A multiple linear regression receptor model has been used to apportion ambient concentrations of fine particle extractable organic matter (EOM) and associated mutagenicity (Salmonella typhimurium TA98 +S9), measured in Boise ID during the 1986-1987 winter. Extensive (14)C measurements were also employed to verify the accuracy of the woodsmoke contribution estimate given by the regression approach. In general the Boise results are found to be consistent with those of earlier studies in Albuquerque NM and Raleigh NC, with mutagenic potencies of about 1 and 3 revertants per microgram of EOM for woodsmoke and mobile source emissions, respectively. The measurements were performed as part of the U.S. EPA's Integrated Air Cancer Project.
