" Three hand cigarettes " Endanger the health too Difficult strick precaution of nicotine residues
As everyone knows, smoking is harmful to health, it is a cancer inducement; " second hand smoke " With " the cigarette all alone " Have the same carcinogenic function. A latest research in U.S.A. reveals, " three hand cigarettes " Endanger the health too, carcinogenic.

The research report is issued in the latest American " journal of national academy of sciences ".

" three hand cigarettes "

So-called " three hand cigarettes " ,Refer to smokers " Swallow clouds and blow out fog-smoke (opium or cigarette) " And then remain in superficial tobacco cigarette residue such as clothes, wall, carpet, furniture, hair and skin.

American the intersection of Ministry of Energy and subordinate national the intersection of experiment and researcher, Laurence of Berkeley, find, these residues can exist for a few days, several weeks even several months.

The lower nicotine of internal environment of their first evaluation room contacts the response after the common material in the air, react and can form strong carcinogen after finding nicotine and common air pollutant inferior nitric acid. Indoor inferior nitric acid mainly comes from the gas apparatus.

Researchers regard existing the cellulose of things in the sofa cushion, weaving as the model of representative of indoor materials, use the intersection of exhaust gas and smoked it first, then locate it " high density reasonable " Inferior for nitric acid hour such as 3 pieces in environment,find whether than originally 10 times higher tobacco nitre amines inferiors characterized that be produced finally, and to produce the speed is faster.

They have also measured a " cigarette addict " 45 years old Truck inside,last tobacco nitre amines inferiors characterized that is high-load. Inferior nitric acid in the car mainly comes from the engine, can permeate through this carriage.

It is difficult to take precautions against

It is said that one of the research report authors, chemist's rain fruit morality tower are inferior: "Research reveal, remain nicotine and inferior nitric acid in the air can produce tobacco characterized inferior nitre amine after reacting. Tobacco characterized inferior the intersection of nitre and amine to know, exist on fire extensive effective carcinogen one of in tobacco and exhaust gas. "

Discover, open the window while smoking or can't totally remove " three hand cigarettes " to turn on the fan ,The smoker is not enough to take precautions against either to outdoor smoking " Three hand cigarettes " .

"Though get, smoke than suck, take better indoors while being outdoor, nicotine residue still can affix to the smoker's skin or clothes, "" after it gets back to the room with the smoker that report to another author and draw the cured tribute Del and say, will spread to every place. "

Researchers have tested the indoor stability of these inferior nitre amine, found finally inferior nitre amine only less than 50 can be totally degraded in 2 hours after the exhaust gas is dissipated, the rest can't be degraded.

Treat deepening

Tobacco characterized inferior nitre amine is a kind of inferior nitre amine that can cause animal's mutation already verified.

People exposed to inferior the intersection of nitre and the intersection of amine and most possible route keep in touch surface ' For instance clothes, skin, furniture,etc.) Keep in touch with the dust. Infant and pre-school children often climb or play on the ground, catch the things and put into mouth, they may touch it more than the adult, the risk that the health damages is greater too.

University of California " The relevant disease research of tobacco " Have subsidized the above-mentioned research in project. Nurse's profit assorted A of staff member's card of this project asks for and specially draws and says: "We know, it may be carcinogenic that the nicotine remains the product reacting with inferior nitric acid through studying, and the present research conclusion may be the iceberg corner. "

James and Pan KeFu participating in studying says, the security production queries to the electronic cigarette of people that may make to study the conclusion. The electronic cigarette is a kind of cigarette substitute products not burnt, contain battery, nicotine box and sprayer in its metal tobacco pipe. The user can suck the nicotine of the evaporation, and breathe out white fog.

Researchers advise banning on opium-smoking and the opium trade even the person who makes regulation looks like one " The second hand smoke " List in, ban on opium-smoking and the opium trade, make the same, to " three hand cigarettes " Make the corresponding regulation. (Qiao Ying)
