Relating dissolved organic matter fluorescence and functional properties
Chemosphere, 2008The fluorescence excitation-emission matrix properties of 25 dissolved organic matter samples from three rivers and one lake are analysed. All sites are sampled in duplicate, and the 25 samples include ten taken from the lake site, and nine from one of the rivers, to cover variations in dissolved organic matter composition due to season and river flow.

Fluorescence Approach for the Determination of Fluorescent Dissolved Organic Matter
Analytical Chemistry, 2017Excitation-emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor (PARAFAC) analysis has been widely applied to characterize dissolved organic matter (DOM) in aquatic and terrestrial systems. However, its application in environmental samples is limited because PARAFAC is not able to handle nontrilinear EEM data, leading to the ...

Biological lability of streamwater fluorescent dissolved organic matter
Limnology and Oceanography, 2012We investigated the biological lability of fluorescent dissolved organic matter (FDOM) from a temperate Piedmont stream. Plug‐flow bioreactors, colonized and maintained with natural stream water, were used to determine the concentrations of stream‐water biodegradable dissolved organic carbon (BDOC) and relative concentrations of FDOM within ...

The fluorescence of dissolved organic matter in seawater
Marine Chemistry, 1992A total of 28 vertical profiles of seawater fluorescence was measured in the Sargasso Sea, the Straits of Florida, the Southern California Borderlands, and the central Pacific Ocean. In all cases, surface seawater fluorescence was low as a result of photochemical bleaching which occurs on the timescale of hours.

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.

Fluorescent Dissolved Organic Matter in Natural Waters
2012Dissolved organic matter (DOM), of allochthonous and autochthonous origin, is a heterogeneous mixture of organic compounds, with molecular weights ranging from less than 100 to over 300,000 Da in natural waters. The DOM components are involved into key biogeochemical processes such as global carbon cycle, nutrient dynamics, photosynthesis, biological ...

Thermal fluorescence quenching properties of dissolved organic matter
Water Research, 2005The fluorescence excitation-emission matrices of dissolved organic matter (DOM) are investigated between 10 and 45 degrees C for river and waste waters and organic matter standards. With increased temperature, fluorescence intensity is quenched. It is demonstrated that for a range of river and wastewater samples, that tryptophan-like fluorescence ...

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.

Fluorescent dissolved organic matter in marine sediment pore waters
Marine Chemistry, 2004Abstract Fluorescent dissolved organic matter (FDOM) in sediment pore waters from contrasting sites in the Chesapeake Bay and along the mid-Atlantic shelf/slope break was studied using three-dimensional fluorescence spectroscopy. Benthic fluxes of FDOM were also examined at the Chesapeake Bay sites. The major fluorescence peaks observed in these pore

Environmental Science & Technology, 2010
The fluorescent properties of dissolved organic matter (DOM) are often studied in order to infer DOM characteristics in aquatic environments, including source, quantity, composition, and behavior. While a potentially powerful technique, a single widely implemented standard method for correcting and presenting fluorescence measurements is lacking ...
