Wash U. study on secondhand smoke finds surprising results

(KMOV) -- The results of a study about secondhand smoke in St. Louis bars and restaurants has been released.
 
This is the first study specifically looking at secondhand smoke in St. Louis area bars and restaurants.
 
Researchers from Washington University and Barnes-Jewish Hospital used airborne nicotine monitors to determine the level of exposure to secondhand smoke.
 
Researchers used airborne nicotine monitors at ten bars and ten restaurants.  The study found that ventilation systems do not do a good enough job of cleaning the air for harmful smoke. 
 
In one of the most surprising findings, businesses with ventilation systems that allowed smoking had higher nicotine concentrations in the air than businesses who did not filter the air.
