주택 내 방에서 흡연으로 인한 실내공기질의 변화 Changes in indoor air quality when smoking in a room at home 초록 Smoking is a disservice to not only for smokers who smoke, but also for nonsmokers due to smoke or smell. In particular, smoking harms health by increasing the discomfort associated with the smell generated by burning the cigarette, and giving rise to lung injury or cancer caused by smoke inhalation. The purpose of this study was to investigate the characteristics of various concentrations of nicotine, PM2.5, and heavy metals (As, Cr, Cd, Pb) generated by smoking according to the smoking intensity. When smokers smoked continuously, the amount of nicotine, PM2.5, Cr, and Cd produced by smoking increased proportionally and became statistically significant. However, As and Pb showed a different pattern from other materials, and the concentration increased by 2~3 times when 10 cigarettes were smoked. As for the change in PM2.5 for 12 hours immediately after smoking, about 70% of the particles were deposited on the floor or wall even in a sealed room where no ventilation was available, and the concentration naturally decreased. However, the remaining particles were found to remain in the air even though the time passed exceeded 12 hours.
