Effectiveness of a smoke-free policy in lowering secondhand smoke concentrations in offices in China

J Occup Environ Med. 2008 May;50(5):570-5. doi: 10.1097/JOM.0b013e3181638640.


Objective: To examine the secondhand smoke (SHS) exposure level in Chinese office buildings and to evaluate the effectiveness of a smoke-free policy in reducing SHS exposure.

Methods: Survey of smoking policies and measurement of SHS level in 14 office buildings from 10 provinces in China.

Results: Smoking in the building significantly elevated the SHS concentrations both in offices with at least one smoker and in offices with no smokers. In one building that recently adopted a smoke-free policy, the nicotine concentrations decreased significantly after the policy was enacted. Enactment of a smoking policy was effective in reducing SHS exposure in the buildings.

Conclusions: Nonsmoking office workers in China were exposed to significant levels of SHS at work; both the central and local governments should realize the need to legislate against workplace smoking.
