An electronic cigarette, known as an electronic nicotine delivery system or commonly as an e-cigarette, has become a popular alternative to traditional tobacco products since its introduction on the market. It is currently used in many countries around the world and has a wide circle of followers. However, research on the composition of the aerosol inhaled by users of electronic cigarettes is still underway. The results of these studies allow estimating exposure to toxic chemicals. They can become a tool to assess the harmfulness of these devices use. One of the major groups of compounds whose content is determined in the aerosol is carbonyl compounds. They are formed by the partial decomposition of propylene glycol and glycerol (used as base substances) and flavourings at the aerosol generation temperature. Prolonged exposure to carbonyl compounds such as formaldehyde or acetaldehyde is a known factor to increase the risk of asthma and cancer. Hence, precise measurements of these compounds content in the aerosol are important to assess the effect of electronic cigarettes on the users health. This article provides a brief overview of the methods used to determine the carbonyl compounds content in an aerosol generated from electronic cigarettes.
