一九七九年,我们对西安地区工业自备井水质进行了普查,发现砷超标检出率较高,污染面积较大。为进一步掌握西安地区工业井井水砷的富集程度及规律,在七九年工作的基础上,对砷检出值>0.02mg/L 的106眼工业井(包括收集资料的在内)作了采样分析。这些井分布在不同的地税单元上(详见表1)。
In 1979, we surveyed the quality of industrial-owned wells in Xi’an and found that the detection rate of arsenic exceeded the standard and the pollution area was relatively large. In order to further understand the degree and regularity of enrichment of industrial arsenic in industrial wells in Xi’an, based on the work of 1979, 106 industrial wells (including data collection) with arsenic detection value of> 0.02 mg / L Sampling analysis. These wells are distributed in different tax units (see Table 1 for details).
