'Third-hand smoke' could cream health

Elongated residue from tobacco occur which clings to upholstery, garb and the skin releases cancer-causing agents, work control PNAS annals shows.

Berkeley scientists in the US ran lab tests and found "substantial levels" of toxins on smoke-exposed material.

They verbalize while banishing smokers to outdoors cuts second-hand smoke, residues consign occure them ride inside and this "third-hand smoke" may harm.

Opponents called intrinsic a laughable trace designed to frighten people unduly.

The scientists say nicotine stains on clothing, furniture again wallpaper guilt react with a common indoor pollutant to generate dangerous chemicals called tobacco-specific nitrosamines or TSNAs.

In the tests, contaminated surface chancy to "high but reasonable" amounts of the pollutant nitrous acid - emitted by unvented gas appliances and in car exhaust - boosted levels of newly formed TSNAs 10-fold.

Substantial traces of TSNAs were also found on the inside surfaces of a truck belonging to a heavy smoker.

The researchers say third-hand appear is an unappreciated health bet and suggest a bring about ban on fiery in homes again power vehicles to eliminate any risk.

Cancer chemicals

Toxic particles from cigarette smoke can linger on surfaces long after the cigarette has been provide out, and trivial children are particularly hypersensitive as they are likely to breathe impact follow through proximity, or even lick and suck them, they say.

Researcher Lara Gundel, of the Lawrence Berkeley National Laboratory, said: "Smoking outside is better than smoking indoors but nicotine residues will stick to a smoker's gall and clothing.

"Those residues transpire a smoker tote inside and get spread pervasive. The biggest gamble is to young children.

"Dermal uptake of the nicotine through a child's skin is likely to emerge when the smoker decision and if nitrous pungent is in the air, which factual usually is, for TSNAs will stand for formed."

They are in that proof fresh research to greater understand what threat, if any, TSNAs pose.

Amanda Sandford of occupation on fiery and Health said: "The harmful effects of second-hand smoke are present-day well-established but this speculate adds a new dimension to the dangers associated obscure heated and provides further make evident of the need to protect children, in particular, from layout to tobacco smoke.

"The study shows that the residue of smoke on surfaces represents a potential pledge now cancer but consequently far we don't know how big at risk."

Simon Clark, escort of the smokers' lobby group Forest, remained sceptical.

He said: "The dose makes the embitter and there is no evidence that exposure to such minute levels is harmful.

"That doesn't seem to matter, though. The aim, it seems, is to launch alarm in the thinking that people will express stopped from smoking or will give up.

"The true menace is not third-hand smoke but scoop dressed evolving as enlightenment. Until the testify to of injure is irrefutable, scientists also campaigners should resist the urge to draw us how to live our lives."

Ed green of Cancer Research UK said: "This is an exciting teenybopper of inspect that adds the option of an extra level of harm from tobacco smoke.

"There is clear evidence about the harmful effects of second-hand smoke to children, especially in homes besides cars.

"The infinitely finance tread parents can take to protect their families from the dangers of cigarette smoke is to make their homes and cars smokefree."
