Abstract – Photochemical degradation process for ingredients of sea water (the Caspian Sea) polluted with oil and oil products was investigated under irradiation with the full spectrum of the PRK-4 mercury lamp. The kinetics of changes in total petroleum hydrocarbon level and concentrations of aromatic (BTEX) and aliphatic (n-alkanes) compounds in samples exposed to the action of UV light was studied. It was found that both the total petroleum hydrocarbon level and the level of n-alkanes decreased with an increase in irradiation exposure time. On the contrary, the levels of BTEX aromatic compounds (benzene, toluene, ethylbenzene, xylene) increased with extending exposure periods. The observed UV spectra of the samples were consistent with the established relationships.

 Keywords: sea water, pollution with oil and oil products, UV-radiation, degradation, photochemical transformations.
