金特纳继续说道:“这是本研究的一个独特之处。观众身上散发出的挥发性有害有机化合物——包括苯和甲醛等已知致癌物——种类之多让我们感到惊讶。”
什么是“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。
upholstery[ʌpˈhoʊlstəri]: n. 家具装饰品(或衬垫等)
Science has known about this type of environmental pollution for years, sparking the creation of smoking and non-smoking rooms at hotels, restaurants and the like.
