A New Cigarette Hazard: ‘Third-Hand Smoke’ (from New York Times; By RONI CARYN RABIN, January 2, 2009 )
三手煙指沾付到人體頭髮衣物, 家具的有害氣體及微粒. 比方說, 走入空電梯裡聞到的煙味就是三手煙
這對吸煙者的親人, 尤其是小孩, 的健康會有影響
... That’s the term being used to describe the invisible yet toxic brew of gases and particles clinging to smokers’ hair and clothing, not to mention cushions and carpeting, that lingers long after second-hand smoke has cleared from a room. The residue includes heavy metals, carcinogens and even radioactive materials that young children can get on their hands and ingest, especially if they’re crawling or playing on the floor.
“The central message here is that simply closing the kitchen door to take a smoke is not protecting the kids from the effects of that smoke,” he said. “There are carcinogens in this third-hand smoke, and they are a cancer risk for anybody of any age who comes into contact with them.”
Among the substances in third-hand smoke are:
* hydrogen cyanide, used in chemical weapons;
* butane, which is used in lighter fluid;
* toluene, found in paint thinners;
* carbon monoxide;
* and even polonium-210, the highly radioactive carcinogen that was used to murder former Russian spy Alexander V. Litvinenko in 2006.
Eleven of the compounds are highly carcinogenic.
