Matthew Lamkin : Perhaps it would be wise to globally review your PWB storage policies in general. With regard to smoking, seek a volunteer who routinely smokes in his (her) car and apply paper towel and Windex. I believe you will see the effect. Tobacco smoke is made up of "sidestream smoke" from the burning tip of the cigarette and "mainstream smoke" from the filter or mouth end. Tobacco smoke contains thousands of different chemicals which are released into the air as particles and gases. Many toxins are present in higher concentrations in sidestream smoke than in mainstream smoke and, typically, nearly 85% of the smoke in a room results from sidestream smoke [1]. The particulate phase includes nicotine, "tar" (itself composed of many chemicals), benzene and benzo(a)pyrene. The gas phase includes carbon monoxide, ammonia, dimethylnitrosamine, formaldehyde, hydrogen cyanide and acrolein. [1] US Surgeon General. The Health Consequences of Smoking: Chronic obstructive lung disease. USGPO, 1984. Perhaps, the most generous solution is a separate break room which has been utilized by schools for years and more recently department stores like Sears & Roebuck; the most abhored solution, banning; or the middle road idea in the States is outdoor areas. Good luck, Paul P.S. It would really be interesting if there was effective way to quit.
