Abstract

Results of studies on chemical and photochemical transformations of polycyclic aromatic hydrocarbons (PAH) are reviewed. Various parameters may modify the kinetics of these reactions, such as light intensity, concentration of gaseous pollutants (NOx, SOx, O3), chemico-physical characteristics of particulates or substrates into which the PAH are adsorbed. Depending on these variables, the half-life of BaP varies from 10 to 104 300 min. The possibility of artefact formation during sampling is discussed. The necessity of clarifying mechanisms for these phenomena, in order to correctly evaluate the risks for exposed populations, is emphasized.
