Abstract：Three dimensional excitation-emission fluorescence spectra, chemical oxygen demanding (COD) and dissolved organic carbon (DOC) for water samples from Science Island, Chaohu Lake and Taihu Lake were determined. The COD values of the samples from Chaohu Lake were linearly correlated with the DOC values. Relationships of dissolved organic matter (DOM) concentrations determined by three dimensional excitation-emission fluorescence matrix (3DEEM), observed protein-like fluorescence intensity (Ipro-like) and humic-like fluorescence intensity (Ihum-like) to the chemical oxygen Demanding (COD) for all the samples from different sources were analyzed. Results indicated that DOM concentrations measured by 3DEEM and COD for the water samples from Science Island were well linearly related (r=0.821 72), and the linear relationships also existed between Ipro-like and COD (r=0.846 51), as well as Ihum-like and COD (r=0.836 89). However, for the water samples from Chaohu Lake and Taihu Lake, no linear relationships existed. The cause of the above difference between the water samples from Science Island and those from Chaohu Lake and Taihu Lake, and the feasibility and the limits of the integrated organic pollution measurement using three dimensional excitation-emission fluorescence spectroscopy were further discussed.
