There are many sources of smog, such as automobile exhaust, industrial emissions, building dust, garbage incineration, and even volcanic eruption. Hazy weather is usually formed by the mixed action of various pollution sources. In order to control smog, many provinces and cities around Beijing issued the strictest shutdown order in history. That is to say, from June this year 1 1 to March 20 18, even a few months after the Spring Festival, cities in these areas are not allowed to start all kinds of construction projects.

Extended data:

The formation of smoke has three elements:

The first is the physical basic source of particulate matter. China has the largest loess plateau in the world, and its soil texture is the easiest to produce granular dust particles.

Second, poor exercise leads to dust. For example, the mud in the garden in the middle of the road and the soil on the roadside stones will flow to the road after raining or splashing water, which will produce a lot of dust after one hour of drying. Even if these particles fall back to the ground, they will be thrown over the city again because of the continuous passing of cars.

Thirdly, the basic source of dust and the process of movement difference gather in a certain spatial range, and particles finally gather with water molecules to form haze. At present, in more than 350 cities in the Loess Plateau of China, the three elements of smog structure are quite rich.

Provinces and cities implement the "strictest order":

Not long ago, Shanxi Province issued regulations that the construction unit should take the prevention and control of dust pollution as an important part of signing the contract, include the prevention and control of dust pollution in the project budget and allocate it in time, and fully account for the safety and civilized construction measures.

In June+10, 5438, the smog-prone Beijing issued an emergency plan, stipulating that when a red warning was issued, the construction site would stop earthwork and building demolition, and all vehicles that transport muck, gravel and other dust-prone vehicles would stop driving.

Prior to this, Hebei, a smog-stricken area, also issued "15 Measures for Controlling Dust in Construction in Hebei Province", which is known as "the most stringent order in history".

"Relevant departments to control dust pollution should strengthen cooperation. For example, environmental protection, housing construction, urban management, sanitation and other departments sent representatives to form a joint law enforcement team to inspect all construction sites and solve problems immediately. " Wang, a member of the party group of Taiyuan Environmental Protection Bureau, said.
