Iron speciation by Mössbauer spectroscopy indicates that ferric iron in an aluminosilicate glass phase is the source of the bioavailable iron in coal fly ash and that this iron species is associated with combustion particles, but not with crustal du

Laboratory methods to produce particle samples from known, reproducible sources with sufficient mass to perform both detailed characterization and replicated in vitro toxicological assays are described. These samples are being used to study the abili

Some recent epidemiologic investigations have shown an association between increased incidence of respiratory symptoms and exposure to low levels of particulate matter (PM*) less than 10 microm or less than 2.5 microm in aerodynamic diameter (PM10 an

The observed iron mobilization rate from size-fractionated coal fly ash is consistent with the model predictions for a limiting case of mass transfer where the dominant resistance is diffusion through a layer of depleted solid between the surface of

Particulate air pollution contains iron, and some of the pathological effects after inhalation may be due to radical species produced by iron-catalyzed reactions. We tested the hypothesis that iron present in coal fly ash (CFA) could induce the expre
