Schematic diagram of production of TPM/ACM and aerosol AqE from 3R4F (Ai) and ePen (Bi) aerosol emissions. AqE was prepared by capturing water‐soluble vapor and particulate aerosol constituents in cell culture medium using a glass impinger (Aii and Bii). TPM/ACM was generated by trapping aerosol matter on a Cambridge filter pad and then eluting this using DMSO (Aiii and Biii).
