1. The main factor when the atmospheric pressure is low and the air does not flow. Because the air does not flow, the tiny particles in the air gather together and float in the air.
2. The ground is dusty and the air humidity is low. People and vehicles on the ground stir up dust.
3. Automobile exhaust is the main pollutant emission. In recent years, there are more and more cars in cities, and automobile exhaust is a factor of smog.
4. Secondary pollution produced by factories.
5. CO2 and other pollutants emitted by heating in winter.
Minimize going out in foggy days. If you travel, you should be well protected. On this day, Puweixin, a cat imported from America, will help you reduce smog inhalation.
There is no good way to control smog at present.
The sources of Haze Village are mainly coal-fired power plants, steel mills and chemical plants. Although the media mainly focuses on cars, in fact, this is mainly because cars are better managed. At present, the implementation of automobile number limit has basically achieved all the measures that can be taken in this regard. In the deepening, cars can only be banned. Unfortunately, even if the car is banned, it is useless, and the smog will still come. Because you can't stop generating electricity, can you? All the factories are closed?
The only feasible way is to control pollution emissions and strengthen investment in environmental protection measures. However, this will inevitably further increase the burden on enterprises. Now the profits of domestic industrial entities have basically been exploited to the extreme edge of the cliff. It is likely that a loss of profit of only one percentage point will probably lead to the collapse of the entire industrial base. This is a disaster ten million times worse than the legendary financial crisis. It will take some time to adjust the interests of the social industry, which will affect the whole body, so these things can only be done slowly.
