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

In order to reduce the smog weather, every resident living in Chengdu should establish the consciousness of "it is everyone's responsibility to resist smog" and take the initiative to become an active participant in improving air quality.

Haze is a combination of fog and haze. Smog is very common in cities. In many areas of China, fog and haze are combined as disastrous weather phenomena for early warning and forecasting, which are collectively called "haze weather". Haze is the result of interaction between specific climatic conditions and human activities. The economic and social activities of high-density population will inevitably emit a large number of fine particles (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particles will continue to accumulate. At this time, if it is affected by calm weather, it is easy to have a wide range of smog.

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. However, in smog weather in different regions, different pollution sources have different functions.

Haze weather has existed since ancient times, and human activities or natural phenomena such as slash-and-burn and volcanic eruption may lead to haze weather. However, after mankind entered the era of fossil fuels, the smog weather really threatened the living environment and health of mankind. Rapid industrialization and urbanization lead to rapid energy consumption, high concentration of population and destruction of ecological environment, which have laid the groundwork for the formation of haze weather.

The formation of smog has both a "source" and an "accomplice", which is a meteorological condition that is not conducive to the spread of pollutants. Once pollutants accumulate for a long time under static meteorological conditions, it is easy to form haze weather. 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.

Some suggestions on controlling smog in life;

1. Everyone should travel by bus or bicycle as much as possible to reduce the travel rate and automobile exhaust emissions.

We should celebrate the Spring Festival in a civilized way. Put less or no fireworks and firecrackers to create a safe, healthy and environmentally friendly Spring Festival.

3. Reform eating habits, resist urban open-air barbecues, and implement a diet structure with low oil smoke, low pollution and low energy consumption.

4. Classified recycling, recycling, do not throw away harmful waste such as discarded batteries, and put garbage in a classified way, so as to recycle resources and benefit mankind.

5. All kinds of greening, fresh air. Put more small potted plants on the balcony at home or in the corridor of the community, which is both beautiful and can purify the air.
