Size-resolved particulate matter emissions from pine, California oak, east coast oak, eucalyptus, rice straw, cigarette smoke, and meat cooking were analyzed for trace organic species using solvent-extraction followed by GC–MS analysis. Six particle size fractions were studied between 0.056, 0.1, 0.18, 0.32, 0.56, 1.0, and 1.8 μm particle diameter. The smallest particle size fraction analyzed was in the ultrafine (Dp<0.1 μm) range that has been implicated as a potential health concern. Fourteen PAHs were detected in the ultrafine size fraction of wood smoke with the most abundant species (benzo[ghi]fluoranthene) emitted at a rate of 0.2–0.4 (mg kg−1 wood burned). Nine PAHs were detected in the ultrafine size fraction of rice straw smoke with the most abundant compound (benzo[a]pyrene) emitted at 0.01 (mg kg−1 rice straw burned). The most abundant PAH measured in the ultrafine size fraction of cigarette smoke was benzo[ghi]fluoranthene (0.07 mg cigarette−1) followed closely by chrysene/triphenylene (0.06 mg cigarette−1).Besides PAHs, the most abundant compounds identified in the wood included levoglucosan (
