Effect of Dissolved Organic Matter (DOM) on Greenhouse Gas Emissions in Rice Varieties

SSRN Electronic Journal, 2021
Rice paddy fields are importan t sources of atmospheric methane (CH 4 ), and nitrous oxide (N 2 O) . In our previous study, we found that greenhouse gas emissions varied among rice varieties. Dissolved organic matter (DOM) is one of the most reactive organic matter fractions in an ecosystem.

Characterization of dissolved organic matter (DOM) in an urbanized watershed using spectroscopic analysis

Chemosphere, 2021
Landscape urbanization broadly alter watersheds ecosystems, yet the impact of nonpoint source urban inputs on dissolved organic matter (DOM) amount, composition and source is poorly understood. To systematically examine how DOM optical index and composition varied with urbanization, a unique long term observation dataset (4 years) of fluorescence ...

Fate of terrigenous dissolved organic matter (DOM) in estuaries: Aggregation and bioavailability

Ophelia, 2003
Abstract When dissolved organic matter (DOM) from terrestrial and freshwater sources is mixed with estuarine waters at the land-sea interface, the change in salinity has been suggested to cause fast aggregation and an increase in the bioavailability of dissolved organic carbon (DOC) and nitrogen (DON).

Effects of dissolved organic matter (DOM) on the bioconcentration of organic chemicals in aquatic organisms — a review —

Chemosphere, 1998
Current knowledge on the effects of dissolved organic matter (DOM) on the bioconcentration of organic chemicals in aquatic animals (water fleas, mussels, amphipods and fish) is summarized. A graphical representation of the available data gives an overview of the magnitude of the observed effects.

Analysis of adsorption processes of dissolved organic matter (DOM) on ferrihydrite using surrogate organic compounds

Environmental Science and Pollution Research, 2017
Ferrihydrite (Fh) has been recently used in water treatment for removing dissolved organic matter (DOM), but its governing interactions with low-molecular weight DOM are largely unknown. This study aimed to elucidate the influence of chemical structure of DOM on the interactions between functional groups of DOM and Fh using various surrogates ...

[Dissolved organic matter (DOM) dynamics in karst aquifer systems].

Huan jing ke xue= Huanjing kexue, 2015
Dissolved organic matter (DOM) and nutrients have a unique way of producing, decomposing and storing in southwest karst water systems. To understand the biogeochemical cycle of DOM in karst aquifer systems, we investigated the behavioral changes of DOM fluorescence components in Zhaidi karst river system.

Dissolved organic matter (DOM) is independently stratified in thermally stratified water bodies

Journal of Environmental Management
Thermal stratification often occurs in deep-water bodies, including oceans, lakes, and reservoirs. Dissolved organic matter (DOM) plays a critical role in regulating the dynamics of aquatic food webs and water quality in aquatic ecosystems. In the past, thermal stratification boundaries have been sometimes used exclusively to analyze the vertical ...

How representative are dissolved organic matter (DOM) extracts? A comprehensive study of sorbent selectivity for DOM isolation

Water Research, 2017
Solid phase extraction (SPE) has become a widespread method for isolating dissolved organic matter (DOM) of diverse origin such as fresh and marine waters. This study investigated the DOM extraction selectivity of 24 commercially available SPE sorbents under identical conditions (pH = 2, methanol elution) on the example of Suwannee River (SR) water and

Fate of Dissolved Organic Matter (DOM) during Groundwater Recharge Using Reclaimed Wastewater

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
Groundwater recharge using reclaimed wastewater has emerged as an integral part of water and wastewater management in arid regions of the world. This study investigated the fate of dissolved organic matter (DOM) through laboratory-scale soil aquifer treatment (SAT) for a year.
