2021考研英语双语材料:可怕的三手烟
Thirdhand "smoke" isn't actually smoke at all. It's the residue of nicotine and other chemicals in tobacco, some of which are toxic, that remain long after active smoking is over.
三手烟其实根本不是烟。它是香烟中的尼古丁和其他化学物质的残留，其中一些化学物质是有毒的，在吸完烟很久后还能留存。
Some of these chemicals stick to surfaces, and others attach to dust particles. Still others often penetrate deep into wallboard, drapes and upholstery. As the compounds linger, they may react with oxidants or other particles in the room's atmosphere. The chemical reactions can create potentially harmful byproducts that can become airborne.
有些化学物质会附着在表面上，其他一些则会附着在粉尘上。还有一些化学物质经常会渗入墙板、窗帘和家具装饰品。在化合物停留期间，它们可能会和室内空气中的氧化物或其他颗粒发生化学反应。这些化学反应会产生有潜在危害的副产物，并通过空气传播。
A new study out of Yale University says thirdhand smoke -- the tobacco contaminants that adhere to walls, bedding, carpet and other surfaces until a room smells like an ashtray -- can actually cling to a smoker's body and clothes as well.
耶鲁大学的一项新研究指出，三手烟，即吸附在墙壁、床单被褥、地毯和其他表面的烟草污染物，让房间闻起来像烟灰缸，事实上也会附着在吸烟者的身体和衣服上。
Those potentially toxic chemicals, including nicotine, can then be released into environments where smoking has never occurred, like your movie theater, according to the study.
研究发现，(吸附在吸烟者身上的)包括尼古丁在内的这些潜在的有毒化学物质之后会被释放到没人吸过烟的环境中，比如电影院。
Even more disturbing: The study found those chemical exposure levels could be the equivalent of between one and 10 cigarettes by the end of the movie.
更让人困扰的是：研究发现，看完一场电影，暴露在这些化学物质中所受的危害相当于吸了1到10根烟。
