Researchers at Massachusetts GeneralHospital for Children (MGHfC) have invented a new term that describes dangersassociated with cigarette smoke: third-hand smoke. Study results published in January,2009 discuss how third-hand smoke is especially dangerous for children.

Have you ever walked into a room that hadthe smell of cigarette smoke, regardless of the fact that a fan was moving theair and no one was smoking at the time? This is what researchers are callingthird-hand smoke — and it represents the poisonous deposits (存积物) that are left behind longafter a cigarette is put out. 

Cigarette smoke contains gases and smallparticles that are deposited on every surface it comes in contact with, forexample, the smoker’s hair and clothing, or the environment the cigarette wassmoked in. It’s dangerous for young children who may crawl on pollutedsurfaces. Third-hand smoke is a serious health risk for our kids, especiallythose who live in the homes of smokers.

Jonathan Winickoff, lead author of thestudy, explains, “When you come into contact with your baby, even if you’re notsmoking at the time, he or she comes in contact with those poisons. And if youbreast-feed, the poisons will transfer to your baby in your breast milk.”Winickoff adds however, that nursing a baby if you’re a smoker is still abetter choice than bottle-feeding.

Researchers involved in the study alsosurveyed more than 1,500 families in an effort to learn about adult attitudesregarding the danger third-hand smoke represents to their children and how thatmight affect smoking in the home.

Approximately 95 percent of nonsmokers and84 percent of smokers believe that secondhand smoke is dangerous for children.

On the issue of whether third-hand smokethreatens the health of children, 65 percent of nonsmokers and 43 percent ofsmokers felt that third-hand smoke harms kids. When asked about rules regardingsmoking in the home, approximately 88 percent of nonsmokers said they don’tallow smoking, while only 27 percent of smokers forbid smoking in the home.

However, both non-smokers and smokers whofelt that third-hand smoking was harmful to children’s health were moreinclined to (倾向于)restrict smoking in their homes.
