Five polycyclic aromatic hydrocarbonsanthracene, benzo(a)pyrene, pyrene, fluoranthene, and phenanthrenewere adsorbed from the vapor phase onto coal flyash. The susceptibility of each of the adsorbed compounds to photodecomposition was investigated. Benzo(a)pyrene, pyrene, and anthracene all photolyze efficiently in liquid solution but are highly resistant to photodegradation when adsorbed on flyash. Phenanthrene and fluoranthene are resistant to photodecomposition both in liquid solution and as adsorbates on flyash. The environmental consequences of the resistance of PAH's adsorbed on coal flyash to photochemical transformation are discussed. (3 diagrams, 42 references, 3 tables)
