An ambient air sampling program was conducted in a wood smoke impacted residential area of Junea, Alaska during the winter of 1985-86. The study was undertaken to determine the bacterial mutagenicity (Ames test) and chemical characteristics of respirable particulate matter collected in the area. Fine particle concentrations for the sampling period of November 16th to January 7th ranged from 1.19 to 209.8 micrograms per cu. m. Bioassay samples from ambient air fine particle concentration periods of 25.6 to 209.8 micrograms per cu. m. showed indirect acting mutagenicities of 6.64 to 77.8 rev./cu. m. with a mutagenicity/particle concentration correlation coefficient of 0.89. The indirect acting mutagenic potency values ranged from 0.29 to 1.44 rev/micrograms of extracted organics and averaged 0.73 +/- 0.26.
