为了避免香烟烟雾的困扰，你费尽心机寻找无烟酒店入住。即便如此，你仍然可能暴露在他人吐云吐雾的“魔爪”里。
新近刊登在《Tobacco Control》的一项研究发现三手烟同时存在于部分禁烟酒店内吸烟和非吸烟房间里。
三手烟是指烟民“吞云吐雾”后残留在衣服、墙壁、地毯、家具甚至头发和皮肤等表面的烟草烟残留物。美国能源部下属伯克利劳伦斯国家实验所的研究人员发现，这些残留物可存在几天、几周甚至数月。他们首次评估了室内环境下尼古丁接触空气中常见物质后的反应，发现尼古丁与常见空气污染物亚硝酸接触后可形成强大的致癌物（室内亚硝酸主要来自燃气设备）。
该项研究共收集了10家完全禁烟酒店和30家部分禁烟酒店（提供专用吸烟房间）的空气和尘埃样本，检测尼古丁和3-乙炔基吡啶（3EP）含量。同时他们还收集了酒店客人的手掌灰尘和尿样检测吸烟相关代谢物含量。
结果显示较完全禁烟酒店，部分禁烟酒店的空气和尘埃样本中的尼古丁和3EP含量更高。而与此印证的是，入住部分禁烟酒店的客人手掌灰尘和尿样中的吸烟相关代谢物含量更高。
研究者认为部分禁烟的酒店并不能保护客人免受香烟烟雾和香烟特异性致癌物的暴露，建议非吸烟者入住完全禁烟的酒店。
Non Smoking Hotel Rooms Can Still Expose You To Smoke
Think you're saving yourself from cigarette smoke by booking a non-smoking hotel room? Think again.
A new study in the journal Tobacco Control shows evidence that "thirdhand smoke" -- which is air that's been polluted by tobacco smoke -- is present in both smoking and non-smoking rooms.
"Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens," San Diego State University researchers wrote in the study. "Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective."
The study included surface and air samples from 10 hotels with complete smoking bans and 30 hotels with partial smoking bans (where some rooms are designated nonsmoking rooms, while others are designated smoking rooms). Researchers analyzed the samples for pollutants, including nicotine and 3-ethynylpyridine (known as 3EP). Researchers had study participants who stayed in these rooms give finger wipe and urine samples so that they could detect any potential cigarette smoke-related chemicals there, too.
Researchers found higher levels of the nicotine and 3EP pollutants in the air and surface samples taken from hotel rooms with partial smoking bans, compared with rooms with complete smoking bans. Plus, people who stayed in the partial-smoking-ban hotel rooms had higher cigarette pollutant levels on their fingers and in their urine than those staying in the rooms where hotels didn't allow any smoking.
