Study: Indoor air quality improves since smoking ban

SAVANNAH, GA (WTOC) -

Indoor air quality has vastly improved at several venues that went smoke-free in 2011, according to a study by the Department of Health Behavior and Aerosol Pollution Exposure Research Laboratory at Roswell Park Cancer Institute.

The city of Savannah's smoke-free ordinance went into effect in 2011. The study shows a 94 percent decline in very unhealthy particle pollution levels at those businesses. The study was spearheaded by the Chatham County Health Dept.

Volunteers measured fine particle emissions inside of 11 businesses where patrons were smoking in August 2010, according to the Coastal Health District. Some personal aerosol monitors registered levels deemed "very unhealthy" by the U.S. United States Environmental Protection Agency's Air Quality Index, according to the Coastal Health District.

In November 2011 the air quality at those same 11 locations registered a "good" rating.

The study found that employees and patrons in Savannah bars and restaurants with indoor smoking, prior to the smoke-free air law, were exposed to harmful levels of indoor air pollution resulting from indoor smoking, according to the Coastal Health District.
