The principal areas of activity and progress in the work to date are: (1) construction and evaluation of apparatus for preparing fly ash samples upon which controlled quantities of a polycyclic aromatic hydrocarbons (PAH) can be deposited from the vapor phase; (2) detailed examination of techniques for extraction of PAHs and photodecomposition products from fly ash samples following photochemical or non-photochemical reactions; and (3) studies of photochemical and non-photochemical reactivity of various PAH vapor-deposited on various well characterized fly ashes of diverse origin. The conclusion of the extraction study is that 24-hours micro-Soxhlet extraction, using toluene and methanol as extraction solvents, produces highest recoveries and reproducibility of recovery. 16 references, 8 tables.
