The photodegradation of anthracene(AN)and benzo[a]pyrene(BaP),two priority polycyclic aromatic hydrocarbons(PAHs),was examined at ultra-trace levels in surface water to elucidate their behaviour under several irradiance values and types of *** emitting flux and the spectrum of the lamps were found to develop a crucial role in AN and BaP degradation since removal efficiencies of the target contaminants higher than 99%were found after 15 min of irradiation under an ultraviolet c(UVc)irradiance of 0.63 mW/cm^2,corresponding to a fluence of 560.25 mJ/cm^*** the other hand,although ultraviolet A(UVA)lamps exhibited a higher irradiance compared to that of UVc lamps,they were not efficient for degrading the target *** removal kinetic studies corroborated these findings,being the AN elimination rate in surface water higher than that in deionized water at optimal operating *** potential was also measured.A rapid microbial load inactivation,in terms of total coliforms naturally contained in the water matrix studied,was evidenced within 15 min of treatment for the fluence ***,after 24 hr in the dark,a regrowth was ***,photolysis products more toxic than the parent compounds were found,which were not removed even by extending the treatment *** this regard,it can be concluded that the individual action of UVc light for removing AN and BaP with disinfection purposes is not an efficient treatment;therefore,the use of radiation in combination with other kinds of treatments is required.
