Abstract:Aerosol particle formation and growth has been observed in aging, initially particle-free gases obtained from ltered mainstream cigarette smoke. The time scale of particle formation and growth was on the order of minutes and was highly dependent on cigarette tobacco type. Measurements by both ensemble and single particle light-scattering methods were consistent with scattering from an aerosol with a xed number of particles that grow into the tenth micron range. The rate of particle size increase agreed best wi… Show more
