摘要

An aerosol study was carried out in a test room measuring particulate matter (PM) with an aerodynamic diameter smaller than 10, 4, 2.5 and 1 μm (PM 10 , PM 4 , PM 2.5 , PM 1 ) before and during the use of electronic alternatives to tobacco cigarettes (EATC) IQOS ? , GLO ? , JUUL ? , with different kinds of sticks/pods, as well as during the smoking of a conventional tobacco cigarette. The aerosol was mainly in the PM 1 size range (95%). All studied EATCs caused lower indoor PM 1 concentrations than conventional tobacco cigarettes. Nevertheless, they determined a worsening of indoor-PM 1 concentration that ranged from very mild for JUUL ? —depending on the pod used—to considerably severe for IQOS ? and GLO ? . Median values ranged from 11.00 (Iqos3 and Juul2) to 337.5 μg m ?3 (Iqos4). The high variability of particle loadings was attributed both to the type of stick/pod used and to the different way of smoking of volunteers who smoked/vaped during the experiments. Moreover, during vaping IQOS ? and GLO ? indoor PM 1 concentrations reach levels by far higher than outdoor concentrations that range from 14 to 21 μg m ?3 , especially during the exhalation of the smoke. From these results emerge an urgent need of a legislative regulation limiting the use of such devices in public places.
