Hazy weather in Jiangsu

Many highways in Jiangsu are closed due to smog. How harmful is smog to human body?

1. How did the smog come from? Haze is a common phenomenon in autumn and winter. Due to smog, many roads have to be blocked, mainly for people's safety, because people's travel will also be damaged in smog weather. Therefore, for everyone's safety, closing multiple roads can reduce the occurrence of traffic accidents to a certain extent. Haze is a kind of weather pollution phenomenon, because more and more pollutants are gathered in the air. In addition, the weather is very stable, and these smog are difficult to spread, so they stay in the air for a long time. So in autumn and winter, you can often see the foggy sky. In fact, this is smog, which is a kind of pollutant, because some particles produced by our human production and living activities are suspended in the air.

Second, what is the harm of smog? After the smog is produced, it will be suspended in the air for a long time because it cannot spread in a short time, which will do some harm to people's health, and some people will have respiratory diseases. Therefore, every autumn and winter, there will be more and more people suffering from respiratory diseases in hospitals, and some people will get sick because of smog. Smog also has a very big impact, that is, it will affect the driver's line of sight, so some highways will be temporarily closed. It is because the speed on the expressway is very fast, and if the smog is serious, it is likely to lead to traffic accidents, so the influence of smog on human beings is very great.

Third, what should I pay attention to in foggy days? When there is foggy weather, it is not recommended to go out because of the poor air quality. If you have to go out, you must do personal protection. Wearing a proper mask can prevent smog from entering our bodies. Secondly, after walking outside, you must take off your coat and clean it when you go home, because smog will attach to people's clothes, so try not to open the window for ventilation in foggy days. Because pollutants will flow into the room with the air, it is difficult to be discharged outside. Secondly, people who go out must pay attention to traffic safety, because smog, like the fog we usually see, will seriously affect people's sight, so everyone must pay attention to prevention in foggy days and don't accidentally lead to adverse consequences.
