2005 New Jersey Air Monitoring Study
Restaurants, bars, casinos, and bowling alleys that allowed smoking had, on average, 15 times more indoor air pollution than smokefree restaurants and bars, as measured by the concentration of particulate matter smaller than 2.5 microns in diameter. Casinos averaged eight times more pollution than smokefree workplaces and public places.
Employees in all of the smoking-permitted locations tested were exposed to pollution that exceeded levels recommended by the U.S. Environmental Protection Agency (EPA); the average employee exposure was 3.4 times the EPA limit. Employees in all the smokefree locations were in workplaces with acceptable air quality.
