Dynamic behaviors of water levels and arsenic concentration in shallow groundwater from the Hetao Basin, Inner Mongolia
TLDR
In this paper, the authors studied the temporal variations in groundwater As concentration of shallow groundwater from the Hetao basin from 2006 to 2010 and found that As contents were well correlated with Fe contents in the sediment samples from the shallow aquifers, and the most plausible explanation for the decoupling between tem- poral variation in As concentration and in Fe concentration was expected to be the reductive desorption of As(V), due to the analogical variation trends between As(III) and total As.About:

Journal ArticleDOI
A review of high arsenic groundwater in Mainland and Taiwan, China: Distribution, characteristics and geochemical processes
TL;DR: The contribution of competitive desorption to high As concentrations is still unknown and remains to be discovered, relative to reductive dissolution of Fe oxides, especially in the inland basins as mentioned in this paper.
Journal ArticleDOI
Arsenic, fluoride and iodine in groundwater of China
Dongguang Wen,Fucun Zhang,Eryong Zhang,Eryong Zhang,Cheng Wang,Shuangbao Han,Yan Zheng,Yan Zheng,Yan Zheng +8 more
TL;DR: Wang et al. as mentioned in this paper reviewed the new understandings gained through these studies, including those published in this special issue, and pointed out the direction for future research that will shed light on safe guarding a long-term supply of low As and F groundwater in these water scarce semi-arid and arid inland basins of north China.
Journal ArticleDOI
Distribution, formation and human-induced evolution of geogenic contaminated groundwater in China: A review.
TL;DR: The sustainability of groundwater usage faces quality problem caused by anthropogenic activity as well as geogenic contamination, which is more significant in northern China due to extensive groundwater usage, arid climate and widespread Holocene strata.
Journal ArticleDOI
Aquifer Arsenic Cycling Induced by Seasonal Hydrologic Changes within the Yangtze River Basin
TL;DR: The results highlight the vulnerability and variability of groundwater resources in the Jianghan Plain and other inland basins within Asia to changing geochemical conditions, both natural and anthropogenic, and reinforce that continued monitoring of wells in high-risk regions is essential.
Journal ArticleDOI
Temporal variation of groundwater level and arsenic concentration at Jianghan Plain, central China
TL;DR: Wang et al. as discussed by the authors collected data from 39 monitoring wells and two rivers in the field monitoring site, Jianghan Plain, to evaluate the temporal variation of groundwater level and chemical composition for As and other constituents.

A review of the source, behaviour and distribution of arsenic in natural waters
TL;DR: The scale of the problem in terms of population exposed to high As concentrations is greatest in the Bengal Basin with more than 40 million people drinking water containing ‘excessive’ As as mentioned in this paper.
Journal ArticleDOI
Arsenic poisoning of Bangladesh groundwater
TL;DR: Sedimentological study of the Ganges alluvial sediments shows that the arsenic derives from the reductive dissolution of arsenic-rich iron oxyhydroxides, which in turn are derived from weathering of base-metal sulphides.

Role of metal-reducing bacteria in arsenic release from Bengal delta sediments

TL;DR: It is shown that anaerobic metal-reducing bacteria can play a key role in the mobilization of arsenic in sediments collected from a contaminated aquifer in West Bengal and that, for the sediments in this study, arsenic release took place after Fe(iii) reduction, rather than occurring simultaneously.

Arsenic contamination of groundwater and drinking water in Vietnam: a human health threat.

TL;DR: The high arsenic concentrations found in the tubewells indicate that several million people consuming untreated groundwater might be at a considerable risk of chronic arsenic poisoning.

Near-Surface Wetland Sediments as a Source of Arsenic Release to Ground Water in Asia
TL;DR: The observation of strong hydrologic influence on arsenic behaviour indicates that release and transport of arsenic are sensitive to continuing and impending anthropogenic disturbances, which will alter the hydraulic regime and/or arsenic source material and, by extension, influence groundwater arsenic concentrations and the future of this health problem.
