Third-hand smoke is generally considered to be residual nicotine and other chemicals left on a variety of indoor surfaces by tobacco smoke. This residue is thought to react with common indoor pollutants to create a toxic mix. This toxic mix of third-hand smoke contains cancer-causing substances, posing a potential health hazard to nonsmokers who are exposed to it, especially children.
所谓的三手烟就是烟草燃烧后残留在室内表面各处的残余尼古丁和其他有害物质。这种残留物会与普通的室内污染物起反应而产生一种有毒的混合物。这种由三手烟造成的有毒混合物是一种致癌物质,对于那些置身其中的不吸烟者,尤其是孩子,构成了潜在的健康威胁。
Studies show that third-hand smoke clings to hair, skin, clothes, furniture, drapes, walls, bedding, carpets, dust, vehicles and other surfaces, even long after smoking has stopped. Infants, children and nonsmoking adults may be at risk of tobacco-related health problems when they inhale, ingest or touch substances containing third-hand smoke. Third-hand smoke is a relatively new concept, and researchers are still studying its possible dangers.
研究显示三手烟会附着在头发、皮肤、衣服、家具、床帘、墙壁、被褥、地毯、灰尘、车辆以及其他物体表面,即使烟已经燃尽,这些附着在物体表面的三手烟依然不会马上消失。当婴儿、孩子和不吸烟的成年人吸入、摄入或触摸这些含三手烟的物质,便有可能出现疾病隐患,即有可能罹患由吸烟而引发的健康问题。三手烟是一个相对较新的概念,研究人员仍然在探索其可能存在的危险。
Third-hand smoke residue builds up on surfaces over time and resists normal cleaning. Third-hand smoke can't be eliminated by airing out rooms, opening windows, using fans or air conditioners, or confining smoking to only certain areas of a home. Third-hand smoke remains long after smoking has stopped. In contrast, second-hand smoke is the smoke and other airborne products that come from being close to burning tobacco products, such as cigarettes.
三手烟的残留物在物体表面长时间堆积后,用普通的方法难于清理,三手烟不能通过室内通风,开窗,用扇子扇或用空调换风来清理,也不能指望只在家里的某一个地方吸烟,其他地方不吸烟就可以解决问题,三手烟即使在香烟已经燃尽之后依然存在。相对来说,二手烟仅仅是来自于诸如香烟一类的烟草产品在燃烧时离烟草较近的烟以及随空气传播的其他化学物质而已。
The only way to protect nonsmokers from third-hand smoke is to create a smoke-free environment, whether that's your private home or vehicle, or in public places, such as hotels and restaurants.
保护不吸烟者远离三手烟的唯一方法就是创造一个无烟环境,无论在私人住宅或私家车上,还是在酒店和饭店这样公共场所。
