What to do if haze weather continues? What are the dangers of haze weather?

Currently, more than 30,000 pollutant-discharging units in Beijing have implemented emission reduction measures. The Beijing Environmental Monitoring Center predicts that the air quality index in Tongzhou, Miyun, Daxing, Mentougou and Fangshan areas will reach extremely heavy pollution in the next three days. It’s not just Beijing! Monitoring from the Central Meteorological Observatory shows that in the past week, persistent low-visibility haze weather has occurred in most areas of central and eastern my country, affecting public health, transportation, and power grid safety. In fact, continued haze weather and declining air quality are not new phenomena this year. In recent years, every autumn and winter, especially after winter, haze appears in many places. On the surface, the formation of smog has its meteorological factors. From a deeper perspective, the intensification of pollution emissions is the fundamental reason why large-scale smog days are becoming more and more severe. What are the dangers of haze weather? With the deterioration of air quality, the number of haze weather phenomena has increased and the harm has worsened. Recently, many areas in my country have incorporated haze weather phenomena into fog as a disastrous weather warning and forecast. Collectively referred to as "haze weather". In fact, fog and haze are very different from a certain perspective. For example: when fog occurs, the air is humid; when haze occurs, the air is relatively dry, and the relative humidity of the air is usually below 60%. The reason for its formation is the phenomenon of air mixed erosion due to a large number of extremely fine dust particles, smoke particles, salt particles, etc. floating evenly in the air, making the effective horizontal visibility less than 10KM. The symbol is "∞". The diurnal changes in haze are generally not obvious. When there are no major changes in the air mass and the air mass is relatively stable, it will last for a long time, sometimes lasting more than 10 days. Due to weather phenomena such as haze, light fog, sandstorms, blowing sand, floating dust, and smoke, the effective horizontal visibility is less than 10KM due to the influence of a large number of extremely fine dust particles or smoke particles floating in the air. Sometimes it is difficult for meteorological professionals to distinguish. It is necessary to comprehensively analyze and judge factors such as weather background, sky conditions, air humidity, color and smell, and satellite monitoring to draw correct conclusions. Moreover, the weather phenomena of fog and haze can sometimes be converted into each other. Haze is harmful to the human body when inhaled into the human respiratory tract, and can be fatal in severe cases.
