Microplastics play a minor role in tetracycline sorption in the presence of dissolved organic matter.

Environmental Pollution, 2018
Microplastics have a great potential to sorb organic pollutants from the adjacent environment. In this study, the sorption of tetracycline, a polar and ionizable antibiotic, on three types of microplastics (polyethylene (PE), polypropylene (PP) and ...

Alkaline Degradation of Dissolved Organic Matter

Acta hydrochimica et hydrobiologica, 2003
AbstractThe degradation of dissolved organic matter (DOM) was studied in alkaline solution. The products were characterised using UV/vis spectroscopy, size‐exclusion chromatography (SEC), and by the analysis of low‐molecular‐weight organic acids (LMWOA).

Dissolved organic matter characterization of biochars produced from different feedstock materials.

Journal of Environmental Management, 2019
Fluorescence excitation-emission matrix (EEM) spectroscopy coupled with parallel factor analysis (PARAFAC) enables better understanding of the nature of dissolved organic matter (DOM).

Source, structural characteristics and ecological indication of dissolved organic matter extracted from sediments in the primary tributaries of the Dagu River

, 2020
This study aims to analyze the sources, structural characteristics of dissolved organic matter in sediments and potential ecological risk (heavy metal, nitrogen and phosphorus) based on the different characteristics of typical tributaries of the Dagu ...

Succession and diversity of microbial communities in landfills with depths and ages and its association with dissolved organic matter and heavy metals.

Science of the Total Environment, 2019
Landfill is an important method for the treatment of municipal solid wastes. Microbes play a central role in the biodegradation and stabilization of organic matter during landfill; however, the succession of microbial communities in landfills and their ...

Dissolved Organic Matter in Oceanic Waters

Journal of Oceanography, 2003
The amount of information on oceanic dissolved organic matter (DOM) has increased dramatically in the last decade thanks to the advances in chemical characterization. This information has supported the development of some novel and important ideas for DOM dynamics in the ocean.

Relationship between heavy metals and dissolved organic matter released from sediment by bioturbation/bioirrigation.

Journal of Environmental Science, 2019
Organic matter (OM) is an important component of sediment. Bioturbation/bioirrigation can remobilize OM and heavy metals that were previously buried in the sediment.

Sonochemical reactions of dissolved organic matter

Research on Chemical Intermediates, 2004
Property changes of Aldrich and Pahokee peat dissolved organic matter (DOM) at different ultrasonic frequencies and energy densities were systematically investigated. Exposure of DOM to ultrasound resulted in decreases in TOC, Color465, specific UV absorbance (SUVA), aromaticity and molecular weight, while DOM acidity increased.
