The causes of foggy weather in China

Hello, smog weather forms toxic particles in the city. Source:

The first is automobile exhaust. Large vehicles that use diesel are "recidivists" who emit PM 10, including buses, shuttle buses of various units and large transport trucks. Small cars that use gasoline emit gaseous pollutants, such as nitrogen oxides, which are easily converted into secondary particulate pollutants in foggy days, aggravating smog. PS: At present, the growth rate of motor vehicles in China is obvious to all.

The second is the waste gas produced by burning coal for heating in winter. PS: north.

The third is the waste gas emitted by industrial production. For example, industrial kilns and boilers in metallurgy and electromechanical manufacturing industries, as well as a large amount of waste gas generated by the combustion of automobile repair and painting and building materials production kilns. PS: Although it is being streamlined and closed, it is actually.

The fourth is the dust generated by construction sites and road traffic. It goes without saying that there are enough houses for future generations to live in.

I hope it helps you.
