The weather forecast says that there will be mild to moderate haze in Beijing, Tianjin, Hebei and its surrounding areas. What do you think smog is?

According to the weather forecast, due to the deterioration of atmospheric diffusion conditions in Beijing, Tianjin and Hebei and surrounding areas, it will cause mild to moderate haze, but after that, it will weaken or disappear due to the influence of cold air. Haze and fog are two completely different weather conditions. Some people often associate smog and call this kind of weather foggy. So what is smog? It refers to some uncertain reasons, such as toxic and harmful gases emitted by factories and automobile exhaust, which lead to air pollution. These pollutants contain a lot of particles suspended in the air, which cannot be purified, resulting in smog. Haze is poisonous and harmful. Long-term inhalation will enter the respiratory system such as the lungs, causing diseases of various systems in the whole body and having certain effects on various organs. It can be seen that the influence of smog is not generally great. In China, due to the development of the city itself, many areas in Beijing, Tianjin, Hebei, Shandong, Henan and other places will be affected by smog. In recent years, the living environment and conditions have been greatly improved due to continuous treatment. So what preparations should I make when I go out on a foggy day?

1 Wear a mask. It is best to wear a mask before going out, which can not only prevent the inhalation of smog, but also keep warm. To choose some masks with good protective performance, it is best to choose professional masks with air valves. Wearing a mask can also prevent the virus from spreading in public places. After use, the mask should be discarded in a special recycling box, and it is not allowed to be placed at will.

② Pay attention to driving safety. Hazy weather will affect the driving sight, especially when driving. Turn on fog lights, wear a helmet when driving a battery car, always pay attention to passing vehicles and speed when crossing the road and moving forward, and brake in time in case of danger.

Eat more foods that moisten the lungs. Pay attention to drink plenty of water at ordinary times. Pay attention to eating some foods that moisten the lungs, such as pears and radishes, to avoid the duration of outdoor activities.

In short, you should pay more attention at ordinary times. In foggy weather, try to hide indoors and turn on the air purifier.
