ABSTRACT
ABSTRACT: A pilot investigation has been conducted on the influence of several typical daily lifestyles on indoor air quality in terms of environmental PM concentration. The results show that hourly levels of PM 2.5 of dierent sites in the living room revealed obvious dierences due to human activities. However, a good linear regression relationship exists between the indoor and outdoor PM 2.5 values. Besides, smoking in an airtight room rapidly worsened the air quality, making the values of PM greatly exceed the national limit specified by the Air Pollution Index (API). While food was fried or stir-fried in the kitchen, the values of PM 2.5 significantly increased, which may cause a lot of kitchen pollution. Moreover, by the installation of air purifiers, the indoor air quality can be significantly improved.
