In this study, the effect of the use of heat-not-burn (HnB) products on indoor air quality (IAQ) was evaluated. To do this, the concentrations of nicotine, propylene glycol (PG), and vegetable glycerin (VG) directly emitted when using HnB products were analyzed and compared to those from conventional cigarettes. Furthermore, the levels of VOCs, aldehydes, nanoparticle, and particulate matter (PM) detected when subjects used HnB products in the exposure chamber were evaluated the effect on IAQ. As a result, the range of nicotine levels transferred by HnB products (0.8-1.2 mg cigarette-1) is lower than that by conventional cigarettes (2.4-3.6 mg cigarette-1). On the other hand, the range of VG levels emitted from HnB products (3.1-5.9 mg cigarette-1) were higher than that emitted from conventional cigarettes (0.6-3.0 mg cigarette-1). In addition, although the amount generated from HnB products was small compared to those from conventional cigarettes, various kinds of VOCs, aldehydes, nanoparticle and PM were produced, and these were confirmed to affect IAQ. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Category: alcohols-buliding-blocks).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Category: alcohols-buliding-blocks
