Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

UV Absorption Spectral Characteristics of Dissolved Organic Matter in Fen River of Taiyuan in China

E3S Web of Conferences, 2018
UV absorption is one of the important properties of chromophoric dissolved organic matter (CDOM). The UV absorption spectral characteristics of dissolved organic matter (DOM) were analyzed to infer the main components in Taiyuan urban section.

The ability of dissolved organic matter (DOM) to influence benzo[a]pyrene bioavailability increases with DOM biodegradation

Ecotoxicology and Environmental Safety, 2005
The biodegradation of two substrates and the ability of dissolved organic matter (DOM) to influence benzo[a]pyrene bioavailability as DOM biodegradation progressed were monitored in reactors. Substrates were composed of algae extracts and an artificial substrate that mimics raw wastewater, which were considered to be autochthonous and anthropogenic ...

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Dissolved Organic Matter and Pretreatment Effects on PFAS Removal by Granular Activated Carbon

AWWA Water Science, Volume 8, Issue 3, May/June 2026.
ABSTRACT Granular activated carbon (GAC) adsorption is commonly used to remove per‐ and polyfluoroalkyl substances (PFAS) from water. In this study, we evaluated the impact of dissolved organic matter (DOM) concentration and pretreatment on GAC use rates for PFAS removal.

A storm in a shelf sea: Variation in phosphorus distribution and organic matter stoichiometry [PDF]

, 2014
Organic matter (OM) plays an important role in productive shelf seas and their contribution to global carbon (C) and nutrient cycles. We investigated the impact of storm mixing on OM dynamics in the seasonally stratified Celtic Sea.

Climate and Landscape Controls on Dissolved Organic Matter in Wetland‐Dominated Catchments of the Boreal Plains, Canada

Hydrological Processes, Volume 40, Issue 5, May 2026.
In the subhumid, wetland‐rich, geologically heterogeneous Boreal Plains region of Canada, we found several controls on stream DOC concentration ([DOC]) and DOM composition: An increase in [DOC] and aromaticity as temperature increases throughout the summer, with temperature trend prevailing over the influence of discharge.

Differences in dissolved organic matter and analysis of influencing factors between plantations pure and mixed forest soils in the loess plateau

Frontiers in Forests and Global Change
The dissolved organic matter (DOM) in forest ecosystems significantly impacts soil carbon cycling due to its active turnover characteristics. However, whether different plantation forest soil profiles exhibit distinct DOM characteristics remains unclear.

Universal molecular structures in natural dissolved organic matter

Nature Communications, 2018
Dissolved organic matter (DOM) in aquatic systems is among the most complex molecular mixtures known. Here the authors show that a major component in DOM is molecularly indistinguishable in marine and freshwater environments, which could reflect ...
