由于在全国范围内进行了地毯式实地测试，孟加拉国数百万人可能已经改用符合饮用水中砷含量为50 μ g/L的当地标准的水井。因此，了解这些井中的砷浓度是否会随时间变化是很重要的。为了解决这个问题，我们在这里报告了从一套20个管井中收集的时间序列样本的精确地下水As分析
Millions of people in Bangladesh have probably switched their water consumption to wells that meet the local standard for As in drinking water of 50 mu g/L as a result of blanket field testing throughout the country. It is therefore important to know if As concentrations in those wells could change over time. To address this issue, we report here precise groundwater As analyses for time-series samples collected from a suite of 20 tube wells containing
