Abstract Samples were obtained from selected positions in the process stream of an experimental low Btu gasifier using a five-stage multicyclone train and a four-stage condenser train. These materials which represent potential fugitive emissions were screened for mutagenic activity (AmesSalmonella mammalian microsome mutagenicity assay) and forin vitro cytotoxicity (alveolar macrophages). Size-fractionated materials collected in the multicyclone train were mutagenic inSalmonella tester strains TA-98 and TA-100 and were also cytotoxic. There appeared to be no relationship between aerosol droplet size and mutagenic activity. Studies with condenser train samples indicate that neutral and basic polynuclear aromatic compounds contribute to the mutagenicity of process stream materials. Specific mutagenic and cytotoxic activity of material was reduced as gas underwent cleanup. A reduction in the mass loading of potentially toxic compounds is achieved by the control devices in the process stream of the experimental gasifier being developed and tested by METC, and assuming equal probability of emissions throughout the process stream, risk from exposure to potential fugitive emissions is reduced as the gas is cleaned.
