超过60，000，000孟加拉国人饮用的水中含有一种或多种不安全的元素。我们在这项研究中的目的是评估和改善孟加拉国西部的饮用水检测和处理计划。我们从孟加拉国西部的四个社区抽取了地下水样本，以确定砷、硼、钡、铬、铁、锰、钼、镍、铅、锑、硒、铀和锌的分布，并确定pH值。浓度超过世界卫生组织（WHO）基于健康的饮用水指南的管井威尔斯的百分比为：锰78%，铀48%，As为33%，Pb为1%，Ni为1%，Cr为1%。个别管井威尔斯的锰和砷或锰和铀的浓度往往不安全。他们很少有不安全的浓度都作为和U。这些结果表明，正在进行的项目，确定安全的饮用水供应，测试每一个管井，只有砷不会确保安全浓度的锰，铀，铅，镍，铬，和可能的其他元素。为了最大限度地提高效率，孟加拉国的饮用水检测应分三步完成：1）必须对所有管威尔斯井进行采样并检测砷; 2）如果样本符合世卫组织的砷指南，则应重新检测锰和铀; 3）如果样本符合世卫组织的砷、锰和铀指南，则应重新检测B、Ba、Cr、Mo、Ni和Pb。应考虑将所有安全管井威尔斯用作公共饮用水供应。
More than 60,000,000 Bangladeshis are drinking water with unsafe concentrations of one or more elements. Our aims in this study were to evaluate and improve the drinking water testing and treatment plans for western Bangladesh. We sampled groundwater from four neighborhoods in western Bangladesh to determine the distributions of arsenic, boron, barium, chromium, iron, manganese, molybdenum, nickel, lead, antimony, selenium, uranium, and zinc, and to determine pH. The percentages of tube wells that had concentrations exceeding World Health Organization (WHO) health-based drinking water guidelines were 78% for Mn, 48% for U, 33% for As, 1% for Pb, 1% for Ni, and 1% for Cr. Individual tube wells often had unsafe concentrations of both Mn and As or both Mn and U. They seldom had unsafe concentrations of both As and U. These results suggest that the ongoing program of identifying safe drinking water supplies by testing every tube well for As only will not ensure safe concentrations of Mn, U, Pb, Ni, Cr, and possibly other elements. To maximize efficiency, drinking water testing in Bangladesh should be completed in three steps: 1) all tube wells must be sampled and tested for As; 2) if a sample meets the WHO guideline for As, then it should be retested for Mn and U; 3) if a sample meets the WHO guidelines for As, Mn, and U, then it should be retested for B, Ba, Cr, Mo, Ni, and Pb. All safe tube wells should be considered for use as public drinking water supplies.
