November 7, China's winter solstice, winter quietly came. The temperature of the weather has
dropped and people's clothes are increasing. With the cold weather, Shijiazhuang haze has gradually
appeared in people's eyes.
Footsteps hurry in the fog enveloped the huge cage, the busy road full of car Ming, turbid air is
impetuous flavor. Haze, is also the soul of the gloomy, desire congestion.
Haze, as the name suggests is a fog and haze. Fog is an aerosol system consisting of a large number
of tiny water droplets or ice crystals suspended in near-surface air. Haze, also known as haze
(smoke) dust in the air, sulfuric acid, nitric acid, organic hydrocarbons and other particles can
also make the atmosphere turbid.
Haze is an atmospheric pollution state, haze is a variety of suspended particulate matter in the
atmosphere exceeded the general expression, especially PM2.5 (aerodynamic equivalent diameter less
than or equal to 2.5 micron particles) is considered to be caused by haze The "culprit" of the
weather. With the deterioration of air quality, haze weather phenomenon increased, increasing the
harm. Many regions in China combined haze weather phenomena into the fog as a severe weather
warning and forecast.
Haze on human health hazards. Since particulate haze of small particles of 0.01 microns in diameter
or less general diameter, you can go directly through the bronchial respiratory system, or even
the lungs. Therefore, the greatest impact of haze is the human respiratory system, causing diseases
mainly in respiratory diseases, cerebrovascular disease, nasal inflammation and other diseases.
At the same time, the haze weather, air pressure, air inhalable particulate matter, air mobility
is poor, harmful bacteria and viruses spread to the surrounding slow down, resulting in increased
airborne virus concentration, the risk of disease transmission is high.
Shijiazhuang government to take the line, close the factory and other measures, people who travel
to bring the anti-fog haze masks, if you come to Shijiazhuang to visit our factory, please keep
