower in south and east of Xi'an. In Hu county area west of Xi'an arsenic content in drin king water is higher than other areas obviously and has achieved 0.047mg/L, approaching the mild pollution standard.

摘 要：通过对西安周边地区11个采样点饮用水中砷含量的调查分析，结果表明西安南部秦岭地区和西安东部的饮用水中砷含量较低，西安西部户县地区砷的含量明显高于其他地区，达到了0.047 mg/L，已基本上接近了轻度污染的标准。
