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.
目的
检测中国写字楼内的二手烟暴露水平，并评估无烟政策在降低二手烟暴露方面的有效性。
方法
对来自中国10个省份的14座写字楼的吸烟政策进行调查，并测量二手烟水平。
结果
写字楼内吸烟显著提高了至少有一名吸烟者的办公室和无吸烟者办公室的二手烟浓度。在一座最近采用无烟政策的写字楼中，政策实施后尼古丁浓度显著下降。实施吸烟政策对降低写字楼内的二手烟暴露有效。
结论
中国不吸烟的办公室工作人员在工作中暴露于高水平的二手烟；中央和地方政府都应认识到有必要针对工作场所吸烟进行立法。
