TLDR
In this paper, the authors examined the hydrologic and geochemical factors controlling arsenic within the Jianghan Plain, an inland sedimentary basin of the Yangtze River, where arsenic concentrations exhibit strong seasonal variability driven by surface and groundwater mixing.About:

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
Sedimentogenesis and hydrobiogeochemistry of high arsenic Late Pleistocene-Holocene aquifer systems
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.

Arsenic in a groundwater environment in Bangladesh: Occurrence and mobilization
Md. Enamul Huq,Shah Fahad,Zhenfeng Shao,Most. Sinthia Sarven,Imtiaz Ali Khan,Mukhtar Alam,Muhammad Saeed,Hidayat Ullah,Muahmmad Adnan,Shah Saud,Qimin Cheng,Shaukat Ali,Fazli Wahid,Muhammad Zamin,Mian Ahmad Raza,Beena Saeed,Muhammad Riaz,Wasif Ullah Khan +17 more
TL;DR: This review focuses on the occurrence, origin, plausible sources, and mobilization mechanisms of As in the groundwater of Bangladesh to better understand its environmental as well as public health consequences.
Journal ArticleDOI
Review: Safe and sustainable groundwater supply in China
TL;DR: Wang et al. as mentioned in this paper reviewed the changes in China, which have occurred under the impact of rapid economic development, and the effects of economic growth on groundwater systems should be monitored, understood and predicted to better protect and manage groundwater resources for the future.
Advection of Surface-Derived Organic Carbon Fuels Microbial Reduction in Bangladesh Groundwater
Brian J. Mailloux,Elizabeth Trembath-Reichert,J. Cheung,M Watson,Martin Stute,Greg A. Freyer,Andrew Ferguson,Kazi Matin Ahmed,Jahangir Alam,Bruce A. Buchholz,James M. Thomas,Alice C. Layton,Yan Zheng,Benjamin C. Bostick,A. van Geen +14 more
TL;DR: The authors used the radiocarbon (14C) signature of microbial DNA isolated from groundwater samples to determine the relative importance of surface and sediment-derived organic carbon (OC) for aquifer microbial communities.

ATHENA, ARTEMIS, HEPHAESTUS: data analysis for X-ray absorption spectroscopy using IFEFFIT.
Bruce Ravel,Matthew Newville +1 more
TL;DR: A software package for the analysis of X-ray absorption spectroscopy (XAS) data is presented, based on the IFEFFIT library of numerical and XAS algorithms and is written in the Perl programming language using the Perl/Tk graphics toolkit.
Journal ArticleDOI
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.

Comparison of arsenic(V) and arsenic(III) sorption onto iron oxide minerals: implications for arsenic mobility.
Suvasis Dixit,Janet G. Hering +1 more
TL;DR: The sorption data indicate that, under most of the chemical conditions investigated in this study, reduction of As(V) in the presence of HFO or goethite would have only minor effects on or even decrease its mobility in the environment at near-neutral pH conditions.
Journal ArticleDOI
Stability of organic carbon in deep soil layers controlled by fresh carbon supply
TL;DR: It is proposed that a lack of supply of fresh carbon may prevent the decomposition of the organic carbon pool in deep soil layers in response to future changes in temperature.
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.
