The Utilization of Dissolved Organic Matter Spectral and Molecular Properties in Freshwater Eutrophication Studies: A Mini Review

Water, Год журнала: 2025, Номер 17(2), С. 151 - 151

Опубликована: Янв. 8, 2025

Eutrophication is a major environmental issue affecting freshwater ecosystems worldwide. While its impact on the composition of dissolved organic matter (DOM) well recognized, relationships between DOM’s optical and molecular properties across eutrophication gradients remain underexplored. This review synthesizes recent research (derived from UV-Vis absorption fluorescence spectroscopy) characteristics (analyzed using Fourier-transform ion cyclotron resonance mass spectrometry, FT-ICR MS) in systems varying trophic states. Generalized additive model (GAM) analysis was used to assess correlations state index (TSI). The carbon (DOC), a254, SUVA254, SR, HIX, BIX, FI averaged 11.44 ± 11.97 mg/L, 23.23 16.95 m−1. 2.98 0.99 L·mg−1·m−1, 1.42 0.38, 2.38 1.31, 1.08 0.16, 2.11 0.44, respectively, mesotrophic middle-eutrophic sites. GAM results revealed significant linear correlation DOC properties, including FI, with TSI, suggesting that DOM accumulation intensifies eutrophication. such as O/C H/C ratios, double bond equivalents (DBEs), CHOS% content, exhibited nonlinear TSI. These trends imply shift sources terrestrial macrophyte-derived inputs those dominated by algal- sediment-derived progresses. We concluded indices alone may not serve reliable indicator states; future studies should focus integrating both offer more comprehensive assessment Given limited number variables examined this study, work only offers preliminary investigation into relationship changes More systematic focusing molecular-level analyses states broader geographic scale are needed.

(1) They raised a question about seasonal variation dissolved carbon dioxide concentration (cCO2) flux (FCO2) found study over dry season wet season. main point that studies they cited (two river one lake conducted lower Ganges-Brahmaputra) showed higher cCO2 FCO2 during season, while variable seasons at three sites central China. In comments, however, several important differences between were ignored, which need be pointed out clarified.First, aimed determine effect diel fluctuations FCO2, not only difference absolute values. To achieve this, we used ratio day-to-night as an indicator. Our data decreased from cool–dry (0.79) warm–wet (0.25), indicating strong dynamics carbon.Second, climate conditions area (central China) (the are drastically different. Temperatures China significantly than those Ganges-Brahmaputra, amount precipitation temperature level monsoon tropical Ganges-Brahmaputra can greatly strengthen terrestrial aquatic cycling, compared with northern subtropical While acknowledge seasonality different water bodies (e.g., lakes, reservoirs, ponds) (2−8) impacted rainfall associated nutrient inputs, findings lentic system hardly Ganges River has discharge fluctuation hundred cubic meters per second >40 000 m3/s Seasonality such large rivers been evidenced number studies.
