The influence of smog on life

The harm caused by smog is generally malignant, such as: the air is humid when fog appears; When smog occurs, the air is relatively dry and the relative humidity of the air is usually below 60%. The reason is that a large number of extremely fine dust particles, smoke particles and salt particles float in the air evenly, so that the air with effective horizontal visibility less than 10KM is mixed together. The symbol is "∞". The diurnal variation of haze is generally not obvious. When the air mass changes little and is stable, it lasts for a long time, sometimes exceeding 10 days. Due to weather phenomena such as haze, light fog, sandstorm, sand blowing, floating dust and smoke, the effective horizontal visibility is less than 10KM due to a large number of extremely fine dust particles or smoke particles floating in the air. Sometimes it is difficult for meteorological professionals to tell the difference. It is necessary to comprehensively analyze and judge the weather background, sky conditions, air humidity, color and smell, satellite monitoring and other factors in order to draw a correct conclusion. The weather phenomena of fog and haze can sometimes be converted to each other. Smog is harmful to the human body after being inhaled into the human respiratory tract, and it can be fatal in serious cases.

With the rapid development of society, we have brought destruction to the environment on which we live. What we need to do now is to arouse more people to protect the environment so as not to pose a fatal threat to our next generation! The United States imports Puweixin Tmall
