Table 1 Toxicant reduction technologies and target toxicants
From: Approaches for the design of reduced toxicant emission cigarettes
Technology | Cigarette component | Description | Target toxicants |
|---|---|---|---|
Tobacco substitute sheet (TSS) | Blend | Glycerol dilution technology | Whole smoke; additional selectivity volatile phenols |
Blend treated tobacco (BTT) | Blend | Protease treated extracted tobacco | Phenolics and nitrogen-based constituents |
High activity carbon (HAC) | Filter | Polymer-derived (synthetic), spherical carbon beads | Vapour-phase constituents |
Amine functionalised resin | Filter | Amine group functionalised resin (CR20D) | Hydrogen cyanide, volatile acids, and carbonyls |
Triethyl citrate | Filter | Filter tow plasticiser | Volatile phenols |
Split-tipping (ST) | Filter | Ventilation technology; provides an extended ventilation zone | Gases and vapour-phase constituents; reduced overall exposure |
