Respirable particles and carcinogens in the air of delaware hospitality venues before and after a smoking ban.
ABSTRACT How do the concentrations of indoor air pollutants known to increase risk of respiratory disease, cancer, heart disease, and stroke change after a smoke-free workplace law? Real-time measurements were made of respirable particle (RSP) air pollution and particulate polycyclic aromatic hydrocarbons (PPAH), in a casino, six bars, and a pool hall before and after a smoking ban. Secondhand smoke contributed 90% to 95% of the RSP air pollution during smoking, and 85% to 95% of the carcinogenic PPAH, greatly exceeding levels of these contaminants encountered on major truck highways and polluted city streets. This air-quality survey demonstrates conclusively that the health of hospitality workers and patrons is endangered by tobacco smoke pollution. Smoke-free workplace laws eliminate that hazard and provide health protection impossible to achieve through ventilation or air cleaning.

ABSTRACT: Natrona County, Wyoming. Four locations were smoke-free and 15 locations permitted indoor smoking. The concentration of fine particle air pollution, PM 2.5 , was measured with a TSI SidePak AM510 Personal Aerosol Monitor. PM 2.5 is particulate matter in the air smaller than 2.5 microns in diameter. Particles of this size are released in significant amounts from burning cigarettes, are easily inhaled deep into the lungs, and cause a variety of adverse health effects including cardiovascular and respiratory morbidity and death. Key findings of the study include: • In the 15 locations with observed smoking, there were, on average, 5.9 cigarettes burning during the visits. This translates to an average of 1.37 burning cigarettes per 100 cubic meters of air in these places. • In the 15 locations with observed indoor smoking the level of fine particle air pollution was very unhealthy (PM 2.5 = 224 µg/m 3). This level of particle air pollution is 45 times higher than outdoor air in Wyoming and 56 times higher than the smoke-free locations. • Employees working full time in the locations with indoor smoking are exposed to levels of air pollution 4 times higher than safe annual levels established by the U.S. Environmental Protection Agency due to their occupational exposure to tobacco smoke pollution.
