Any suggestions on smog control in Chengdu? Do you have any good ideas?

In order to reduce haze weather, every resident living in Chengdu should establish the awareness that "fighting against haze is everyone's responsibility" and take the initiative to become an active participant in improving air quality.

Haze is a combination of fog and haze. Smog is common in cities. Many areas in China combine fog with haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "haze weather". Smog is the result of the interaction between specific climate conditions and human activities. The economic and social activities of high-density population will inevitably emit large amounts of fine particulate matter (PM 2.5). Once the emissions exceed the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. At this time, if affected by calm weather, it is easy to cause large-scale pollution. Scope of haze.

Smog has various sources, such as vehicle exhaust, industrial emissions, construction dust, garbage burning, and even volcanic eruptions. Smog weather is usually caused by a mixture of multiple pollution sources. However, in haze weather in various regions, the role of different pollution sources varies.

Haze weather has existed since ancient times. Human activities or natural phenomena such as slash-and-burn farming and volcanic eruptions may cause haze weather. However, after humans entered the fossil fuel era, haze weather truly threatened the human living environment and health. Rapid industrialization and urbanization have led to rapid energy consumption, high population concentration, and destruction of the ecological environment, all of which have paved the way for the formation of haze weather.

The formation of haze has both "sources" and "accomplices", which are meteorological conditions that are not conducive to the diffusion of pollutants. Once pollutants accumulate under long-term static meteorological conditions, it is easy to form fog. Haze weather. There are three elements in the formation of haze:

First, the physical source of particulate dust. my country has the largest Loess Plateau area in the world, and its soil texture is most prone to generating granular dust particles.

The second is the dust caused by poor movement. For example, if the mud in the flowerbeds in the middle of the road or on the street curbs flows onto the road after it rains or is splashed with water, it will dry up for an hour and be turned around by the wheels, causing a large amount of dust. Even if these particulate matter falls back to the ground, it will cause dust. Cars kept passing by and were flung over the city again.

The third is that the dust source and movement difference process are concentrated within a certain spatial range, and the particles eventually condense with water molecules to form haze. At present, there are quite abundant stocks of the three elements of haze structure in more than 350 cities in the Loess Plateau region of my country.

Some tips on how to control smog in daily life:

1. When traveling, take buses or ride bicycles as much as possible to reduce vehicle usage and reduce motor vehicle exhaust emissions.

2. We should celebrate the Spring Festival in a civilized manner. Set off less or no fireworks to create a safe, healthy and environmentally friendly Spring Festival.

3. Reform eating habits, resist outdoor barbecues in cities, and implement a diet structure with low oil smoke, low pollution, and low energy consumption.

4. Classify, recycle, and reuse. Do not litter waste batteries and other harmful waste. Classify waste and recycle resources for the benefit of mankind.

5. Various green areas and fresh air. Place more small potted plants on the balcony of your home or in the corridors of your community, which are both beautiful and can purify the air.
