Haze is a kind of freak?

Since 2013, Beijing has appeared very serious haze weather, PM2.5 exceeded by more than four times that many people cough, cold, able to come up gas, or even killed, especially the elderly, heavy harm. Circumstances worse than ever, the world was shocked.
However, many people do not understand the "haze" is how the matter. Even the word "haze" looked unfamiliar, do not know, the concept does not come out, but do not understand that it is a monster, research competing it and said before the "fog" and "Sandstorm" is not the same thing, of course, , it is not clear, it is the source of what is, and how to govern it.
On the morning of January 18, the CPC Central Committee and the State Council held a national science and technology awards, including a research project won the National Natural Science Award, the winners of the Zhuang Professor of the College of Environmental Sciences, Fudan University in Shanghai, he and his research group spent time in more than a decade of the "haze" monster, and come to a clear conclusion, to figure out how the haze is formed, from where.
This award was too timely, flatter.
I cheer for this award-winning, and that all Chinese people should be grateful to Professor Zhuang and his research group, their right direction, which can be called scientific research truly social services, combining Now that the actual science and society.
In fact, the haze is not fog, sandstorms.
No haze in my childhood, it is with the changes in the economic development and historical product, is the last ten years in Beijing, Shanghai and other major cities as well as the last five years and appeared in small towns.
Culprit, almost only one, is the car!
Haze is a high concentration of fine particles of very small diameter, 2.5 microns or less, can be drawn directly into the deep lung harm people's health. Concentrations of 50-70 micrograms per cubic meter, while the formation of haze. The weather in Beijing, almost a decade ago, has already reached 150 days a year.
In recent decades, more than 250 days.
In other words, we Beijingers have more than 70% of the time living in a dirty haze.
Extremely horrible!
Ten years ago, I was standing in a sunny day when Looking to the Beijing Xishan ridge, I was immediately terrified. Look East, simply can not see Beijing, Beijing entire child buckle under a gray lid. That we were breathing in the thick opaque dark dirty lid inside all day, life, no possession did not hide, but regardless of the high or low level, should be equal, full suck this odor! Too bad. While at the same time from the ridge to the west to see, actually I looked a thousand miles, matter to fresh opacity. The mountain across, completely two different worlds.
So I knew early on that the haze harm to Beijing, and know that the situation is extremely serious.
But I do not know that the haze in the end comes from where.
This time, the Professor looked Zhuang, I only know haze formed in the exhaust of the car with. The fine particles in urban air by nitrate 塩 and sulfuric Salt. The nitrate 塩 mainly from automobile exhaust, the sulfate 塩 from industrial emissions and automobile exhaust. Ten years ago, the proportion of nitrate Salt and sulfuric acid Salt is 3:7, 1:1, that the amount of car exhaust and factory emissions.
The conclusion is clear: You can not rely on nature. Nature, not windy and humidity, the surge in the concentration of fine particles and the formation of haze days, but they can only external factors; excessive depends only depends automobile Development. Absolutely should limit the total city car exist. Any measures of governance haze must take this as a starting point, including strictly regulate auto emissions standards, and gradually replaced with rail transit cars, to improve the quality of gasoline, and the implementation of more stringent policy purchase, Bus stricter control provisions In short, absolutely no longer encourage the production of cars and the use of cars! governance haze can only be evasive, or intentionally dumb, harm to victims has.
I wrote a small article entitled "Road to Paris", said the three lanes of the city of Paris, only a car leaving a driveway, unlike us, in order to encourage a car desperately expanding road and three is not enough to build four Road, and then not enough to build five. Estimated Regardless of the specific approach of the Paris car limit study competition how should see, they already have a new idea, is absolutely a permanent cure ideas to limit production of the car, and that is fundamentally no longer encourage the use of cars. This is the rule haze the right way.
