目的：了解我国写字楼二手烟(SHS)暴露水平，评价无烟政策对降低SHS暴露的效果。方法：对中国市区10个省的14栋办公楼进行吸烟政策调查和SHS水平测定。结果：无论是在至少有一名吸烟者的办公室还是在没有吸烟者的办公室，在大楼内吸烟都显著增加了SHS的浓度。在最近采取无烟政策的一栋建筑中，政策实施后尼古丁浓度显著下降。制定吸烟政策有效地减少了建筑物内的SHS暴露。结论：中国不吸烟的上班族在工作中暴露于显著水平的SHS，中央和地方政府都应该意识到立法禁止工作场所吸烟的必要性。
Objective: To examine the secondhand smoke (SHS) exposure level in Chinese of 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.
