New article: Arsenic and other geogenic contaminants in global groundwater
After two years of work, the article “Arsenic and other geogenic contaminants in global groundwater” has been published in Nature Reviews in Earth and Environment. The authors are SEED researchers Prosun Bhattacharya and Julian Ijumulana, as well as colleagues from 16 universities across the world.
Geogenic groundwater contaminants (GGCs) affect drinking-water availability and safety, with up to 60% of groundwater sources in some regions contaminated by more than recommended concentrations. As a result, an estimated 300–500 million people are at risk of severe health impacts and premature mortality. In this Review article, the authors discuss the sources, occurrences and cycling of arsenic, fluoride, selenium and uranium, which are GGCs with widespread distribution and/or high toxicity.
