Quantitative Enhancement of Arsenate Immobilization Induced by Vacancy Defects on Various Exposed Lattice Facets of Hematite.
Environ Sci Technol
January 2025
Geomicrobiology, Department of Geosciences, University of Tübingen, Tübingen 72076, Germany.
Defects are common features in hematite that arise from deviations from the perfect mineral crystal structure. Vacancy defects have been shown to significantly enhance arsenate (As) immobilization by hematite. However, the contributions from vacancy defects on different exposed facets of hematite have not been fully quantified.

Rice physiological straighthead disease is induced by microbially mediated arsenic methylation and usually regionally distributed in paddy soils. However, the biogeochemical mechanism underlying the geographic distribution of microbial communities harboring methylating genes () remains unclear. Herein, we revealed significant ( = 0.

Spot-urinary biomarkers are crucial in medical, epidemiological, and environmental studies, but their variability due to hydration levels requires precise dilution adjustments. Traditional methods, like conventional creatinine correction (CCRC), are limited in compensating for variations in urine concentration, causing substantial inconsistencies, particularly at the extremes of the diuresis spectrum. While restricting the creatinine (CRN) range to 0.

Expert Scientist, Nestle Institute of Health Sciences, Route du Jorat 57, 1000 Lausanne-26, Switzerland.
Background: The Food and Drug Administration's Closer to Zero Action Plan aims to reduce toxic element exposure from foods infants and toddlers eat. Rice has been identified as a source of inorganic arsenic in the diets of infants and toddlers.
Objective: Evaluate consumption of rice and rice-containing foods from the Feeding Infants and Toddlers Study (FITS) 2016.
Health risk assessment of potential heavy metals bioaccumulation in specialty crops grown in farm soils amended with dredged material.
J Environ Manage
January 2025
The Ohio State University, Department of Horticulture and Crop Science, 202 Kottman Hall, 2021 Coffey Rd, Columbus, OH, 43210, USA.
This research examined the potential human health risk associated with heavy metal bioaccumulation in specialty crops (lettuce, tomato, carrot) grown in soils amended with dredged material (DM) from the Toledo Harbor in Ohio, USA. The specialty crops were chosen to expand the scope of the study of dredged material, especially in Northwest Ohio. Previous studies have been focused on corn and soybeans, which are the major crops planted in the area.
