Effects of organic sulfur and arsenite/dissolved organic matter ratios on arsenite complexation with dissolved organic matter

Chemosphere, 2022
The speciation and fate of arsenic (As) in soil-water systems is a topic of great interest, in part due to growing awareness of As uptake into rice as an important human exposure pathway to As. Rice paddy and other wetland soils are rich in dissolved organic matter (DOM), leading to As/DOM ratios that are typically lower than those in groundwater ...

Chemodiversity of Soil Dissolved Organic Matter

Environmental Science & Technology, 2020
Dissolved organic matter (DOM) plays a key role in many biogeochemical processes, but the drivers controlling the diversity of chemical composition and properties of DOM molecules (chemodiversity) in soils are poorly understood. It has also been debated whether environmental conditions or intrinsic molecular properties control the accumulation and ...

Cycling downwards – dissolved organic matter in soils

Soil Biology and Biochemistry, 2012
Dissolved organic matter has been recognized as mobile, thus crucial to translocation of metals, pollutants but also of nutrients in soil. We present a conceptual model of the vertical movement of dissolved organic matter with soil water, which deviates from the view of a chromatographic stripping along the flow path. It assumes temporal immobilization

Removal of Dissolved Organic Matter by Anion Exchange: Effect of Dissolved Organic Matter Properties

Environmental Science & Technology, 2008
Ten isolates of aquatic dissolved organic matter (DOM) were evaluated to determine the effect that chemical properties of the DOM, such as charge density, aromaticity, and molecular weight, have on DOM removal by anion exchange. The DOM isolateswere characterized as terrestrial, microbial, or intermediate humic substances or transphilic acids.
