Coal fly ash samples from an experimental fluidised-bed combustor were evaluated for cytotoxicity and for mutagenicity. The samples were collected by cyclones, a fabric filter and an electrostatic precipitator, at various temperatures. Sample collection parameters that may affect the cytotoxicity and mutagenicity of fly ash were examined. The cyclone samples, collected at higher temperatures, contained larger particles and exhibited little cytotoxicity or mutagenicity, in contrast to the fabric filter and electrostatic precipitator samples, which were collected downstream of the cyclones and at lower temperature, and contained finer particles. The electrostatic precipitator sample was the most mutagenic of the samples investigated.
