目的了解大连市内四区部分公共场所空气中尼古丁的暴露水平,为控烟工作提供参考。方法选取大连市区29家公共场所,在63个检测点悬挂被动式尼古丁采样器采集环境空气中尼古丁并进行实验室检测。结果空气中尼古丁检出浓度为<0.35~3.18μg/m~3,检出率为71.43%,不同采样点间检出率差异有统计学意义(P<0.05)。结论大连市区公共场所环境烟草烟雾的暴露不容乐观。
Objective To understand the level of nicotine exposure in the air of some public places in four districts in Dalian, and to provide reference for tobacco control work. Methods A total of 29 public places in Dalian city were selected. Passive nicotine samplers were hung at 63 test sites to collect nicotine in ambient air and perform laboratory tests. Results The detection rate of nicotine in the air was <0.35 ~ 3.18μg / m ~ 3 and the detection rate was 71.43%. The detection rate of nicotine in different air samples was statistically significant (P <0.05). Conclusion The exposure of environmental tobacco smoke in public places in Dalian is not optimistic.
