Does this indicate that a protein-like, low molecular weight DOC can also be highly photo-degradable if it has not yet been exposed to sunlight? The marginally significant positive correlation (p = 0.07) between the BR-DOC and PD-E w might suggest that the pools of DOC that support bio- and photo-degradation could be the same ( Fig. 2g ), as further supported by the positive correlation between a254/a365 and PD-E w (p < 0.0001) ( Fig. 2f ).
