Introduction: Although numerous studies have estimated the inhalation dose of metals emitted from electronic cigarettes (e-cigs), the impact of factors including aerosol size and the atomising power of e-cig aerosols on estimating the inhalation dose of metals remains underexplored. A comprehensive understanding of these determinants is essential to assess the health risks associated with inhaling e-cig aerosols, which may contain potentially harmful metals.
Objectives: The aim of this study is to elucidate the mass and inhalation doses of potentially harmful metals in e-cig aerosols by different particle size and their association with the various atomising powers of e-cig devices and flavours.

Electronic cigarettes (e-cigs) have increased in popularity and usage over the last few decades. There is rising concern regarding the long-term effects of e-cigs on human health, considering their relatively recent introduction to the market. E-cigs are generally composed of a liquid containing nicotine and various chemicals, a battery, a vaporization chamber, and a coil that serves to heat the liquid upon inhalation of the mouthpiece.

A robust analytical method was developed for the determination of per- and polyfluoroalkyl substances (PFAS) in e-cigarette refill liquids using solid-phase extraction (SPE) with weak anion-exchange sorbent, followed by detection with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The design of experiment approach was employed to optimize sample preparation, leading to the validation of the method with limits of detection for PFAS ranging from 0.24 to 1.
