Objectives: The aims of this study were to determine the indoor level of environmental tobacco smoke (ETS) and to assess the implementation rate of smoke-free laws at hospitality venues around a university campus by measuring particulate matter smaller than 2.5 ㎛ (PM2.5) as an indicator of ETS.
Materials and Methods: We measured indoor PM2.5 concentrations at 20 PC game rooms, 20 pubs, and 20 billiards halls using Sidepak AM510, a direct reading portable real time monitor, from October to December 2015.
Results: Smoking was observed in 65% of the PC game rooms, 10% of pubs, and 85% of billiards halls. The average PM2.5 concentrations were 98.2 ㎍/㎥, 29.0 ㎍/㎥, and 134.2 ㎍/㎥ at PC game rooms, pubs, and billiards halls, respectively. PM2.5 concentrations in PC game rooms and billiards halls were 2 to 2.7 times higher than the 24-hour exposure standard for outdoor PM2.5 (50 ㎍/㎥) by the Ministry of Environment.
Conclusions: Although a smoking ban has been implemented for PC rooms and pubs, smoking is still taking place in many of these places. More stringent legal action is required for successfully protecting patrons and workers from secondhand smoke exposure. A ban on smoking in billiards halls should be introduced as quickly as possible.
