TL;DR: Hydrochemical data and sulfur isotope ratios of sulfate are used to better understand the conditions that are likely to control arsenic mobilization and are consistent with the possibility that the traditional models of arsenic mobilization are correct.

TL;DR: In this paper, the authors studied the sources and mobilization processes responsible for arsenic enrichment in groundwater in the central part of Datong Basin where serious arsenic poisoning cases have been reported, hydrochemical characteristics of the groundwater and the geochemical and mineralogical features of the aquifer sediments were studied.

TL;DR: In this article, the authors investigated the origin and the geochemical mechanisms of fluoride enrichment in groundwater at Datong Basin, and found that the fluoride concentration in the groundwater samples from 70 wells selected for this study ranges from 0.1 to 8.3 mg/L (mean 2.2mg/L), with 51% of the samples containing fluoride concentrations exceeding the WHO drinking water guideline value of 1.5 mg/l.

TL;DR: In this article, the authors studied the geogenic enrichment of arsenic (As) in groundwater, which has been a topic of worldwide concern over the past several decades due to the severe health threat to an estimated over one hundred million people.

TL;DR: The results suggest that bedrocks such as Carboniferous and Permian sedimentary rocks, especially the coal-bearing strata which have higher U contents at the west mountain areas may also account for the abnormally high levels of U in groundwater.
