Dilute mixtures of wood combustion emissions (with and without additional NOx) were irradiated in a 22.7-m3 Teflon smog chamber. The effluent was tested for mutagenic activity by exposing Salmonella typhimurium, strains TA100 and TA98, to the filtered gas-phase components. The particulate matter was tested by using the plate incorporation procedure. Without added NOx, irradiated dilute wood smoke showed a measurable increase in mutagenic activity for gas-phase products only. Additional NOx was added in other irradiations to enhance the formation of gas- and particulate-phase products. (Copyright (c) 1986 American Chemical Society.)
