Talk about why the government should control smog

The reason why the government controls smog is because smog weather has the following hazards:

1, affecting health. Living in smog weather will cause adverse reactions such as cough, dizziness and fatigue, while inhalable particles can directly enter the human respiratory tract and lungs to induce diseases. Hazy weather will also weaken the ultraviolet radiation near the surface layer, which will easily increase the activity of infectious bacteria in the air and lead to an increase in infectious diseases.

2. Acid rain has formed. The essence of smog is "fine particle pollution", which mainly comes from the pollution of PM2.5 by gases such as industrial waste gas and automobile exhaust. The research shows that there is little water content in the smog components, but there are many acid fogs formed by waste gas pollutants such as sulfuric acid, sulfur dioxide and nitrogen dioxide, and the concentrations of soluble and insoluble pollutants are high.

3. Agricultural production reduction. Hazy weather also has a negative impact on agriculture. Studies have shown that serious pollution will affect solar radiation, which is not conducive to the absorption of sunlight by crops, resulting in crop yield reduction as high as 25%.

4, cause an accident. When smog weather occurs, the air quality is poor and the visibility of the site is low, which is easy to cause traffic jams and then traffic accidents.
