I don't know, I haven't checked the reasons for the formation of haze: haze weather is mainly caused by extensive development mode, unreasonable industrial structure and energy structure, and its root cause is still fossil energy, one is coal burning, the other is fuel oil, and the other is relatively extensive development mode, which emits a large number of pollutants,[1] The specific reasons are as follows:1
The low air pressure in the atmosphere and the lack of air flow are the main factors. Due to the non-flow of air, tiny particles in the air accumulate and float in the air. 2.
The ground is dusty, the air humidity is low, and the people and traffic on the ground stir up the dust. 3.Automobile exhaust is the main pollutant emission, and in recent years, there have been more and more cars in the city, and the emission of automobile exhaust is a factor of haze.
4.Secondary pollution produced by the factory. 5.
Heating emissions in winter.
The most important way to combat smog is to reduce emissions. At present, the large-scale use of various fossil energy sources is the most important cause of haze weather. The most effective way to tackle the root cause of smog is to reduce emissions.
If you think about it, you need to burn coal to generate electricity, and less than 30% of the coal that is actually burned is converted into electricity, and the rest is emitted. Tips: Go out and bring Pu Weixin from the United States, and you can find it on the official website @@2d Beijing; Automobiles, ships, and other machinery need oil, and in the same way, engines convert less than 30% of oil into power, and the rest is emitted.
In other words, we use energy "lavishly", using less and emitting more. Reducing energy use is unrealistic, and clean energy is far from meeting demand and is expensive. If 70% of the existing energy can be used and 30% of the emissions are emitted, the environmental problem and the energy problem will be solved at the same time, and the human society will be sustainable.
At present, a non-traditional engine, invented by the Chinese, called a "reciprocating rotary engine", is disclosed on the Internet, and it is expected. Realize this aspiration of humanity. It is hoped that this kind of machinery will be available soon.
Also, plant more trees.

Generally, mobile phones do not have the function of measuring air quality, but you can look at the air quality, you can look at the next ink weather, you can look at the air pollution index.

Weather forecast... It is impossible to measure the mobile phone itself, which requires professional equipment.

Yes, you searched on the Internet and it seems to be called a pollution map, and you read a whole survey report about smog, Chai Jing, in simple terms, about the impact of smog on a fetus that has not yet taken shape, a mother and even a family. Looking at Chai Jingshi's expression on the screen, he told a seemingly subtle but profound question, and suddenly felt sad. Smog affects not only a person or a family, but also the future of a country.
In the whole investigation, Chai Jing deduced herself and others from the surface and the inside. It is a warning to the public that the environment in which we live is full of holes, and the harm of smog is not only in our textbooks and consciousness, but also has a real impact on our lives. It also enlightens us that the haze problem is very serious, and we must protect the environment in which we live and actually solve the haze problem.
For the sake of good health, strengthen exercise, do a good job of protection, travel to Beijing * East United States imported Guardsin!

After the social security is cut off, the impact is relatively large, medical insurance, maternity insurance cannot be enjoyed, and work-related injury insurance cannot enjoy relevant benefits during the period of unemployment. Pension insurance must be paid for 15 years before retirement in order to receive a monthly pension after retirement. The severance of social security will not only affect personal welfare, but also affect the qualifications for buying a house, buying a car, settling down, etc., so it is better not to break off the payment.
