Arsenic and Antimony Contamination in Groundwater, Soils, and Rice Systems
This research community investigates the chemical behavior, health risks, and removal of arsenic and antimony from drinking water, agricultural soils, and rice crops.
The work focuses heavily on the speciation of arsenic (particularly As(III) and As(V)) and antimony in aqueous solutions and paddy soils. Recurring themes include the interaction of these metalloids with iron oxides and organic matter, which governs their mobility and accumulation in Oryza sativa (rice). Practical applications involve adsorption and treatment technologies for drinking water and wastewater, while a significant portion of the research assesses human health risks associated with groundwater and soil contamination. The community also examines the role of acid mine drainage as a source of these contaminants and the mechanisms of their stabilization or mobilization in flooded agricultural environments.
Arsenic research is the largest share of this community's output, accounting for 25.0% of all arsenic research tracked, with 20,965 papers in this group. Antimony is the second most significant element, representing 10.3% of antimony research with 4,245 papers. Iron contributes 2.0% of its research to this community, with 2,711 papers.
The community comprises 42,120 papers, publishing most frequently in the Journal of Hazardous Materials, Chemosphere, and Environmental Science & Technology.
Recent work continues to focus on the immobilization of As(III) in paddy fields using nitrate and schwertmannite, the electrocatalytic removal of antimony from wastewater, and the formation and function of iron plaque in paddy soils.
