"Third-hand smoke" is a new term invented by pediatricians from Boston's MassGeneral Hospital for Children. If the threats from second-hand smoke is relatively easy to be relieved by ventilating the air, those of third-hand smoke may be persistent. What's the worse is the children whose parents smoke are posed under direct threats. From New York Times:
Parents who smoke often open a window or turn on a fan to clear the air of second-hand smoke, but experts now have identified another smoking-related threat to children’s health that isn’t as easy to get rid of: third-hand smoke.
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 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.
Doctors from MassGeneral Hospital for Children in Boston coined the term “third-hand smoke” to describe these chemicals in a new study that focused on the risks they pose to infants and children. The study was published in this month’s issue of the journal Pediatrics.
...
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; arsenic; lead; carbon monoxide; and even polonium-210, the highly radioactive carcinogen that was used to murder former Russian spy Alexander V. Litvinenko[picture, wikipedia] in 2006. Eleven of the compounds are highly carcinogenic.
So for your own health as well as your family members, please stop smoking!
