VOC and Metal Biomarkers Found in E-cigarette Users
Hiler M, Weidner A, Hull LC, et al. Systemic biomarkers of exposure associated with ENDS use: a scoping review. Tobacco Control 2023;32:480-488. “This scoping review provides an overview of the existing literature on biomarkers of exposure from electronic nicotine delivery systems (ENDS) use and identifies gaps in existing knowledge.
Consistent, although limited, evidence shows that exclusive ENDS users have elevated levels of biomarkers of certain volatile organic compounds (VOCs; eg, acrylamide and acrylonitrile), metals (eg, cadmium and selenium), and propylene glycol compared with non-users; however, evidence for biomarkers of other toxicants (eg, acrolein, benzene, and chromium) is mixed… Additional rigorous, controlled studies can assess biomarker exposures from ENDS use and inform the overall risk–benefit of ENDS use for different user populations.”
