The pollution of waterhead of air increases the cancer morbidity
Brief content:An extremely important reason why cancer takes place that environmental pollution is to lead to the fact, there is about 30 multi-type of material on carcinogenic function in the atmosphere, among them benzene of multiloop fragrant hydrocarbon combines Zhyuan, it is the main carcinogen in the air pollution. Smoking is not only apt to be carcinogenic, also bring out the person around and suffer from cancer, the heavier the pollution of waterhead is, the higher the morbidity of hepatocarcinoma is.
Study materials, indicate environmental pollution to lead to the fact a extremely important reason that cancer take place in a large amount, depend on the strength of the whole society, take the comprehensive measure, manage environmental pollution effectively, it is the important component of the comprehensive precautionary measures of cancer. Its main content includes the following several respect:
1. Air pollution
A lot of scholars find, in the past 50 years, with the development of industry and economy in surprise, the improvement of people's living standard, the morbidity of lung cancer is improved notably too, especially the lung cancer patient of the developed area of the world increases at double.
For example lung cancer of U.S.A., in the 50 years such as patient, men increased by 18 times, the woman increased by 6 times, every 4 cancers die in the case, one is lung cancer; In every 100 death patients. 5 die of lung cancer. Analyse on my national conditions condition, lung cancer has the tendency to obviously increase too. Lung cancer mortality increased by 9 than 1952 in the 1971 of gulf district of reed of Shanghai. 65 times; Lung cancer mortality increased by 2 than 1958 in 1975 in Beijing City Area. 5 times. Arrange the order to look from national malignant tumour, lung cancer occupies the 5th place, in every 100 cancer patients, probably 8 suffer from lung cancer.
Why does ill rate of lung cancer increase the speed like this? The development of this and modern industry and communication and transportation business, lead to the fact the air pollution can not be separated. The intersection of atmosphere and seriously polluted industrial area and the intersection of air pollution and lighter countryside, the intersection of lung cancer and morbidity have prominent fact of difference explain this effectively.
Animal's experiment proves, multiloop charcoal hydrogen compound in the air pollutant has carcinogenic function. In the developed in industry area, can emit various smoke and dust, metal dust, fiber and various chemical materials in the industrial production process, such as benzene combines Zhyuan, nitrogen oxide, hydrocarbon, photochemistry oxidant,etc.. In daily life, kitchen range, smoke and dust, sulfur dioxide that the boiler emitted, benzene that the means of transportation discharges combines Zhyuan, nitrogen oxide, hydrocarbon,etc.. These materials are discharged and sucked in the atmosphere directly, can bring out malignant tumour such as many kinds of disease and lung cancer. The experiment proves, there is about 30 multi-type of material on carcinogenic function in the atmosphere, among them benzene of multiloop fragrant hydrocarbon combines Zhyuan, it is the main carcinogen in the air pollution.
In view of the above-mentioned situation, must strengthen the scientific overall arrangement of the industrial area conscientiously; Pay attention to reducing the waste gas and discharging and discharging the harmless treatment of the waste gas; Launch the mass afforestation environment, purify the air and work; Do the personal protection well, go out to wear and protect the gauze mask,etc. if necessary. This danger to the human body for reducing the atmosphere, the morbidity of lowering malignant tumour such as lung cancer will be of great advantage.
What deserves to be mentioned is, while paying attention to air pollution carcinogenically, to the air pollution incurred because of smoking, especially the danger that the indoor air pollution brings can't be ignored either. There is such a story that has clearly explained this.
-An old man over 70 years old, over the past 60 years, his mouth from morning till night has stopped releasing from the smoke. Its spouse and he are of the same age, suffering from lung cancer five years ago deads, but his lung X-ray examination was that " the heart and lungs were normal " ,Therefore, he will cause the statement of cancer to produce suspicion in smoking. Then, what reason is this on earth?
Research in recent years open answer to a riddle finally, originally, contain, harmful to compositions while being many kinds of in the smog of smoking, this is apt to activate benzene to combine Zhyuan to person that carcinogen enzyme is active and strong, help make it from bad to worse, make benzene and Zhyuan play a carcinogenic role. And play a role in not activating to the person that carcinogen enzyme is active and weak, benzene combines Zhyuaning. Its spouse is forced to smoke because of living in the environment of smoking, the hydroxy enzyme activity of internal aromatic hydrocarbon is stronger, then has become the innocent victim that the old man smokes. And though old man is the initiative smoker, the activity of this kind of enzyme is relatively weak in the body, a large amount of benzene and Zhyuan can't be activated but not suffer from cancer by sheer good luck. Therefore can know, smoking not only influences one's own health seriously, meanwhile, also a kind of threat to others' life security.
There are materials that are pointed out: When the smoker smokes, I only suck into 30% smog, but other 70% smog distributes in the surrounding environment, if ventilate in the room badly, a large amount of smog is sucked with the person in the room then become the passive smoker, then has increased the chance of contracting cancer too. For this reason, we advise smokers, except that in order to think about healthily one's own, should pay attention to the public morality even more, do not smoke, does not especially smoke in the public place.
2. Pollution of waterhead
In the course of investigating cancer has illness coming on, people find such a pondered-over phenomenon: Even in the same hepatocarcinoma high are taken place to the county, high hair and extremely clear boundary line of low hair exist, and too long-term to change; Some only that one piece of highway through,last 6-7 time. The investigation finds again, this kind of phenomenon relates to the fact that drinking water sources are different. The low residents of taking place area rely mainly on drinking great river running water and well water, and high taking place area residents, in order to drink water of ditch pool as the main fact. Water of ditch pool sees more low flat area on the seashore, much bad smell of well water of seashore is salty, not suitable for drinking; And water of ditch pool is lightly seasoned, not only the source of water of drinking the water, also it is also that one kind urge the cancer pharmaceutical to use for washing the clothes (detergent, so can't enter the mouth) , vegetables, night-soil bucket,etc.,last some aquatic products, therefore source of water is seriously polluted.
The further investigation finds again, the more serious the pollution of waterhead is, the higher the morbidity of hepatocarcinoma is, the pollution of waterhead is relatively light, the morbidity is relatively low too. The morbidity of hepatocarcinoma of the person who drinks water of ditch pool drinks 6 times and 12 times of shallow well water, deep well water. Until high three the intersection of township and about 50,000 people that take place investigate result drink the intersection of ditch and the intersection of pool and the intersection of water person and morbidity most high hepatocarcinoma specially to some county, secondly the river, but the person who drinks deep well water, shallow well water has not had illness coming on. In addition, it is at Jiangsu Qidong and at remit Hainan by hotspot,until there set up is resident about 160,000 people in 16, register the type of drinking the water, then track that observes the morbidity situation of its hepatocarcinoma, it is correct to reconfirm the above-mentioned conclusion through following up a case by regular visits to for many years, meanwhile, a lot of emergence and drinking water of cancer clean to closely related with. Investigation result brief on will certainly store carcinogen in in the intersection of ditch and the intersection of pool and water.
In addition, with the swift and violent development of the industry of our country, every big river system and tributary of our country, and some city groundwater has already received the chemical material in various degree - -The pollution of mercury, cyanide, phenol, chromium, arsenic, petroleum,etc., has and already caused the difference
