饮用水的健康风险是一个世界性的问题。我们最近的研究表明，单独暴露于钡（≤700 µg/L）以及同时暴露于钡（137 µg/L）和砷（225 µg/L）会增加毒性。2011年修订的世卫组织基于健康的饮用水指南保持了砷（10微克/升）和钡（700微克/升）的值，但没有锰、铁和锌等元素。然而，对饮用水和人体样本中钡的研究很少。这项研究表明，在孟加拉国杰索尔居民的尿液、脚趾甲和头发样本中，砷和钡的水平之间存在显著相关性，但与其同源元素（镁、钙和锶）无关。饮用井水中砷和钡的含量与人体尿液、趾甲和头发中砷和钡的含量也有显著相关性。在此基础上，开发了一种高性能、低成本的类水滑石型钡砷吸附剂。吸附剂在1分钟内将孟加拉国和越南井水中的钡和砷含量降低到<7 µg/L。因此，我们已经显示了人体中的砷和钡含量，并提出了一种新的修复系统。
Health risk for well drinking water is a worldwide problem. Our recent studies showed increased toxicity by exposure to barium alone (≤700 µg/L) and coexposure to barium (137 µg/L) and arsenic (225 µg/L). The present edition of WHO health-based guidelines for drinking water revised in 2011 has maintained the values of arsenic (10 µg/L) and barium (700 µg/L), but not elements such as manganese, iron and zinc. Nevertheless, there have been very few studies on barium in drinking water and human samples. This study showed significant correlations between levels of arsenic and barium, but not its homologous elements (magnesium, calcium and strontium), in urine, toenail and hair samples obtained from residents of Jessore, Bangladesh. Significant correlation between levels of arsenic and barium in well drinking water and levels in human urine, toenail and hair samples were also observed. Based on these results, a high-performance and low-cost adsorbent composed of a hydrotalcite-like compound for barium and arsenic was developed. The adsorbent reduced levels of barium and arsenic from well water in Bangladesh and Vietnam to <7 µg/L within 1 min. Thus, we have showed levels of arsenic and barium in humans and propose a novel remediation system.
