Variation in spectral characteristics of dissolved organic matter in inland rivers in various trophic states, and their relationship with phytoplankton

Abstract Dissolved organic matter (DOM) plays an important role in aquatic ecosystems. This study aimed to reveal the variation in spectral characteristics of DOM in inland rivers in various trophic states, and understand the relationship between spectral characteristics of DOM and phytoplankton composition in various trophic states. Our investigation was carried out on the Weihe River in Shaanxi Province, China. Three humic-like substances and one protein-like substance were identified from the DOM by examination of three-dimensional (3D) fluorescence combined with parallel factor (PARAFAC) analysis and UV–Vis spectroscopy. The trophic states in this study area ranged from mesotrophic to hyper-eutrophic (37
