The biogeochemical cycling of soil organic matter (SOM) plays a central role in regulating
soil health, water quality, carbon storage, and greenhouse gas emissions. Thus, many …

The mesopelagic zone is the oceanic region through which carbon and other elements must
pass in order to reach deeper waters or the sea floor. However, the food web interactions …

Microbes regulate the composition and turnover of organic matter. Here we developed a
framework called Energy-Diversity-Trait integrative Analysis to quantify how dissolved …

Electrospray ionization (ESI) coupled with Fourier transform ion cyclotron resonance mass
spectrometry (FT-ICR MS) has been widely used for molecular characterization of dissolved …

Organic matter decomposition in soils and terrestrial sediments has a prominent role in the
global carbon cycle. Carbon stocks in anoxic environments, such as wetlands and the …

van Krevelen diagrams (O/C vs H/C ratios of elemental formulas) have been widely used in
studies to obtain an estimation of the main compound categories present in environmental …

Ultrahigh resolution mass spectrometry, such as Fourier transform ion cyclotron resonance
mass spectrometry (FT ICR MS), can resolve thousands of molecular ions in complex …

Congo River water was filtered and then irradiated for 57 d in a solar simulator, resulting in
extensive photodegradation of dissolved organic matter (DOM). Whole‐water (ie …

Dissolved organic matter (DOM) is a large and complex mixture of molecules that fuels
microbial metabolism and regulates biogeochemical cycles. Individual DOM molecules have …

Ozonation of drinking and wastewater relies on ozone (O3) and hydroxyl radical (• OH) as
oxidants. Both oxidants react with dissolved organic matter (DOM) and alter its composition …
