Geochemical controls on arsenic and rare earth elements approximately along a groundwater flow path in the shallow aquifer of the Hetao Basin, Inner Mongolia
TLDR
In this paper, groundwaters and sediments were sampled approximately along a groundwater flow path in the shallow aquifer of the Hetao Basin, Inner Mongolia, where groundwater evolves from Ca-HCO3-SO4 through Mg-Ca-H CO3-Cl to Na-Cl-HO3 from the recharge zone to the discharge.About:

Groundwater Arsenic Contamination Throughout China
Luis Rodríguez-Lado,Guifan Sun,Michael Berg,Qiang Zhang,Hanbin Xue,Quanmei Zheng,C. Annette Johnson +6 more
TL;DR: A statistical risk model is developed that classifies safe and unsafe areas with respect to geogenic arsenic contamination in China, using the threshold of 10 micrograms per liter, the World Health Organization guideline and current Chinese standard for drinking water.

Sources, behaviour, and environmental and human health risks of high-technology rare earth elements as emerging contaminants.
Willis Gwenzi,Lynda Mangori,Concilia Danha,Nhamo Chaukura,Nothando Dunjana,Edmond Sanganyado +5 more
TL;DR: A conceptual framework and possible mitigation measures to minimize health risks are highlighted and future research is needed to better understand sources, environmental behaviour, ecotoxicology, and human epidemiology.
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.

Natural arsenic in global groundwaters: distribution and geochemical triggers for mobilization
Indika Herath,Indika Herath,Meththika Vithanage,Meththika Vithanage,Jochen Bundschuh,Jyoti Prakash Maity,Jyoti Prakash Maity,Prosun Bhattacharya,Prosun Bhattacharya +8 more
TL;DR: In this article, the authors present an overview of the natural geochemical processes that mobilize As from aquifer sediments into groundwater and provide a concise description of the distribution of As in different global groundwater systems, with an emphasis on the highly vulnerable regions of Southeast Asia, the USA, Latin America, and Europe.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

User's guide to PHREEQC (Version 2)-a computer program for speciation, batch-reaction, one-dimensional transport, and inverse geochemical calculations
David L. Parkhurst,C.A.J. Appelo +1 more
TL;DR: PHREEQC as discussed by the authors is a C program written in the C programming language that is designed to perform a wide variety of low-temperature aqueous geochemical calculations.

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.
