Abstract |
|
Particle Size distribution of inhalable aerosols is the most significant factor to estimate the aerosol deposition yield at various respiratory tract. Recently, electronic cigarette (EC), as the alternative of tobacco cigarette, is increasingly popular all over the world. However, emissions from ECs may contribute to both indoor and outdoor air pollution. Also, the number of users is increasing rapidly. In this investigation a mainstream aerosol generated from electronic cigarette were characterized in terms of particle number concentrations and size distributions by using diffusion aerosol spectrometer (DAS). Diffusion aerosol spectrometer is used to determine the ultrafine and fine particles emission in the range from 10-3μm to 10 μm. In this work, aerosol number concentration that injected from the electronic cigarette nearly around40k particles/cm3.Most of these particle concentrations within the ultra-fine particles (UFP) size range (0 to 0.2μm) and the other in the size range from 0.3 to 1 μm. The surface and mass size distributions are calculated and presented. The strength of the electronic cigarette is equal 26x1011(particle/min). |
