Direct injection- thermal desorption- gas chromatograph/mass spectrometry (DTD/GC/MS) is applied to fine particulate matter (PM) in environmental tobacco smoke (ETS) . In this method, PM collected on quartz fiber filter is directly put into an injector of GC, and desorbed organic gas is analyzed by GC/MS. Nicotine and 12 kinds of PAHs in PM of μg-level are determined within 30 minutes without any pretreatment. The determination limits for nicotine and BaP were 25 pg and 150 pg, respectively. Ultrafine particles in ETS of smoking and non-smoking area were analyzed. Nicotine and PAHs of low vapor pressure should be a marker of tobacco smoke. Carcinogenic Dibenzo (a, h) anthracene was detected only in the smoking area. Ultrafine particles in simulated ETS were also analyzed. Time course of each chemical in different size PM was obtained.
