We believe that the minimal CDOM fluorescence quantum yield observed at [[lambda].sub.ex]~270-280 nm could be partially resulting from absorption of light by chromophoric groups similar to aromatic amino acids, short peptides, or proteins and thus leading to reduction in humic-like fluorescence excited at this wavelength range.
