Journal ArticleDOI
Dehalogenation of polybrominated diphenyl ethers and polychlorinated biphenyl by bimetallic, impregnated, and nanoscale zerovalent iron.
Yuan Zhuang,Sungwoo Ahn,Angelia L. Seyfferth,Yoko Masue-Slowey,Scott Fendorf,Richard G. Luthy +5 more
TL;DR: The XPS and chemical data suggest about 7% of the total iron within the activated carbon was zerovalent, which shows the difficulty with in-situ synthesis of a significant fraction of zerVelent iron in the microporous material.
Journal ArticleDOI
Silicate Mineral Impacts on the Uptake and Storage of Arsenic and Plant Nutrients in Rice (Oryza sativa L.)
TL;DR: The relationship between total grain- and straw-As was negatively correlated with pore-water Si, and the relationship differed between two soils exhibiting different mineralogy, illustrating the importance of Si mineralogy on arsenic uptake.
Journal ArticleDOI
Arsenic localization, speciation, and co-occurrence with iron on rice (Oryza sativa L.) roots having variable Fe coatings.
TL;DR: The investigation shows that variable Fe plaque formation affects As entry into rice roots with variable Fe coatings, and shows that Fe plaque serves as a bulk scavenger of As predominantly near the root base.
Journal ArticleDOI
Soil Incorporation of Silica-Rich Rice Husk Decreases Inorganic Arsenic in Rice Grain
Angelia L. Seyfferth,Andrew H. Morris,Rattandeep Gill,Kelli A. Kearns,Jessica N. Mann,Michelle Paukett,Corey Leskanic +6 more
TL;DR: This proof-of-concept study shows that rice husk incorporation to soil decreases inorganic grain As by 25-50% without negatively affecting grain Cd, yield, or dissolved CH4 levels.
Journal ArticleDOI
Arsenic concentrations in paddy soil and rice and health implications for major rice-growing regions of Cambodia.
TL;DR: Overall, soil-extractable concentrations of As, Fe, P, and Si and total As were poor predictors of grain As concentrations, while biogeochemical factors leading to reduction of As(V)-bearing Fe(III) oxides are likely most important for predicting plant-available As.
