Combustion of coal for electric power generation has increased markedly throughout the past decade and is expected to continue to increase throughout the remainder of this century. Coal combustion produces a variety of biologically active inorganic and organic compounds. Of major concern is the release of oxides of carbon, nitrogen, and sulfur; biologically active trace elements; siliceous primary particulate matter; and organic compounds. Most of the primary particulate matter produced during coal combustion is coal fly ash. Interaction of fly ash particles with inorganic and organic compounds formed during the combustion process produces a unique complex mixture. This mixture may serve as a model for other mixtures resulting from interaction of relatively inert carrier particles with biologically active metals and organic compounds; the bulk of atmospheric particulate matter may serve as a matrix for subsequent interaction of airborne vapors and condensable gases. In this report, we review our studies that indicate the complexity of the physical and chemical properties of coal fly ash and attempt to relate such properties to the biological activity of coal fly ash.
