Abstract

Excitation-emission matrix spectroscopy (EEMS) combined with parallel factor analysis (PARAFAC) was applied to investigate the fluorescence characteristics and its source of chromophoric dissolved organic matter (CDOM) in the water of Lihu Lake, and the relationship between the fluorescence intensity of different components and other water quality parameter was also discussed. The results indicated that two fluorescence components were identified by PARAFAC, including one tryptophan-like component and one humic-like component, namely C1 (225,280/335) and C2 (250/435). The contribution rates to the total fluorescence intensity of C1 and C2 were 75.70% and 24.30%, respectively. Spatially, fluorescence intensity of C1and C2 decreased from the east district of Lihu Lake to the west, and lakeside areas was higher than lake center. Fluorescence index (FI), the index of recent autochthonous contribution (BIX) and humification index (HIX) show that CDOM in the water mainly derived from microbes, algae and other newly autochthonous sources, appeared weak humic characteristics overall. CDOM was closely related to the transformation and migration of nitrogen and phosophorus, and had important influence on transparency.
