摘要
目的检测室内工作场所烟草烟雾浓度,评价禁烟政策在降低烟草烟雾暴露中的作用。方法选取10个省市的14个卫生机构的办公楼,调查办公楼内的禁烟规定;用尼古丁作为烟草烟雾的标志物,评估禁烟规定对烟草烟雾暴露的作用。结果14个办公楼中,有4个实行了全面禁烟或部分禁烟规定。有禁烟规定办公楼的办公室的尼古丁浓度80百分位点低于2μg/m3,无禁烟规定办公楼的办公室尼古丁浓度80百分位点为20μg/m3。70%以上的吸烟办公室的尼古丁浓度超过1μg/m3;35%的非吸烟办公室和50%的走廊的尼古丁浓度超过1μg/m3。有1个办公楼在2006年1月1日颁布了禁烟规定,之后其尼古丁浓度大幅度下降:办公室的尼古丁平均值下降到原来的1/4以下,走廊下降到1/8以下。结论工作场所是烟草烟雾暴露的一个重要场所。禁烟或限制吸烟都可以有效降低室内烟草烟雾的暴露。
Objective To examine the secondhand smoke (SHS) exposure levels in office buildings and to evaluate the effect of smoke-free policy on reducing SHS exposure. Methods 14 health-related government offices from 10 provinces were selected and surveyed on smoke-free policy, and SHS concentrations in these buildings were detected. Nicotine was used as the marker for SHS. Results Four of the 14 office buildings executed either a smoke-free policy or a policy that restricted smoking to certain areas in the building. The 80 th percentile of nicotine concentration in offices was below 2 μg/m^3 in buildings with the policy, while 20μg/m^3 in buildings without the policy. The nicotine concentration was over 1 μg/m^3 in more than 70% of the offices with at least one smoker, while in 35% of the offices with no smoker and 50% of the hallway samples. After adopted a smoke-free policy on Jan. 1st 2006, the nicotine concentrations in a building decreased dramatically. The average nicotine concentration dropped more than 4-fold in offices and 8-fold in hallways. Conclusion SHS in workplace was one of the most significant sources of tobacco smoke exposure. Both types of policy were associated with reduced SHS concentrations in the offices as well as in the entire building.
