Abstract
Humic substances in aqueous solution undergo characteristic alterations when irradiated with light of wavelengths >290 nm. Humic substances subjected to a preliminary irradiation are less capable of generating reactive oxygen species; this indicates a decrease in photoreactivity. This effect is accompanied by changes in spectroscopic (UV, ESR) and other physical properties of the samples.
