Investigating the biogeochemistry of dissolved organic matter (DOM) requires the synthesis
of data from several complementary analytical techniques. The traditional approach to data …

Carbon-derived dissolved organic matter (CDOM) are inevitably released to surface water
during returning agricultural biomass carbon to farmland, which are potential precursors of …

Sediment organic matter (SOM) was extracted in an alkaline solution from 43 stream
sediments in order to explore the anthropogenic signatures. The SOM spectroscopic …

Dissolved organic matter (DOM) helps regulate aquatic ecosystem structure and function. In
small streams, DOM concentrations are controlled by transport of terrestrial materials to …

Dissolved organic matter (DOM) chemistry in rivers regulates aquatic food web dynamics,
water quality, and carbon storage. The operation of reservoirs represents one of the major …

The molecular composition and origin has recently been demonstrated to play a critical role
in the persistence of organic matter in lake water, but it is unclear to what degree chemical …

Multiple sources contribute to the presence of antibiotic residues in water environments, and
the environmental risks caused by antibiotics were paid more and more attention. This work …

Global warming can substantially affect the export of dissolved organic carbon (DOC) from
peat-permafrost to aquatic systems. The direct degradability of such peat-derived DOC …

Organic nitrogen (ON) is an important participant in the Earth's N cycle. Previous studies
have shown that penguin feces add an abundance of nutrients including N to the soil …

Photochemical processing is an important way to transform terrestrial dissolved organic
matter (DOM) but was rarely investigated by ultra-high resolution mass spectrometry. We …
