Photochemical Reactions of Particle-Associated PAHs

The reviews Toxicological Indications of the Organic Fraction of Aerosols A Chemist s View by Van Cauwenberghe and Van Vaeck (1983) and Atmospheric Reactions of PAH by Van Cauwenberghe (1985) provide critical assessments and extensive literature references of the status of research to 1985 in the complex area of heterogeneous photochemical reactions and of the interactions of PAHs on laboratory substrates, primary combustion particles, and ambient particulate matter with ozone and NOz in air. In the following sections, we briefly summarize results from this earlier era and address subsequent studies on heterogeneous atmospheric reactions of PAHs in simulated and real atmospheres. 

These photochemical reactions in liquids and on solid surfaces are discussed in the following sections.
