Characterizing the spatiotemporal distribution of dissolved organic matter (DOM) in the Yongding River Basin: Insights from flow regulation

Yijuan Bai et al.

Summary: Artificial flow regulation is an important measure for improving water shortages and river basin ecological quality. This study investigates the impact of different artificial regulation modes on the source, migration, and transformation of dissolved organic matter (DOM) in rivers. The findings provide insights for developing appropriate management strategies and understanding the effects of artificial flow regulation on carbon cycles and ecological risks in river basins.

The molecular characteristics of dissolved organic matter in urbanized river sediments and their environmental impact under the action of microorganisms

Li Zhang et al.

Summary: This study comprehensively analyzed the characteristics and potential effects of dissolved organic matter (DOM) molecular composition and its relationship with microbial communities in sediments from the Beiyun River, Beijing, China. It found that the dominant substances in the sediments were lignin-like and protein-like substances, with higher content of labile substances increasing the risk of nutrient release. Various microbial communities were found to be closely related to different types of DOM molecules.

Enhanced coagulation for mitigation of disinfection by-product precursors: A review

Pin Wang et al.

Summary: This article introduces the properties of DBP precursors and the control of DBP formation through enhanced coagulation. Metal-based coagulants can reduce the formation of DBP to some extent, while organic polymers and hybrid coagulants have the potential to mitigate DBP formation. In addition, integrated treatment methods are also evaluated for their efficiency in enhancing DBP precursor removal.

Terrestrial dissolved organic matter source affects disinfection by-product formation during water treatment and subsequent toxicity

Hannah M. Franklin et al.

Summary: Restoring riparian zones with woody vegetation can help protect waterways from sediment and nutrient pollution, but leaf litter can lead to dissolved organic matter leaching into surface waters, generating disinfection by-products (DBPs) during water treatment. The study compared the DBPs formed from leachate of two native Australian riparian trees, finding that Eucalyptus tereticornis leachates produced more DBPs and induced greater toxicity in bioassays compared to Casuarina cunninghamiana and reservoir water. Different tree species have unique DBP profiles, with E. tereticornis posing a greater risk to drinking water quality.

Characterization of dissolved organic matter (DOM) in an urbanized watershed using spectroscopic analysis

Lili Lyu et al.

Summary: Urbanization significantly influences DOM concentration and composition, with urban waters containing higher DOM content, CDOM absorption, DOM fluorescence intensity, and a greater proportion of protein-like components compared to non-urban waters. Long-term observations show that impervious artificial surfaces from urban expansion contribute to increased DOM quantity and shift DOM composition towards being more protein-like.

Haloacetic Acids Formation Potential of Tropical Peat Water DOM Fractions and Its Correlation with Spectral Parameters

Muammar Qadafi et al.

Summary: The spectral parameters of DOM fractions in tropical peat water are correlated with the formation of carcinogenic disinfection by-products (DBPs) and haloacetic acids (HAAs), with the hydrophobic acid (HPOA) fraction dominating the DOM composition. UV-Vis absorbance parameters show a strong positive correlation with HAA formation potential (HAA5FP), while A(210)/A(254) and S200-205 parameters are negatively correlated with HAA5FP.

Changing Land Use and Population Density Are Degrading Water Quality in the Lower Mekong Basin

Flavia Tromboni et al.

Summary: This study examined the impacts of land use on water quality constituents in the Lower Mekong Basin, finding that agriculture, urbanization, and population density were linked to decreasing water quality health. Thailand and Laos had higher nitrogen and ammonium concentrations compared to reference conditions, while Cambodia exhibited higher phosphorus values, indicating water quality degradation.
