However, Denver International Airport, the state’s only remaining exempted public workplace, continues to expose workers and travelers who patronize designated “smoking lounges” – exclusively contracted bar and restaurant establishments – to the health risks posed by secondhand tobacco smoke.
Denver’s old Stapleton International Airport was set to go smoke-free per the original version of Executive Order 99 issued by former Mayor Federico Pena in 1990. DIA was to be smoke-free as well. However, Executive Order 99 was stayed, and eventually amended in 1993, enabling construction of two “smoking lounge” concessions (now four) at DIA.
The Health Risks of Secondhand Tobacco Smoke
The 2006 Surgeon General’s Report on The Health Consequences of Involuntary Exposure to Tobacco Smoke confirmed the known health effects of secondhand smoke exposure, including immediate adverse effects on the cardiovascular system, and coronary heart disease and lung cancer. The report concluded that there is no safe level of exposure to secondhand smoke and that establishing smokefree environments is the only proven way to prevent exposure. The report also finds that many millions of Americans are still exposed to secondhand smoke despite substantial progress in tobacco control.
What’s Contained in Secondhand Tobacco Smoke?
According to the Centers for Disease Control, tobacco smoke is a complex mixture of gases and particles that includes smoke from the burning cigarette, cigar, or pipe tip (sidestream smoke) and exhaled mainstream smoke. Secondhand smoke contains at least 250 chemicals known to be toxic, including more than 50 that can cause cancer.
A 1992 Environmental Protection Agency report, Respiratory Health Effects of Passive Smoking, provides a list of a few of the 4,000 chemicals and substances in secondhand smoke, several of which are cancer causing agents, including: benzene, 2-napthylamine, 4-aminobiphenyl, nickel, polonium 210 (radioactive), nitrogen oxides, N-nitrosodimethylamine, N-nitrosodiethylamine, N-nitrosopyrrolidine , 1,3-butadiene, analine, formaldehyde, hydrazine, N-nitrodiethanolamine, cadmium, benzo[a]pyrene, benz[a]anthracene, Y-butyrolactone, particulate matter, N-nitrosonornicotine, NNK, carbon monoxide, carbon dioxide, carbonyl sulfide, toluene, acrolein, acetone, pyridine,3-methylpyridine, 3-vinylpyridine, hydrogen cyanide, ammonia, methylamine, dimethylamine, nicotine, anatabine, phenol, catechol, hydorquinone, cholesterol, quinoline, Harman, zinc, benzoic acid, lactic acid , glycolic acid, succinic acit, PCDDs and PCDFs (Dioxins, Dibenzofurans), formic acid, acetic acid, and methyl chloride.
