Dissolved Organic Matter in the Global Ocean: A Primer [PDF]
Gels, 2021 Marine dissolved organic matter (DOM) holds ~660 billion metric tons of carbon, making it one of Earth’s major carbon reservoirs that is exchangeable with the atmosphere on annual to millennial time scales. The global ocean scale dynamics of the pool have become better illuminated over the past few decades, and those are very briefly described here ...

Performance of Alum Coagulation and Adsorption on Removing Organic Matter and E. coli [PDF]
Nature Environment and Pollution Technology, 2023 Surface water is the primary resource for raw water in drinking water treatment processes. Therefore, the presence of microorganisms, bacteria, and viruses should be the main focus in drinking water treatment, in addition to natural organic matter, which

Investigating the Ionization of Dissolved Organic Matter by Electrospray [PDF]
Analytical Chemistry, 2020 Electrospray ionization (ESI) operating in the negative mode coupled to high-resolution mass spectrometry is the most popular technique for the characterization of dissolved organic matter (DOM). The vast molecular heterogeneity and the functional group diversity of this complex mixture prevents the efficient ionization of the organic material by a ...

Chemodiversity of Dissolved Organic Matter in the Amazon Basin [PDF]
Biogeosciences, 2016 Abstract. Regions in the Amazon Basin have been associated with specific biogeochemical processes, but a detailed chemical classification of the abundant and ubiquitous dissolved organic matter (DOM), beyond specific indicator compounds and bulk measurements, has not yet been established.

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
