Carbonyls emissions in different brands and flavours of heated tobacco products

Heated tobacco products have been launched in a variety of brands and flavours; however, published data covering carbonyl emissions not cover all the different brands and flavours. This work focuses on the carbonyls emissions from 5 heated tobacco products (HTPs) brands: IQOS, LIL, PULZE, ILUMA and GLO and 3 different flavours per brand (IQOS and ILUMA:Yellow Selection-Silver Selection-Turquoise Selection, LIL: Regular-Marine-Roxo, PULZE: Rich Bronze-Ice-Capsule Polar and GLO: Classic Tobacco-Arctic Click-Scarlet Click), under ISO and Health Canada Intense (HCI/CAN) puffing regimes. The carbonyls are collected in an acidified DNPH solution and analyzed by HPLC-UV. Seven carbonyls were detected: Formaldehyde, Acetaldehyde, Propionaldehyde, Butyraldehyde and Crotonaldehyde and Acrolein/Acetone together. The results (Fig 1, Fig 2) show that the HCI/CAN puffing regime leads in general to an increase in carbonyls emissions. Acetaldehyde is the dominant carbonyl, followed by Propionaldehyde, Butyraldehyde, Formaldehyde and Crotonadehyde. The impact of the brand is more significant comparing to the flavour. Fig 1.
