Is smog related to the weather?

Haze is related to the weather. Different weather will affect the severity of smog. In rainy and windy days, the smog is mild, while in sunny days, the smog is usually more serious.

The main source of smoke:

human factor

(1) Automobile exhaust

(2) Waste gas generated by burning coal for heating in winter in the north.

(3) Waste gas discharged from industrial production. For example, metallurgy, kilns and boilers, electromechanical manufacturing, automobile repair and paint and building materials production produce a lot of waste gas from kiln combustion.

(4) Dust generated by construction sites and road traffic.

(5) The particle size of growth particles, bacteria and viruses is equivalent to PM 0. 1 ~ PM 2.5. When the humidity and temperature in the air are appropriate, microorganisms will attach to particulate matter, especially the particulate matter of oil fume, and the microorganisms will absorb oil droplets and transform them into more microorganisms, which will increase the growth of biotoxic substances in smog.

(6) Dusty home decoration will also produce "smog", and indoor dust will be filled, which will not only be harmful to the health of staff and users, but also increase the cleaning burden. When the dust is serious, it will also bring many hidden dangers to the decoration project.

climatic factor

(1) The phenomenon of static wind in the horizontal direction increases.

(2) There is inversion in the vertical direction.

(3) The increase of suspended particles and organic pollutants in the air. With the growth of urban population and industrial development, the number of motor vehicles has surged, resulting in a large increase in pollutant emissions and suspended solids.
