Bar, casino workers benefit from no-smoking rule
A study of the effects of Delaware's ban on smoking in public places, enacted in 2002, showed that toll collectors in a tunnel tollbooth breathed fewer particulates than workers in casinos in that state, according to results published in the September issue of the Journal of Occupational and Environmental Medicine. A researcher measured air quality at eight indoor entertainment establishments before and after the law took effect, as well as at locations with high vehicular traffic.
The study found that before the smoking ban, the levels of potentially dangerous particulates in the entertainment locations were more than double the level on Interstate 95 in Delaware. But after the law took effect, particulates in the air in the bars and casinos dropped 90%. The author of the study wrote that the findings disprove the argument that good ventilation systems are enough to clear particulates from indoor air, and that the ban on indoor smoking should result in better respiratory health for workers.
