Detailled emissions of conventional, electronic and heated cigarettes

Abstract

Introduction: Different tobacco products release different compounds; each compound, and each mixture, has different toxicological characteristics. There is a need to systematically record the emissions of the different tobacco products.

Methods: The papers reporting the emissions from conventional, electronic and heated (HTP) cigarettes  published after 2010. The Scopus and Pubmed databases are used using appropriate key words; also the PMI file submitted to FDA for the iQOS notification is used.

Results: Table1 shows the basic bibliometric results of this research.

Table2 shows the number of compounds reported in gas and particulate phase for each type of product.

The gas compounds both in cigs/ecigs are 232, in cigs/HTP 287, in ecigs/HTP 152 and in HTP/PMI 233. The metals both in cigs/ecigs are 57, in HTP/PMI 22, while all found in HTP (34) are dound in cigs and ecigs. The PM compounds in both cigs/HTP are 47 and in HTP/PMI 336.

Conclusions: Cigarettes emit a high number of compounds, while these numbers are quite similar in the case of ecigs and HTPs.
