Abstract

A method has been developed and validated for the determination of polycyclic aromatic hydrocarbons (PAHs) in the electronic liquid/gas (e-liquid/e-gas) of electronic cigarettes (e-cigarettes) and ignitable/non-ignitable smokeless cigarettes by high-performance liquid chromatography–fluorescence detection. The proposed method was further applied to detect the presence of PAHs in 16 commercially available smoking cessation aids. The analytical method for benz [a]anthracene, chrysene, benzo [b]fluoranthene, benzo [k]fluoranthene, benzo [a]pyrene, dibenz [a,h]anthracene, and benzo [g,h,i]perylene (BghiP) was validated in terms of linearity, limit of detection, limit of quantification, recovery (%), accuracy (%), and precision (%). Results showed low levels of PAHs in all samples, except for the non-ignitable cigarettes. In particular, BghiP was detected in e-liquid even though a mixture of food-grade propylene glycol and vegetable glycerin was used, and at least one PAH was present in the e-gas of all e-cigarettes, except for one. From these results, it is necessary to prepare an accurate quantitative analysis method and investigate unexpected hazardous materials generated from smoking cessation aids to prevent health problems and provide the scientific basis for safety management.
