Answer the causes, hazards and measures of haze weather from a geographical perspective

The answer is as follows, remember to accept it

Causes:

First, the emission of pollutants is large. Coal burning, motor vehicles, industry, and dust are all polluting sources with large emissions and are the fundamental causes of serious pollution.

Second, the diffusion conditions are unfavorable. The recent extremely unfavorable pollution diffusion conditions are the direct cause of the pollution process.

Third, the contributions of regional pollution and local pollution are superimposed. Due to the regional nature of PM2.5 pollution and the transmission of associated regional pollution, it is also an important factor in the formation of heavy pollution.

Hazards:

1. Harm to the human body: Because there are a large number of toxic and harmful small particles mixed in the haze, when people breathe, they enter the respiratory tract and lungs with the air. , mild cases will introduce diseases such as tracheitis and pneumonia, and severe cases will lead to more serious diseases.
