Ocean warming-acidification synergism undermines dissolved organic matter assembly. [PDF]
, 2015 Understanding the influence of synergisms on natural processes is a critical step toward determining the full-extent of anthropogenic stressors. As carbon emissions continue unabated, two major stressors--warming and acidification--threaten marine ...

Relationships between dissolved black carbon and dissolved organic matter in streams [PDF]
Chemosphere, 2021 Black carbon (BC) is a pyrolyzed product derived from incomplete combustion. A major fraction of BC produced by landscape fires is initially deposited onto onsite soils. Atmospheric deposition of soot is known to be an important source of soil BC, especially in watersheds that are not affected by landscape fires. The transport of the dissolved fraction

Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]
, 2011 Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Sorption of dissolved organic matter by freshwater bacterioplankton [PDF]
E3S Web of Conferences, 2021 Here we describe the study of the sorption of high-molecular components of dissolved organic matter (DOM) of natural waters - humic acids - by eight bacterial strains isolated from freshwater.

Mobility of antimony, arsenic and lead at a former mine, Glendinning, Scotland [PDF]
, 2015 Elevated concentrations of antimony (Sb), arsenic (As) and lead (Pb) in upland organic-rich soils have resulted from past Sb mining activities at Glendinning, southern Scotland. Transfer of these elements into soil porewaters was linked to the production

Organic carbon transport and C/N ratio variations in a large tropical river: Godavari as a case study, India [PDF]
, 2005 This study gives an insight into the source of organic carbon and nitrogen in the Godavari river and its tributaries, the yield of organic carbon from the catchment, seasonal variability in their concentration and the ultimate flux of organic and ...
