Terrestrial humic substances induce photodegradation of polysaccharides in the aquatic environment.
Starch solution (8 mg dm(-3)) was irradiated with simulated solar UV radiation with and without addition of Aldrich humic acids (4 mg dm(-3)). Quantitative analysis of the photodegradation products revealed enhanced release of monosaccharides in the presence of humic substances [corrected].
