Experimental test research on the release characteristics of particulate contaminants in cigarettes

Indoor air quality is particularly important not only in schools, hospitals, nursing homes and other environments that accommodate sensitive people, but also production places with high cleanliness requirements. At present, most researches are aimed at testing the mass concentration of contaminants there few characterizations release characteristics(that is, rate) contaminants. Air pollutants generally include particulate gaseous This paper takes cigarettes as typical representatives solid matters PM2.5 produced by research object. In 30m3 purification test chamber, rate smoldering cigarette smoke generator, diffusion chamber were tested. According to linear regression, fitting curve generator was obtained law static dynamic obtained. The results can provide basic data when pollution sources indoor environment scientific reasonable basis for subsequent on airflow organization, ventilation frequency, cleanliness, etc.
