HCC study finds air quality significantly improved in Charleston area businesses
New findings from a study conducted by researchers at the Hollings Cancer Center (HCC) revealed significantly improved air quality in bars and restaurants in Charleston and Mount Pleasant where smoke-free ordinances were implemented last year.
With a 94 percent reduction in air pollution, the air quality in the places included in the study fell well within safe limits set by the U.S. Environmental Protection Agency (EPA), said HCC cancer control specialist Matthew Carpenter, Ph.D., who led the study.
“We know that hospitality employees are exposed to secondhand smoke, which is an established cause of lung cancer,” Carpenter said. “These results show that smoke-free legislation effectively reduces exposure and that such legislation protects hospitality employees from a known cancer risk.”
The study began in 2006 when the researchers analyzed air quality in 23 venues that allowed smoking in Charleston and 11 in Mount Pleasant. These same venues were tested again in 2008 following passage of local smoke-free ordinances. The city of Charleston established a smoke-free ordinance in public places in July 2007; Mount Pleasant followed with a similar ordinance in September 2007.
The study also examined air quality in 10 establishments in North Charleston, which does not have a smoke-free ordinance, and found that air pollution there remains more than three times higher thanEPA considers safe.
“Everyone has the right to breathe clean air, especially at work,” said Dianne Wilson of the South Carolina African-American Tobacco Control Network, who funded the study. “These tests show that workers protected by smoke-free ordinances have a tremendous health advantage over workers in cities that have failed to pass protective measures.”
The study’s findings were independently reviewed by Roswell Park Cancer Institute in Buffalo, N.Y.
