A review of the source, behaviour and distribution of arsenic in natural waters
The range of As concentrations found in natural waters is large, ranging from less than 0.5
μg l− 1 to more than 5000 μg l− 1. Typical concentrations in freshwater are less than 10 μg l …

Chemical sequential extraction for metal partitioning in environmental solid samples.
A comprehensive review of the sequential extraction schemes for metal fractionation in
environmental samples (ie, sediment, soil, sewage sludge, fly ash, etc.) is presented. The …

Arsenic mobility and groundwater extraction in Bangladesh
High levels of arsenic in well water are causing widespread poisoning in Bangladesh. In a
typical aquifer in southern Bangladesh, chemical data imply that arsenic mobilization is …

Molecular evidence of arsenic mobility linked to biodegradable organic matter
Molecular characteristics of natural organic matter (NOM) and their potential connections to
arsenic enrichment processes remain poorly understood. Here, we examine dissolved …

Impact of iron and sulfur cycling on the bioavailability of cadmium and arsenic in co-contaminated paddy soil
Y Yin, Y Wang, C Ding, Z Zhou, X Tang, L He… - Journal of Hazardous …, 2024 - Elsevier
The biogeochemical cycling of iron (Fe) or sulfur (S) in paddy soil influences the cadmium
(Cd) and arsenic (As) migration. However, the influence of coupled reduction effects and …

The removal of arsenic from water using natural iron oxide minerals
The contamination of groundwater with arsenic is a serious health issue in many parts of the
world. Although iron has been shown to be effective at removal of arsenic from water, there …

Arsenic (V) adsorption from aqueous solution onto goethite, hematite, magnetite and zero-valent iron: Effects of pH, concentration and reversibility
In this paper, adsorption of arsenic (V) was studied under different physico-chemical
conditions onto four commercial adsorbents: hematite, goethite, magnetite and zero-valent …

Arsenic removal with iron (II) and iron (III) in waters with high silicate and phosphate concentrations
Arsenic removal by passive treatment, in which naturally present Fe (II) is oxidized by
aeration and the forming iron (III)(hydr) oxides precipitate with adsorbed arsenic, is the …

Effects of denitrification on speciation and redistribution of arsenic in estuarine sediments
Microbially-mediated redox processes involving arsenic (As) and its host minerals
significantly contribute to the mobilization of As in estuarine sediments. Despite its …

The influence of sulfur and iron on dissolved arsenic concentrations in the shallow subsurface under changing redox conditions
The chemical speciation of arsenic in sediments and porewaters of aquifers is the critical
factor that determines whether dissolved arsenic accumulates to potentially toxic levels …
