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 …

Element specificity is one of the key factors underlying the widespread use and acceptance
of X-ray absorption spectroscopy (XAS) as a research tool in the environmental and geo …

Groundwater drawn daily from shallow alluvial sands by millions of wells over large areas of
south and southeast Asia exposes an estimated population of over a hundred million people …

Sediments from the Red River and from an adjacent floodplain aquifer were investigated
with respect to the speciation of Fe and As in the solid phase, to trace the diagenetic …

Abstract Aquifers on the Red River flood plain with burial ages ranging from 500 to 6000
years show, with increasing age, the following changes in solute concentrations; a decrease …

The adsorption of arsenic onto aquifer sediment from the Red River floodplain, Vietnam, was
determined in a series of batch experiments. Due to water supply pumping, river water …

A substantial amount of sulfate is often supplied in paddy fields with concomitant
applications of chemical fertilizers and manure for rice growth. It is unclear how solubility …

Contamination of arsenic (As) in water, especially groundwater, has been recognized as a
major problem across the world. The presence of arsenic in groundwater has become a …

Water-sediment interactions were investigated in arsenic contaminated Holocene aquifers of
the Red River floodplain, Vietnam, in order to elucidate the origin of the spatial variability in …

Rice (Oryza sativa L.) can readily accumulate arsenic (As), owing to its high capacity to take
up As and special flooding cultivation, which poses a potential risk to human health …
