Data are presented on the characterization or identification of several higher molecular weight nitro polycyclic aromatic compounds which are major constituents of mutagenically active subfractions in organic extracts of fly ash from conventional pulverized coal combustion (PCC). Compounds found in mutagenically active fractions of PCC fly ash are compared to those found in active fractions of fly ash from an experimental fluidized bed combustion (FBC) unit. Several lines of investigation using both instrumental analysis and selective biological techniques have been used to identify nitro-PAH and oxygenated PAH present in both the FBC and PCC particulates. This paper deals primarily with the chemical characterization of these materials and the instrumental analytical methods used to achieve the reported identifications; the biological techniques used are discussed briefly for completeness.
