Arsenic in the geo-environment: A review of sources, geochemical processes, toxicity and removal technologies

N. Janardhana Raju

Summary: Arsenic contamination in groundwater is a global concern for human health through drinking and irrigation practices. The review in this paper covers sources, processes, health effects, and treatment technologies for arsenic removal. The most serious known arsenic contamination problem with the largest population at risk is found in Bangladesh and West Bengal state in India.

In situ arsenic speciation at the soil/water interface of saline-alkaline lakes of the Pantanal, Brazil: A DGT-based approach

Jose Lucas Martins Viana et al.

Summary: Arsenic (As) is a naturally occurring element with toxicity towards living organisms, commonly found as As (III) and As(V). High concentrations were found in saline-alkaline lakes of the Pantanal (Brazil), where labile As(III) dominated arsenic speciation at the soil/water interface. The study highlights the importance of passive sampling techniques in metal/metalloid speciation analysis in environmental studies.

A Novel In Situ Method for Simultaneously and Selectively Measuring AsIII, SbIII, and SeIV in Freshwater and Soils

Wen Fang et al.

Summary: In this study, a novel method based on aminopropyl and mercaptopropyl bi-functionalized mesoporous silica spheres was developed to quantitatively measure three typical/toxic but difficult to measure inorganic species. The method showed stable and accurate predictions of these species in environmental monitoring and chemical imaging of soil solute fluxes.

Effectiveness and limitation of A-nZVI for restoration of a highly As-contaminated soil

Liang Li et al.

Summary: The study investigated the effectiveness of air-stabilized nano zero-valent iron (A-nZVI) in reducing soil arsenic solubility and leachability, as well as its impact on soil biological function. Results showed that A-nZVI had a high sorption capacity for arsenite and arsenate, leading to a significant decline in soil arsenic solubility. Furthermore, A-nZVI was found to promote the recovery of soil biological functions and improve soil health, making it a crucial factor in the restoration of highly degraded, arsenic-contaminated soil.

Depletion of bioavailable As/Cd with rice plant from paddy soils of high contamination risk

Lu Yan et al.

Summary: The co-uptake and high accumulation of arsenic and cadmium by rice poses a threat to public health. However, a field trial showed that removing rice roots after efficient extraction of arsenic and cadmium from paddy soil can significantly reduce the levels of these toxic elements in both soil and rice, contributing to rice safety in contaminated areas.

Arsenic biogeochemical cycling in paddy soil-rice system: Interaction with various factors, amendments and mineral nutrients

Muhammad Mahroz Hussain et al.

Summary: Arsenic contamination in paddy soil poses a global environmental and health issue, with key factors including As speciation and accumulation, pH, iron oxides, organic matter, microbial species, etc. Rice plants have a higher uptake of arsenile (As(III)) compared to other food crops, and different mineral nutrients and amendments can mitigate the transfer of As to rice grain.
