Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, Volume 41, Issue 7, Page 459-469, July 2026.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Multi-Component Antioxidative System and Robust Carbohydrate Status, the Essence of Plant Arsenic Tolerance

Antioxidants, 2020
Arsenic (As) contaminates the food chain and decreases agricultural production through impairing plants, particularly due to oxidative stress. To better understand the As tolerance mechanisms, two contrasting tobacco genotypes: As-sensitive Nicotiana ...

Concentrations of cadmium and arsenic species in rice from production‐scale fields in Arkansas under variable water management

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Rice (Oryza sativa L.) accumulates arsenic when grown under flooded conditions; therefore, alternative water management strategies have shown promise in decreasing grain arsenic. We analyzed polished white rice grain from 103 field‐years of production for arsenic and cadmium.

OsPT4 Contributes to Arsenate Uptake and Transport in Rice

Frontiers in Plant Science, 2017
Arsenic (As) is toxic to organisms, and elevated As accumulation in rice (Oryza sativa) grain may pose a significant health risk to humans. The predominant form of As in soil under aerobic conditions is As(V), which has a chemical structure similar to ...

Microbial Ecology of the Heterogeneous Terrestrial Deep Biosphere Over 4 years in the Deep Mine Microbial Observatory (DeMMO)

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The deep continental subsurface hosts a large, diverse, and poorly characterized microbiome. The geochemistry and microbiology of deep subsurface sites are closely linked and influenced by geological, hydrological, and anthropogenic factors. The Deep Mine Microbial Observatory (DeMMO; Lead, SD) was established in 2015 to provide stable portals

Knocking out ACR2 does not affect arsenic redox status in Arabidopsis thaliana: implications for as detoxification and accumulation in plants.

PLoS ONE, 2012
Many plant species are able to reduce arsenate to arsenite efficiently, which is an important step allowing detoxification of As through either efflux of arsenite or complexation with thiol compounds.

Impacts of Climate Change on Groundwater Quality in the Northern Atlantic Coastal Plain: A Review

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT This review integrates hydrogeological and geochemical processes to assess the impacts of climate change on groundwater quality in the Northern Atlantic Coastal Plain (NACP). Projected changes in air temperature, precipitation, and sea‐level rise are expected to influence groundwater recharge, discharge, storage, and seawater intrusion in ...

RbFe(HAsO4)2 and TlFe(HAsO4)2, two new hydrogenarsenates adopting two closely related structure types

Acta Crystallographica Section E: Crystallographic Communications, 2018
Rubidium iron bis[hydrogen arsenate(V)], RbFe(HAsO4)2, and thallium iron bis[hydrogen arsenate(V)], TlFe(HAsO4)2, were grown under mild hydrothermal conditions (T = 493 K, 7 d). RbFe(HAsO4)2 adopts the RbFe(HPO4)2 structure type (space group R\overline{3}
