Abstract:
Objective To understand the indoor air pollution caused by smoking and the influencing factors.Methods On the different time after and before smoking,the concentrations of carbon monoxide(CO),inhalabe particle(IP),formaldehyde,total volatile organic compounds(TVOC) in the air in an office were determined,the influence factors such as ventilated conditions and the number of smokers were investigated.Results When the windows and doors were closed,the concentrations of indoor air pollutants at the different time after smoking in the office were obviously higher than those without smoking,and formaldehyde and TVOC still exceeded the standard limit after 3 hours.When the windows and doors were opened,the concentrations of indoor air pollutants after smoking increased obviously,but decreased to the level of no smoking about 30 minutes later.When the windows and doors were opened,the peak values of the indoor air pollutants resulted by smoking were obviously lower than those when the windows and doors were closed.The peak values of the pollutants were positively related to the number of smokers. Conclusion Indoor air pollution caused by smoking is serious.Ventilation can reduce the indoor air pollution effectively.
