The fluorescence of dissolved organic matter in the Mid-Atlantic Bight
Deep Sea Research Part II: Topical Studies in Oceanography, 2002Abstract The fluorescence of dissolved organic matter has been measured on three cruises covering the Mid-Atlantic Bight in the spring of 1994 and 1996 and the summer of 1996. An attempt at a “mass” balance of fluorescent dissolved organic matter (FDOM) on the shelf suggests that more FDOM is present during the spring than during the summer and that ...

The Yangtze Estuary is heavily influenced by coast-continent geochemical processes and anthropogenic activity; thus, the source and distribution of chromophoric dissolved organic matter (CDOM) in the estuary are strongly impacted by these processes. Here, a series of samples were collected from across the Yangtze Estuary to investigate the source and ...

The freshwater dissolved organic matter fluorescence–total organic carbon relationship
Hydrological Processes, 2007AbstractThe fluorescent properties of dissolved organic matter (DOM) enable comparisons of humic‐like (H‐L) and fulvic‐like (F‐L) fluorescence intensities with dissolved organic carbon (DOC) in aquatic systems. The fluorescence‐DOC relationship differed in gradient, i.e.

Summary Recent evidence suggests a key role of bacterioplankton in shaping the composition of the dissolved organic matter (DOM) pool in aquatic systems, not only through consumption but also through production of specific compounds, but the latter process is still not well understood.

Fluorescence quenching effects of antibiotics on the main components of dissolved organic matter
Environmental Science and Pollution Research, 2015Dissolved organic matter (DOM) in wastewater can be characterized using fluorescence excitation-emission matrix and parallel factor (EEM-PARAFAC) analysis. Wastewater from animal farms or pharmaceutical plants usually contains high concentration of antibiotics.

Characterization of dissolved organic matter in the Black Sea by fluorescence spectroscopy
Nature, 1990THE natural fluorescence properties of sea water provide a means of elucidating the complex chemical composition and diverse sources of dissolved organic matter (DOM) in sea water1–6. The positions of excitation and emission maxima for a wide range of natural water samples show remarkable similarity7.

The role of nitrogen in chromophoric and fluorescent dissolved organic matter formation
Marine Chemistry, 2007Abstract Microbial and photochemical processes affect chromophoric dissolved organic matter (CDOM) dynamics in the ocean. Some evidence suggests that dissolved nitrogen plays a role in CDOM formation, although this has received little systematic attention in marine ecosystems.

Fluorescence‐based proxies for lignin in freshwater dissolved organic matter
Journal of Geophysical Research: Biogeosciences, 2009Lignin phenols have proven to be powerful biomarkers in environmental studies; however, the complexity of lignin analysis limits the number of samples and thus spatial and temporal resolution in any given study. In contrast, spectrophotometric characterization of dissolved organic matter (DOM) is rapid, noninvasive, relatively inexpensive, requires ...

Larvaceans and copepods excrete fluorescent dissolved organic matter (FDOM)
Journal of Experimental Marine Biology and Ecology, 2006Chromophoric dissolved organic matter (CDOM) can play an important role in regulating biological production in coastal environments. Fluorescent dissolved organic matter (FDOM) is a subset of the larger CDOM pool that can be used to look at sources of CDOM.
