What carcinogen does low tar cigarette lower too burntly to reduce containing while hurting tar?
Drafting of The Beijing News / Gu LeXiao The medical circle has endangered the propagation and education doing one's utmost in smoking and let a lot of people realize the danger of smoking for a long time, but on the other hand even give and brag about the low tar cigarette which reduced danger to offer the enormous market. " filter tip " , " low tar " Wait for every introduction of new technology to sell and bring a new climax to cigarettes. And the influence brought around the new technology, disputing has not been stopping all the time. Some experts and scholars regard the low tar cigarette as another fraud of the tobacconist's, but some people in the industry think the appearance of these new technologies is really to start from crowd's healthy consideration to smoking. Which is right and which is wrong to judge the two, perhaps we should be from understanding low tar cigarette begin first. The person often smoking in test result of the machine that the tar quantity of the cigarette is only, are certainly relatively familiar with a group of figures by the cigarette cast, " tar amount " among them A number value which the crowd relatively cares about that one are to smoke. Tar amount has reflected the taste of the cigarette to a certain extent, and the sense of achievement brought to smoker. The more important thing is to contain benzene and combine Zhyuan in tar, cadmium, arsenic, bitter edible plant, amine, inferior the intersection of nitre and the intersection of amine and radiosiotope,etc. and many kinds of carcinogen and phenol, rich horse to urge cancer and material. It says, according to the national standard, it is low tar content that the tar content is smaller than 15 milligrams in each cigarette to accuse of Yang GongHuan, director of cigarette office, in the whole country. Tar content of most cigarettes of the domestic market is basically about 10 milligrams. Quantity milligram of cigarettes as to tar, most people will regarded as cigarette tar itself include total amount 10 milligrams, this idea has been actually misleading a lot of people all the time. Yang GongHuan says, the tar quantity of the cigarette is not the tar quantity sucked in the cigarette in fact, but a piece of test value obtained through behavior of smoking of the simulation people of the test machine. The tar quantity that the test machine suck does not mean the tar amount American Federal Trade Commission (FTC) that people suck Measure the nicotine and tarry content in cigarettes with test machine since 1967, announce each kind of test result. Explain tar quantity that test machine suck, mean the tar quantity that people suck already when FTC tested, because people's habit of smoking is the machine can't be imitated. For example the test machine smokes the cigarette for two seconds every minute, the depth of frequency and breath that and the person smokes is different from machine. "These personal habits have very great relations to tobacco burning intensity and tar producing amount, not this point of the tar quantity which the representative suck really of result that crowd tests for machine of smoking does not have enough understanding. " The active charcoal of secret of the filter tip is filtered, " draught " Dilute exhaust gas some tar of cigarette quantity even low to reach 3, a lot of people regarded as processed with special-method tobacco or garniture, let tar content of cigarette these reduce, but the greatest possibility of the contribution is an unattractive filter tip in fact. The rank of the filter tip seems to be an important standard of distinguishing the price of cigarette too. A lot of low tar cigarettes can see the filter tip extended, but the key that the filter tip contributes is not totally length, and lie in its internal structure. When we observe the filter tip of the low tar cigarette carefully, will find the draught that two naked eyes will be difficult to see in about 1.5 centimetres of terminal places of filter tip. Regard these two draughts as the broken line, can break filter tip off with the fingers and thumb two into to cut, also contain the black particulate matter in filter tip of that side close to the tobacco. Yang GongHuan says, most cigarette filter tips are made of acetic acid cellulose, filter some tar, dust and nicotine through the tiny hole in the filter tip. Besides this, the filter tip of the low tar cigarette is usually divided into two parts, will add the active charcoal close to one end of the tobacco, communicate with the external world through one to two draughts between two sections of filter tips yet. "On one hand low tar quantity cigarette filters some tar and nicotine by the filtration ability and active charcoal among them of the filter tip, on the other hand suck the air and dilute the exhaust gas through the draught. Will let people feel smell dish of cigarette sucked is lighter through such a way. " Active charcoal part after smoking. Do not include the filter tip of the active charcoal part after smoking. Active charcoal part before smoking. Do not include the filter tip of the active charcoal part before smoking. The cigarette " The draught " . Staff reporter He Xiao takes the photograph It indicates the low tar cigarette is unsafe though cigarette manufacturers let the tar content of the cigarette in test be reduced through all sorts of methods to decipher the epidemiology research of low tar, the mouthfeel becomes soft, but the danger of the cigarette seems not to reduce because of these measures. Breathing epidemic disease chief of research office Xiao Dan of research institute of disease in Beijing says, in nearly half a century, very big change has taken place in the type of the cigarette, the tar amount reduced 60% compared with before, but a lot of epidemic disease investigations all indicate these changes have not changed the danger of the tobacco. The cigarette which uses the low tar content has not reduced the trend that lung cancer has illness coming on, smoking remains the main endangering the factor high of lung cancer. " some research shows in the world at present in the morbidity type that the cigarette with the filter tip has only changed cancer, the morbidity that the cigarette with the filter tip has not lowered cancer, has just changed the morbidity type of cancer. For example the big particulate matter in the exhaust gas is apt to enter the respiratory tract without filter tip before this, deposit at likely to suffer from flat bronchus of epithelial cancer, bring out flat upper lung cancer of peel type. After and there are filter tips, the smoking crowd, in order to suck more nicotine, inlet the smog of cigarette into the lung depths. This probability of bringing about the canceration in body of gland of the lung tip increases, thus make the morbidity of gland cancer rise. In addition animal's experiment still proves nitric acid of more content burns the inferior ammonium nitrate turned into in the low tar cigarette, it is the peculiar carcinogen which brings out gland cancer. " Except that the probability of bringing out lung cancer has not been reduced, smoking was not reduced to the influence of vascular disease of the heart brain either. Xiao Dan say, the cigarette of the filter tip though tar quantity was reduced, the soakage of the carbon monoxide has risen by about 40%. And the carbon monoxide is involved in myocardial infarction, angina pectoris risk. "There is a urine test of measuring the cigarette to high, normal, basic tar in the world, indicated finally metabolite content of several kinds of carcinogen did not have statistics difference in three groups of crowd's urine, prove the cigarette of low tar quantity has not been reduced in the danger to the human body of the carcinogenic respect. These prove low the intersection of tar and the intersection of quantity and cigarette become safer at theory and practice by experiment and the intersection of epidemiology and data. " Suck the intersection of tar and quantity with the intersection of cigarette and the intersection of tar and content, directly proportional to work Yang, shine, say, the danger that low tar measures the cigarette is not lower than the ordinary cigarette, " in the same way of smoking, it is low and burnt The oil content is certainly better than the high tar content. But smoke?

Besides this, even if according to a cigarette, low the intersection of tar and the intersection of quantity and tar that cigarette produce finally quantity may not lower than the ordinary cigarette either. Yang GongHuan says, tar of cigarette organic burnt things and is produced on condition that totally burnt, the tar quantity that man a cigarette suck finally actually and personal behavior are used to having very great concerning. For example some smokers think the taste of the low tar cigarette partial and light, increase and suck the density of the cigarette by stopping up the draught, increasing the method to suck speed and depth, the tarry quantity that these methods will cause a cigarette to produce finally increases. It is reminded that relevant Do not " have ripe wine " It is in fact low alcohol Li DeMei, committee member of technical committee of Chinese wine " there is no ripe wine " at first Itself is a fallacy, there is no ripe wine that is actually only a low ripe wine, really realizedding has no alcohol, can't call it the wine any more. In our country's current wine national standard GB15037-2006 " The special wine " Name,is it low to have alcohol wine (alcohol 1.0-7% of contents) With taking off the wine of alcohol ' 0.5-1% of alcohol content) . No matter " There is not alcohol " " take off alcohol " ,Their content of alcohol is greater than 0.5%. It is a gag that there is no wine of alcohol to play health card, this is undoubted. Whether low alcohol or high alcohol, so long as drink in right amount, does not have great danger to the health. So long as excessive, no matter your low alcohol high alcohol, so long as it is the same to include the alcohol result, the health is not known where to begin.
