Two respirable coal fly-ash samples (3 micrometers) were evaluated for physical properties chemical composition, and biological activity, including cytotoxicity and mutagenicity. These two fly-ash samples were collected from a pressurized fluidized-bed combustion miniplant and from a conventional-combustion power plant, both burning eastern coal. All samples collected by a fabric filter downstream of the plant particulate control devices at 165 C (for fluidized-bed combustion fly ash) or 130 C (for conventional combustion fly ash). The two coal fly-ash samples were found to have different properties.
