With smoking in buildings as well as in the streetsprohibited, the need for smoking rooms has emerged. In this study, particle and CO contamination in a 63.6 m3smoking room was experimentally investigated using Korean tobacco. Tobacco smoking was artificially simulatedusing a smoking machine. The number and size distribution of particles ranging from 10-420 nm and 0.25-32 μmwere measured using a Nanoscan (TSI model 3910) and a portable aerosol spectrometer (Grimm model 1.109),respectively. CO concentration was also monitored using an IAQ monitor (Graywolf IAQ-Xtra 610). Four tobaccoswere simultaneously smoked in each experiment, and the experiment was repeated four times. Maximum COconcentrations of 7-10 ppm were observed and high concentrations of particles (176,000-1,115,000 particles/cm3for 10-420 nm, 3,700-5,200 particles/cm3 for 0.25-32 μm) were also monitored. The dominant size of tobaccoparticles was about 100 nm in diameter.
