The characteristics of CDOM structural composition and the effect on indirect photodegradation of sulfamerazine

Science of The Total Environment, 2023
Sulfamerazine (SM) is a commonly used antibiotic and have been widely used to control various bacterial infectious diseases. The structural composition of colored dissolved organic matter (CDOM) is known to be a major factor that influences the indirect photodegradation of SM, yet the influence mechanism remains unknown.

New insight into and characterization of DOC, DON and CDOM for urban waters in the lower reaches of the Yellow River, China.

Science of the Total Environment
Dissolved organic matter (DOM), usually measured as concentrations of dissolved organic carbon (DOC) and nitrogen (DON) and chromophoric dissolved organic matter (CDOM), plays a crucial role in the global carbon and nitrogen cycles in inland waters.

Spatiotemporal variations in chromophoric dissolved organic matter (CDOM) in a mixed land-use river: Implications for surface water restoration.

Journal of Environmental Management, 2020
A challenge for current surface water restoration and management in China is acquiring the source information for complex pollution scenarios in order to develop effective control strategies. As an important part of dissolved organic matter, chromophoric

The bio-optical properties of CDOM as descriptor of lake stratification

Journal of Photochemistry and Photobiology B: Biology, 2006
Multivariate statistical techniques are used to demonstrate the fundamental role of CDOM optical properties in the description of water masses during the summer stratification of a deep lake. PC1 was linked with dissolved species and PC2 with suspended particles.

Simple Method to Determine the Apparent Quantum Yield Matrix of CDOM Photobleaching in Natural Waters.

Environmental Science and Technology, 2020
The photobleaching of chromophoric dissolved organic matter (CDOM) is considered an important loss process for CDOM absorption in sunlit natural waters, where it can regulate the biota's exposure to sunlight, surface solar heating, and dissolved organic ...

Absorption coefficient of CDOM in Zhejiang coastal waters

SPIE Proceedings, 2013
Chromophoric dissolved organic matter (CDOM) exists in all natural waters. Researches on optical properties of CDOM play an important role in ocean color remote sensing retrieval. The optical properties of CDOM in Zhejiang coastal waters were investigated from August 18, 2009 to June 9, 2011 covering four seasons.

Colored Dissolved Organic Matter (CDOM) as a tracer of effluent plumes in the coastal ocean

, 2020
Mapping wastewater effluent plumes is typically conducted using ammonia as a tracer, but this provides low spatial resolution since it is collected as discrete bottle samples.

Absorptivity Inversely Proportional to Spectral Slope in CDOM

Environmental Science & Technology
The application of the Bouguer-Lambert-Beer (BLB) Law is limited to dissolved organic matter (DOM) in the environment due to the wide distribution of overlapping chromophores with different molar absorptivities (ε). Here, we report our findings demonstrating the existence of an inverse relationship between ε and the spectral slope (S) in the absorption

CHROMOPHORIC DISSOLVED ORGANIC MATTER (CDOM) IN THE OCEAN: OPTICAL PROPERTIES AND RELATION TO CDOM STRUCTURE AND SOURCE

2014
CDOM is a ubiquitous component of the dissolved organic matter pool which absorbs UV and visible light. Owing to its optical properties it plays a critical role in photochemistry and biogeochemistry in aquatic systems. Extensive data exist on the optical properties of CDOM from both terrestrial and coastal environments, yet the open oceans have been ...
