Composting of municipal biowaste in the presence of 14C-labelled organic contaminants was studied in an attempt to characterize the mobilization potential of dissolved organic matter (DOM) for hydrophobic contaminants. The properties and transformation of DOM extracted from municipal biowaste compost with 10 mM KCl at six stages during 370 days of ...

Molecular weight fractionation of dissolved organic matter (DOM) released by phytoplankton.
Acta microbiologica Polonica, 1980The application of an ultrafiltration procedure for fractionation of molecular weight of dissolved organic matter (DOM) extracellularly released by phytoplankton is described. Seven ultrafiltration membranes Diaflo (Amicon Corp. USA), with range 500--300,000 molecular weight (MW), were used for separation of different molecular weight compounds ...

Dynamics of dissolved organic matter (DOM) on two salt-affected soils
2010Changes in DOM with time and depth was investigated on two different type salt- affected soils. In 1998 and 2001, from a saline and a sodic sites of grassland, soil samples were taken with five depths (0-90 cm), and measured soil parameters (pH, organic matter, EC, pNa), as well as DOM concentrations.

Background: Engineered carbon nanotubes (CNTs) are expected to be increasingly released into the environment with the rapid increase in their production and use. The discharged CNTs may interact with coexisting contaminants and subsequently change environmental behaviors and ecological effects of both the CNTs themselves and the contaminants. Dissolved

Waste Management, 2009
Dissolved organic matter (DOM) from wastewater rejected by nanofiltration from a landfill leachate treatment plant was fractionated into humic acid (HA), fulvic acid (FA) and hydrophilic (HyI) fractions. It was found that humic substances (HA and FA) composed 75% of the total dissolved organic carbon (DOC) concentration of the DOM, with an average ...

Release and microbial degradation of dissolved organic matter (DOM) and chromophoric dissolved organic matter (CDOM) from the macroalgae Ulva prolifera were studied in laboratory incubation experiments. The release of DOM and CDOM from Ulva prolifera was a rapid process, and hydrolysis played an important role in the initial leaching of the organic ...

Sorption of phenols onto sandy aquifer material: the effect of dissolved organic matter (DOM)
Water Research, 2005The influence of dissolved organic matter (DOM) on the sorption of four phenols, 2,4,6-trichlorophenol (2,4,6-TCP), pentachlorophenol (PCP), 2,4-dinitrophenol (2,4-DNP) and 2-methyl-4,6-dinitrophenol (2-M-4,6-DNP), onto sandy aquifer material at different pH values was investigated using flow through column experiments. The pH-dependent sorption of the

Dissolved organic matter (DOM) and microbial enzymes in the Ross Sea
2018In the Ross Sea the dissolved organic matter and the role of culturable heterotrophic microbes in its degradation are almost unknown. In the carbon cycle, dissolved organic carbon (DOC) concentration and its optically significant fraction, the chromophoric component (CDOM) are important for DOM budget estimates.

Seaweed Gracilaria lemaneiformis, a significant oceanic primary producer, releases substantial dissolved organic matter (DOM) during growth and decay, potentially impacting coastal organic carbon reservoirs and microbial communities. This study aimed to investigate the bioavailability of Gracilaria-derived DOM and its interactions with microbial ...

Dissolved organic matter (DOM) is an important component of solutions in terrestrial and aquatic ecosystems through its influence on acidity, nutrient availability, and toxicity. DOM could enhance the apparent solubility of organic pollutants and alter adsorption-desorption equilibrium of organic pollutants on soil.
