“In this paper, an experimental campaign was carried out in order to measure the characteristics of electronic cigarettes aerosol and evaluate its carcinogenic effects on active and passive vapers. To this end, aerosol particle number and surface area concentrations were measured by means of a condensation particle counter (CPC 3775, TSI Inc.) and a fast mobility particle sizer

(FMPS 3091, TSI Inc.) for mainstream and second-hand aerosol, while data of particle mass (PM10) and toxic compounds (IARC Group 1 carcinogenic) deposited on particle surface were assessed through an extensive literature analysis.”
“The extra risk of developing lung cancer due to the mainstream electronic cigarette (EC) aerosol exposure is lower than the limit values proposed by EPA and WHO, leading to the conclusion that electronic cigarettes are safer than traditional cigarettes, under the conditions described in this paper.” However, “higher risks are associated to ECs with nicotine due to the presence of NNN and NNK. In particular, NNK, As and Cd are the main contributors to the total excess lifetime cancer risk (ELCR) for ECs with nicotine, while for ECs without nicotine, the main contributor is Cd.”
