RU indicates the Raman Unit (nm-1) calibration of luorescence intensity of the samples studied whereas excitation and emission wavelength is much differed from standard quinine sulfate
unit (QSU) calibration (Mostofa et al. 2005b )
Peak M p means luorescence Ex/Em maxima of fulvic acid which is photobleached by photochemical processes or by any other natural processes
Peak M indicates the allochthonous and autochthonous fulvic acid (M-like)
a Indicates river EEM data is deducted from sample before PARAFAC modeling on the matrix data
b Ranges expresses the authentic standard at various concentrations (1-5 mg L 1 ) and mechanical reproducibility
c Indicates that the components are identiied using the PARAFAC model on the original EEM of that published paper
Peak′ means the peak is at this region, but not speciied in the paper; UD unpublished data
