Passive Exposure to Pollutants from a New Generation of Cigarettes in Real Life Scenarios.

The use of electronic cigarettes (e-cigarettes) and heat-not-burn tobacco (HNBT), as popular nicotine delivery systems (NDS), has increased among adult demographics. This study aims to assess the effects on indoor air quality of traditional tobacco cigarettes (TCs) and new smoking alternatives, to determine the differences between their potential impacts on human health. Measurements of particulate matter (PM, PM and PM), black carbon, carbon monoxide (CO) and carbon dioxide (CO) were performed in two real life scenarios, in the home and in the car.
