Arsenic (As) is a ubiquitous element found in the atmosphere, soils and rocks, natural waters
and organisms. It is one of the most toxic elements and has been classified as a human …

Groundwater with an excessive level of Arsenic (As) is a threat to human health. In
Bangladesh, out of 64 districts, the groundwater of 50 and 59 districts contains As exceeding …

Abstract Datong Basin in China is a typical arid–semiarid inland basin, with high levels and
wide distributions of arsenic (As), fluoride (F−), and iodine (I). To better understand the …

We reviewed over 226 studies dealing with arsenic (As) in water bodies (124 sites or
regions; 5,834 samples), soils (44; 2,700), sediments (56; 765), rocks (6; 85), mine waste …

Geogenic enrichment of arsenic (As) in groundwater has been a topic of worldwide concern
over the past several decades due to the severe health threat to an estimated over one …

Massive amounts of marine sedimentary materials with geogenic heavy metal (loids) are
excavated by the subsurface construction projects and then exposed to weathering …

Recent discoveries on arsenic (As) biogeochemistry in aquifer-sediment system have
strongly improved our understanding of As enrichment mechanisms in groundwater. We …

Organoiodine compounds (OICs) are the dominant iodine species in groundwater systems.
However, molecular mechanisms underlying the geochemical formation of geogenic OICs …

Groundwater with high arsenic (As) content seriously threatens human life and health.
Drinking high-As groundwater for a long time will lead to various pathological changes such …

Iron (hydr) oxides are effective sorbents of arsenic that undergo reductive dissolution when
exposed to dissolved sulfide, which significantly impacts the movement and repartition of …
