 Abstract
Background: Dong-Seoul station is a place with a large floating population. They had many tobacco-related complaints, because outdoor smoking facility was placed near a popular gathering location. The objective of this study was to determine outdoor tobacco smoke exposure before and after moving the outdoor smoking facility in Dong-Seoul station.
Methods: Outdoor PM2.5 concentrations near Dong-Seoul station were measured at various locations based on the existing outdoor smoking facility. Measurements were conducted 5 times before moving the smoking facility and one time after moving the smoking facility. PM2.5 concentrations by particle spectrometer (SidePak, TSI) were adjusted after subtraction of daily ambient PM2.5 concentrations. Peak analysis was performed.
Results: Before moving the outdoor smoking facility, PM2.5 concentrations near the smoking facility (0 m) was higher than the other measurement sites. The peak occurrence rate at 0 m was the highest with17.6 peak/10 min. After moving the smoking facility, PM2.5 concentrations at 0 m was lower than the background concentration and PM2.5 concentration at 110 m with the new smoking facility was similar to ambient concentration. The highest peak occurrence rate was observed at 90 m with11 peak/10 min.
Conclusions: Outdoor tobacco smoke near a busy bus terminal was changed after moving of outdoor smoking facility. Moving outdoor smoking facility was effective to reduce outdoor tobacco smoke exposure to pedestrians.
