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.

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.

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.

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 ...

Comparison of optical properties of chromophoric dissolved organic matter (CDOM) in alpine lakes above or below the tree line: insights into sources of CDOM

Photochemical & Photobiological Sciences, 2015
Here we investigated absorption and fluorescence properties of chromophoric dissolved organic matter (CDOM) in 15 alpine lakes located below or above the tree line to determine its source and composition. The results indicate that the concentrations of CDOM in below-tree-line lakes are significantly higher than in above-tree-line lakes, as evidenced ...

A Chromophoric Dissolved Organic Matter (CDOM) Observatory

2010
Abstract : The long-term goal of this project is to develop an understanding of coastal systems such that optical properties of complex coastal waters can be retrieved and predicted from remote sensing and modeling efforts. This project focuses on establishing a moderate-scale observatory to develop watershed and coastal ocean models and remote sensing

Optical Properties of Humic Substances and CDOM: Effects of Borohydride Reduction

Environmental Science & Technology, 2010
Treatment of Suwanee River humic (SRHA) and fulvic (SRFA) acids, a commercial lignin (LAC), and a series of solid phase extracts (C18) from the Middle Atlantic Bight (MAB extracts) with sodium borohydride (NaBH(4)), a selective reductant of carbonyl-containing compounds including quinones and aromatic ketones, produces a preferential loss of visible ...

Importance of CDOM Distribution and Photoreactivity in a Shallow Texas Estuary

Estuaries and Coasts, 2009
This study examined freshwater discharge of dissolved organic matter (DOM) to the shallow Lavaca–Matagorda (LM) Bay estuarine system along the central Texas coast and investigated whether chromophoric DOM (CDOM) photochemical reactions have the potential to stimulate microbial activity within LM estuarine waters.
