The atmospheric quality in the city of China faces how the test prevents " the haze is endangered " ?
As industrialization, urbanized process are accelerated, the motor vehicle is increased sharply fast, the atmospheric quality of the city of China is facing the unprecedented test, and disease that it brings of haze is found like becoming the focus that the public is caring about high. Since last winter, the weather of numerous haze has appeared in succession in Beijing area, when the haze appears, the air is muddy, dark scenery such as the distant mountain, forest are light blue, the sun is yellowish. Light Wei, civilian of office liking to be beautiful, go out and can all tidy up oneself to dress up beautifully each time. At dusk one day, it is obscure, small Wei finds any food of family not to have, can not dress up, the supermarkets of 200 meters buy the food opposite to reaching the Residential Area directly. Such time, come back to find, on one's own face, are especially all suffused with red swelling to stand up around the lip, around eyes, and itch. She of a bit medical general knowledge, thinks of the advance notice index of the haze of the same day higher, expect at once oneself is possible " The haze is allergic " ,Wash the face, gargle, clear up the nasal cavity at once, skin care, tidy up the consequence rightly and become effective once. "The treating method of small Wei is right. " Air force general hospital infect, control the Guangxi Zhuang Autonomous Region director say certainly the Jin Dynasty such as Cao such as department. According to his introduction, the pollution factor that the haze weather is main is the haze. Limited to existing air measure competence and lagging of means, haze this new healthy killer is neglected for a long time, that the public protects knowledge relatively deficient, leave the enormous public health hidden danger. The danger haze of the haze means impurity such as a large number of dust, smoke one, salt powder swim in the sky in the gas-bearing formation near the ground, make visibility below 10 kilometers of phenomena, monitor the standard according to environmental quality, PM can usually be stopped outside people's nasal cavity while greater than equalling by particle of 10 micronsing, PM can enter the upper respiratory tract in 2.5 microns - 10 microns, but can discharge outside the body or be stopped by the fine hair within the nasal cavity through the phlegm liquid too, it is difficult to be stopped, will enter bronchus and alveolus directly that PM is smaller than 2.5 microns, initiate asthma, bronchitis, cardiovascular vessel disease,etc.. The haze can be floated over with the wind by other places, can be assembled by the local impurity too. It generally appears under the inversion floor, in the gas-bearing formation near the ground sometimes, in a certain gas-bearing formation of sky sometimes. The density of the haze usually increases with the height, under the inversion floor, visibility is the poorest. There can be several layers of haze in the sky and exist. The relative humidity in the air of haze is generally in under 80%. The haze is sucked from the respiratory tract, will deposit in people's alveolus, enter blood after the smoke and dust which deposits the alveolus is dissolved, damage the ability that hemoglobin transports oxygen, it is apt to cause the blood to be poisoned. Absorb part that dissolve cell apt to destroy cells, lead to the fact pneumoconiosis. Other harmful substances such as sulfur dioxides contained mainly stimulate people's respiratory tract in the haze, more harmful to people. When the haze is serious, its pollutant impurity inside can bring about pathological change in people's nerve centre, cause lung edema or chronic trachitis, especially act as people suck the lung, can cause diseases such as pulmonary emphysema and lung cancer,etc. when being serious. In addition, the chemical smog in the haze, will produce danger to people's skin, eyes, respiratory tract after the density reaches a certain demarcation line. The carbon monoxide in the haze, when its density is 900PPm, people will feel headache, eyes are dull to contact for an hour; When the density reaches 1200PPm, people will contact neural paralysis for an hour, have life dangers. Carbon oxide in the haze, there is strong amazing function on people's eyes, nose and respiratory tract, under certain condition, will produce katogene to the functions of the liver, stomach and heart blood-vascular system. In addition, haze it will also influence people's mood, because the weather is in haze to sink all day, the pale yellow dark of the sun, realizes and secretes out more epiphysin on the pine nut in the human body, make the density of thyroxine, Epinephrine relatively reduce. Thyroxine, Epinephrine,etc. arouses hormone of the cell work, once reduce, cells are known " Lazy " ,Not becoming extremely active, people will seem listless. Go home three the intersection of thing and the intersection of haze and it, we impossible the residence stay indoor at home, can not wrap up all oneself either " Zongzi " ,To some physical training fans, such weather should reduce the outdoor exercises, if do exercises, can choose the trees the more luxuriant place, the happening amount of negative oxygen ion of these places is bigger, the harmfulness should be relatively small. As to some for example extremely attention that hypertension, heart disease, chronic pulmonary tuberculosis, irritation, asthma patient take, adopt the essential shelter, besides wearing the qualified surgical gauze mask of medical use, in fact, the most effective method is how to clear up the haze affixed to our body in time. Director Cao puts emphasis on going home and must do three things: Wash the face, gargle, clear up the nasal cavity, in order to the danger to the human body of preventing the haze. Washing the face had better use the warm water, can clean the haze particle affixed to skin clean effectively; The purpose to gargle is to remove the dirty things attached to oral cavity; The most key one is to clear up the nasal cavity, a lot of people do not know how to clear up, director Cao teaches everybody a simple method apt to study: Behind cleaning both hands, hold the warm water, absorb water gently with the nose and blow one's nose rapidly, repeat for several times, dirty things of the nasal cavity have been all cleaned out. What merits attention is, while clearing up the nasal cavity, must absorb water gently, avoid chocking and coughing. Parents can dip in water with the clean swab, wash repeatedly while clearing up the nasal cavity for children. In the long term, prevent from " the haze is endangered " ,As further doing environmental protection well, reduce the smoke and dust waste gas to pollute, the clean air is imperative. Came down to say from the eyes, when predicting and having or already presenting the haze weather, people should reduce the outdoor sports, especially old and weak and sickly person, must reduce going out, so as not to suck more air pollutants. People should put on the gauze mask while being out, protect well, in order to reduce the danger to the human body of harmful substance in the haze. The tobacco smog is that the environmental group Dahl of one of the indoor air PM2.5 main source asks that the society is (a little rich) to seek knowledge naturally " some inner tobacco smog of restaurant room in Beijing pollutes the situation report " released recently reveals, in the restaurant not having some areas of restaurant and implementation that ban on opium-smoking and the opium trade and stipulate to ban on opium-smoking and the opium trade, PM2.5 density average is about to ban on opium-smoking and the opium trade 2 times of the restaurant in an all-round way. The cigarette, cigar and tobacco pipe will produce a lot of small particulate matters on condition that totally burn, suspend in the air, the harmful substance is affixed to these thin particulate matters. This is principal ingredients of tobacco smog. Most diameters of these particles are only about 1 micron, belong to the category of PM2.5. The tobacco smog contains 7000 multi-type compound, including 69 kinds of carcinogen and 172 kinds of harmful substances. " (Ai Su Zhang XiaoChuan)
