How to protect health in heavily polluted weather?

During the period from/kloc-0 to 65438+ in October to 65438+ in March, a large-scale heavily polluted weather process occurred in Guanzhong area of our province. Xi' an, Xianyang, Weinan and Xixian have serious and above pollution.

According to the analysis of Shaanxi Environmental Monitoring Center:

The main reasons for the formation of heavy pollution process in Guanzhong area

1, near-surface humidity and cloud cover are large, which is not conducive to the vertical diffusion of pollutants. Affected by the southwest airflow, the near-surface humidity in Guanzhong area gradually increased (about 70% on average), and the sky cloud cover was large, which led to the unfavorable vertical diffusion of pollutants.

2. The wind speed near the ground is small, mainly easterly, which is not conducive to the horizontal diffusion of pollutants. The average wind speed near the ground in Guanzhong area is less than 1.5m/s, which leads to unfavorable horizontal diffusion of pollutants, and the superimposed influence of some imported pollution aggravates the pollution degree.

3. The temperature inversion is obvious day and night, and the height of boundary layer decreases, which leads to the rapid accumulation of pollutants at night and the continuous deterioration of air quality.
