What effect does haze weather have on the lungs?

Fog seems mild, but it contains more than 20 kinds of fine particles and toxic substances harmful to human body, including acid, alkali, salt, amine, phenol and so on. , as well as dust, pollen, mites, influenza virus, tuberculosis, pneumococcus and so on. Its content is dozens of times that of ordinary atmospheric water droplets. Haze is more harmful to people's health than fog. Because the diameter of fine powdery floating particles in smog is generally below 0.0 1 micron, they can directly enter bronchi and even lungs through the respiratory system. Therefore, the biggest impact of smog is the human respiratory system, and the diseases caused are mainly concentrated in respiratory diseases, cerebrovascular diseases, nasal inflammation and other diseases. At the same time, in the haze weather, the air pressure decreases, the inhalable particulate matter in the air suddenly increases, the air mobility is poor, and the diffusion speed of harmful bacteria and viruses to the surrounding area slows down, resulting in an increase in the virus concentration in the air and a high risk of disease transmission.
