What are the hazards of smog?

Haze is the result of interaction between specific climatic conditions and human activities. The economic and social activities of high-density population will inevitably emit a large number of fine particles. Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particles will continue to accumulate. At this time, if it is affected by calm weather, it is easy to have a wide range of smog.

Hazards of smoke:

1, which can directly enter and adhere to human respiratory tract and alveoli. In particular, submicron particles will be deposited in the upper and lower respiratory tract and alveoli respectively, causing acute rhinitis and acute bronchitis.

2, the impact on the cardiovascular system, smog weather, there are many pollutants in the air, and low air pressure is easy to induce acute attacks of cardiovascular diseases.

3. Hazy weather will also lead to the weakening of ultraviolet rays in the surface layer, which can enhance the activity of infectious bacteria in the air and increase infectious diseases.

4. It has a certain impact on traffic safety. In foggy weather, the visual visibility is low and the air quality is poor, which is easy to cause traffic jams and traffic accidents.

5. Hazy weather will lead to low air pressure due to weak light, which will affect people's mental health.
