Building on more than 30 years of air quality research in some of the most polluted urban environments on Earth, a team of atmospheric scientists at the Desert Research Institute (DRI) have turned their attention toward the growing e-cigarette industry and the unidentified effects of vaping on human health. googletag.cmd.push(function() { googletag.display(‘div-gpt-ad-1449240174198-2′); }); New research published this week in Environmental Science & Technology, a journal of the American Chemical Society, reports that the aerosols (commonly called vapors) produced by flavored e-cigarettes liquids contain dangerous levels of hazardous chemicals known to cause cancer in humans. The study “Flavoring compounds dominate toxic aldehyde production during e-cigarette vaping” confirms that these toxic aldehydes, such as formaldehyde, are formed not by evaporation, but rather during the chemical breakdown of the flavored e-liquid during the rapid heating process (pyrolysis) that occurs inside e-cigarettes or electronic nicotine delivery systems (ENDS). “How these flavoring compounds in e-cigarette liquids affect the chemical composition and toxicity of th...
