Figure 3.4. EEMs for sample showing humic-like C, with peaks C and A
C
(above) and for a sample
showing humic-like M component, with peaks M and A
M
(bottom). Note that both peaks in the bot-
tom panel are blue-shifted relative to the peaks in the top panel.
A
M
. Taken together, these two peaks comprise humic-like component M. Peak A
M
displays
variability in peak position in parallel to peak M, such that excitation and emission max-
ima for both type M humic-like peaks are blue-shifted relative to the analogous maxima for
type C humic-like fluorescence (

).
