The smog in Chengdu ranks first in the world.

From June 5438 to February 2023, the smog in Chengdu ranked first in the world.

The smog in Chengdu is mainly influenced by topography, climate and environment. Chengdu is located in the basin terrain, surrounded by mountains, with poor air mobility and easy to form smog. In addition, industrial emissions and traffic exhaust emissions in Chengdu are also important causes of smog.

In order to improve the smog problem in Chengdu, the government and all walks of life have taken a series of measures. For example, strengthen the enforcement of environmental laws and regulations, promote clean energy and low-carbon travel modes, and strengthen urban greening. These measures help to reduce the generation and spread of smog and improve air quality. Although the smog problem in Chengdu is serious, people should not be too pessimistic. As long as the government and all walks of life work together and take effective measures, I believe that the air quality in Chengdu will gradually improve.

Analysis of the sources and ways of smog;

1. Industrial emission: The waste gas discharged from the factory contains a lot of particles and harmful gases. If it is not effectively purified, it will be directly discharged into the atmosphere, causing smog.

2. Traffic pollution: Motor vehicle emissions are also one of the main sources of smog, especially particulate emissions from diesel vehicles.

3. Coal pollution: The way of burning coal has become one of the main energy sources in China, but burning coal will release a lot of harmful gases such as sulfur dioxide, nitrogen oxides and particulate matter, which will form smog if directly discharged into the atmosphere.

4. Weather conditions: Weather conditions are also one of the key factors for the formation of smog. Usually, under high pressure and windless weather conditions, meteorological conditions are not conducive to air circulation, resulting in the inability of pollutants in the atmosphere to spread, thus forming smog.
