IAQ Applications: The Hazards of E-Cigarettes PDF

This column talks about the results of a study that concluded that e-cigarettes emit harmful chemicals into the air and need to be regulated in the same manner as tobacco smoking. It says there is evidence that nitrosamines, a group of carcinogens found specifically in tobacco, are carried over into the e-cigarette fluid from the nicotine extraction process. And, there is evidence that the glycol carriers can by oxidized by the heating elements used in e-cigarettes to vaporize the liquids, creating aldehydes such as formaldehyde.
