Chromophoric dissolved organic matter(CDOM) is one of the major light absorbing constituents in natural waters,whose optical behavior and biogeochemical cycle play an important role in aquatic ecosystems CDOM light absorption is highest in the ultraviolet(UV) region of the spectrum.CDOM has a broad...
Exudation by aquatic plants and their degradation are also important sources of DOM in natural waters Nagata, 2002, Carlson, 2002. DOM is a heterogeneous mixture of aliphatic and aromatic polymers and its composition varies in time and space depending on proximity to sources and exposure to ...
Photodegradation is another pivotal process for the degradation of biomolecules or contaminants in surface natural waters besides biodegradation(Lee et al., 2014; Lundeen et al., 2014). In addition to direct photodegradation induced by sunlight irradiation, the ubiquitous dissolved organic matter (DOM)...

The isolation, characterization and study of the properties of aquatic dissolved organic matter (DOM) still represent a challenge because of the heterogeneity, complexity and low concentration of organic material in natural waters. Based on its ability to interact with contaminants and thus to modify ...

In all cases, surface seawater fluorescence was low as a result of photochemical bleaching which occurs on the timescale of hours. Fluorescence of deep water was 2–2.5 times higher than that of surface waters, and was constant, implying a long residence time for fluorescent organic matter, ...
