This report summarizes principal areas of activity and progress in the study of both photochemical and non-photochemical transformation of several PAHs vapor-deposited on a variety of fly ashes as well as more conventional solid surfaces. Future research objectives are also discussed. The general objectives of this research are: (a) to establish the extent to which fly ash surfaces modify the expected photo and thermal reaction chemistry of PAHs and related compounds (both in the absence and presence of other atmospheric pollutants such as O/sub 3/, NO/sub 2/, and SO/sub 2/); (b) to establish correlations (whenever possible) of the behavior described in (a) with the physical and chemical characteristics of fly ash surfaces; (c) to elucidate the fundamental chemical and/or physical phenomena responsible for the perturbing influence of the chemical transformation of PAHs; and (d) to assess the environmental relevance of the influence of fly ash surfaces upon the chemistry of aromatic compounds adsorbed thereon.
