Abstract
Abiotic degradation through direct and indirect phototransformation must be assessed to predict the fate of xenobiotics when released into the environment. Experimental procedures must supply data which are intrinsic characteristics of the chemicals examined. A procedure for hydrosoluble compounds which absorbed daylight is essentially based on quantum yield determination. Identification of photoproducts is easier in photoreactions with ionic intermediates than with radicalar photoreactions. A procedure for hydrosoluble compounds, which do not absorb daylight, is proposed which is based on the selection of precise sources for oxygenated reactive species. Examples of indirect phototransformations are given. ZnO-photocatalyzed conversion of dichlorobenzenes and chlorophenols and NO -3 - and NO -2 -photo induced conversion of phenol, nitrophenols and dichlorophenols are presented.
