Arsenic and Heavy Metal Remediation in Water, Soil, and Mine Drainage
This community investigates how arsenic and other heavy metals move through groundwater, soil, and industrial waste, and develops methods to remove them from drinking water or immobilize them in the environment.
The research focuses heavily on the chemistry of arsenic (specifically As(III) and arsenate) and its interaction with iron and manganese oxides. Key activities include adsorption and removal of arsenic from aqueous solutions and groundwater, remediation of acid mine drainage, and assessing health risks associated with contaminated drinking water. A significant portion of the work examines the role of organic matter and redox interfaces in mobilizing or stabilizing metals in paddy soils and natural aquifers. The methods span from adsorption using iron oxides and manganese oxides to biological and chemical treatment processes for wastewater and mine water.
The largest share of the community's output is found in arsenic research, accounting for 10.9% of all tracked arsenic papers, with 18,050 papers in this group. Iron research contributes the second-largest share at 1.9% (7,599 papers), followed by manganese at 2.4% (3,548 papers).
The community comprises 31,274 papers, publishing most frequently in the Journal of Hazardous Materials, Environmental Science & Technology, and Chemosphere.
Recent work continues to explore the mechanisms of arsenic and cadmium mobility during mineral transformations, such as ferrihydrite transformation and layered double hydroxide interactions. New studies also examine the use of metal-organic frameworks for water treatment and the microbial drivers of arsenic accumulation in rice grains.
