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

Fluorescence spectroscopy as a tool for determination of organic matter removal efficiency at water treatment works [PDF]

, 2010
Organic matter (OM) in drinking water treatment is a common impediment responsible for increased coagulant and disinfectant dosages, formation of carcinogenic disinfection-by products, and microbial re-growth in distribution system.

Biodegradability of dissolved organic carbon in permafrost soils and aquatic systems: A meta-analysis [PDF]

, 2015
As Arctic regions warm and frozen soils thaw, the large organic carbon pool stored in permafrost becomes increasingly vulnerable to decomposition or transport.

Exploratory analysis of excitation-emission matrix fluorescence spectra with self-organizing maps as a basis for determination of organic matter removal efficiency at water treatment works [PDF]

, 2009
In the paper, the self-organizing map (SOM) was employed for the exploratory analysis of fluorescence excitation-emission data characterizing organic matter removal efficiency at 16 water treatment works in the UK.

Utilization of ancient permafrost carbon in headwaters of Arctic fluvial networks [PDF]

, 2015
Northern high-latitude rivers are major conduits of carbon from land to coastal seas and the Arctic Ocean. Arctic warming is promoting terrestrial permafrost thaw and shifting hydrologic flowpaths, leading to fluvial mobilization of ancient carbon stores.

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.

Dissolved organic matter transformations in a freshwater rivermouth

Biogeochemistry, 2023
AbstractRiver-to-lake transitional areas are biogeochemically active ecosystems that can alter the amount and composition of dissolved organic matter (DOM) as it moves through the aquatic continuum. However, few studies have directly measured carbon processing and assessed the carbon budget of freshwater rivermouths.

Optical properties and bioavailability of dissolved organic matter along a flow-path continuum from soil pore waters to the Kolyma River mainstem, East Siberia [PDF]

, 2016
The Kolyma River in northeast Siberia is among the six largest Arctic rivers and drains a region underlain by vast deposits of Holocene-aged peat and Pleistocene-aged loess known as yedoma, most of which is currently stored in ice-rich permafrost ...

Virus infection of phytoplankton increases average molar mass and reduces hygroscopicity of aerosolized organic matter

Scientific Reports, 2023
Viral infection of phytoplankton is a pervasive mechanism of cell death and bloom termination, which leads to the production of dissolved and colloidal organic matter that can be aerosolized into the atmosphere.
