Where is the most serious smog in the second half of the year?

In recent years, every winter, people are troubled by the smog problem, and it is getting worse every year. Recently, the meteorological department speculated that this year's severe smog period came again, mainly in North China, and many of them were due to topography.

Speaking of smog, although it can't be said, it is also very worrying. It has three main components, among which inhalable particles will bring great harm to human body.

Inhalation of particles in smog into the lungs will first affect the normal operation of lung function, followed by the problem that people are easily infected by bacteria and have low immunity, which may also lead to cardiovascular and cerebrovascular diseases and have an impact on children's intellectual development. Therefore, if smog can't be treated and left unchecked for a long time, it will definitely bring serious consequences.

So how did the smog come from? Research shows that the main reason is automobile exhaust. With the increasing frequency of automobile driving, more and more exhaust gas is discharged, which produces a large number of pollutants, which is also related to coal burning in North China and other regions, as well as the topography of North China and other regions.

With the smog problem becoming more and more serious, the state has taken many measures. Because of the great influence of automobile exhaust, from the root, it is necessary to limit automobiles, reduce exhaust emissions from fuel vehicles, encourage people to travel by bike, and alleviate traffic pressure. At the same time, it is also necessary to ban the burning of coal in some areas and encourage the development of new energy vehicles, so that there will be no exhaust emissions of a large number of pollutants and energy can be saved. These are some measures taken at present, but we need to reach an agreement.

In foggy days, you must take precautions. First of all, because of the severe smog in the morning, try not to go out in the morning and don't exercise in foggy days. If you go out, you must wear a mask and install an air purifier at home to facilitate ventilation and prevent pollutants from coming in.

With the smog problem becoming more and more serious, people pay more and more attention to this problem, so we should do our best to do our part to control smog.
