Applying Fluorescence Dissolved Organic Matter Spectra and Phytoplankton Biology Index for Assessing Urban River Quality

The relationship between phytoplankton dynamics and dissolved organic matter (DOM) in aquatic systems based on fluorophore properties results poor implementation of methods for water quality monitoring. This study aimed to investigate the relation index estimate by fluorescent components assessment. research was conducted sampling urban river water, followed measuring biological during wet dry seasons. Fluorescence Excitation Emission Matrices (FEEMs) analysis combined with Parallel Factor (PARAFAC) identified three main fluorescence matter, i.e., a fulvic acid-like component (C1) humic (C2 C3), system, whether season or season. C1 mainly generated species, Nitzschia sp., Plectonema Navicula Pinnularia C2 C3 had less significant species. diversity Bacillariophyta stronger contribution release DOM than Cyanobacteria. abundance particular species can be used determine FEEM-derived matter.
