This paper summarizes experimental results of a study of natural dissolved organic matter (DOM) fluorescence spectra excited with a UV radiation from a cw lamp source and a pulsed laser. The spectral changes caused by UV light depend on the dose of radiation and on its spectrum as well as on a water sample composition. The difference in UV lamp and laser source action on DOM is under consideration in this paper. A model of photochemical processes in DOM is proposed.
