THE EFFECTS OF ALTERNATIVE SMOKING POLICIES ON INDOOR AIR-QUALITY IN 27 OFFICE BUILDINGS

The effect of alternative smoking policies, which prohibited or restri cted smoking, on indoor air quality was studied in 27 air-conditioned office buildings. Carbon monoxide, carbon dioxide, respirable particul ates, formaldehyde, ultraviolet particulate matter (u.v.PM), nicotine, air temperature, relative humidity and illumination were measured at eight sample sites in each building. Smoking policy had no effect on c arbon monoxide, carbon dioxide, relative humidity, formaldehyde, air t emperature or illumination for open office areas. It did have an effec t on levels of respirable suspended particulates, ultraviolet particul ate matter and nicotine.
