Geogenic molybdenum in ground and drinking water

一般来说，钼在饮用水中的浓度远低于健康问题，到目前为止，世界卫生组织（WHO）还没有建立一个指导值，但发布了一项建议，即饮用水中的钼不应超过70 μg/L。因此，最近在佛罗里达中部发现的地下水钼（Mo）浓度超过5000微克/升，引起了人们的关注。在那里，钼是天然存在的（地质），但由于含水层中的物理化学条件的人为扰动而释放。这种由地质元素引起的污染是一个全球性的公共卫生问题。特别是孟加拉国和西孟加拉目前的砷灾难性问题成为报纸和科学杂志的头版报道。虽然毒性比砷低得多，钼可能被证明是类似的问题，特别是在含水层的海洋起源，钼已经自然higher.To更好地了解的可能性，由地质钼的多学科的方法来评估其可能的释放从几个含水层的海洋起源。最终目标将是通过结合（地球）化学，水文地质学和矿物学分析，以及在反应运输模型框架中对这些结果进行量化，对Mo的动员有一个全面的了解。

Generally Mo occurs in drinking water at concentrations well below those of health concern and thus far the World Health Organization (WHO) has not established a guideline value, but published a recommendation that Mo should not exceed 70 μg/L in drinking water. Thus, the recent discovery of groundwater molybdenum (Mo) concentrations of more than 5000 µg/L in Central Florida raises concern. There the Mo is naturally occurring (geogenic), but released due to anthropogenic perturbations of the physicochemical conditions in the aquifer. This type of anthropogenic-induced contamination by geogenic elements is a public health issue worldwide. In particular the ongoing catastrophic problems with arsenic (As) in Bangladesh and West Bengal are front-page stories in newspapers and scientific journals. Although much less toxic than As, Mo may prove to be of similar concern, particularly in aquifers of marine origin where Mo is already naturally elevated.To better understand the possibility of anthropogenic-induced contamination by geogenic Mo a multidisciplinary approach is proposed to evaluate its possible release from several aquifers of marine origin. The ultimate goal will be to develop an integral understanding of Mo mobilization through a combination of (geo)chemical, hydrogeological and mineralogical analyses together with the quantification of these results in a reactive transport model framework.
