Effects of Electronic Cigarettes on Indoor Air Quality and Health.

Effects of Electronic Cigarettes on Indoor Air Quality and Health. Annu Rev Public Health. 2020 Jan 07;: Authors: Li L, Lin Y, Xia T, Zhu Y Abstract With the rapid increase in electronic cigarette (e-cig) users worldwide, secondhand exposure to e-cig aerosols has become a serious public health concern. We summarize the evidence on the effects of e-cigs on indoor air quality, chemical compositions of mainstream and secondhand e-cig aerosols, and associated respiratory and cardiovascular effects. The use of e-cigs in indoor environments leads to high levels of fine and ultrafine particles similar to tobacco cigarettes (t-cigs). Concentrations of chemical compounds in e-cig aerosols are generally lower than those in t-cig smoke, but a substantial amount of vaporized propylene glycol, vegetable glycerin, nicotine, and toxic substances, such as aldehydes and heavy metals, have been reported. Exposures to mainstream e-cig aerosols have biologic effects but only limited evidence showing adverse respiratory and cardiovascular effects in humans. Long-term studies are needed to better understand the dosimetry and health effects of exposures to secondhand e-cig aerosols.
