Why is the air quality in Changchun poor?

The reasons for the poor air quality in Changchun mainly include the following aspects:

1. industrial pollution: Changchun is an industrial city, and industrial emissions are one of the main causes of air pollution. Pollutants such as waste gas, waste water and waste residue discharged during industrial production will have a serious impact on air quality.

2. Traffic pollution: With the acceleration of urbanization, the number of motor vehicles is increasing, and traffic pollution has become one of the important reasons for the deterioration of air quality in Changchun. Pollutants such as nitrogen oxides and particulate matter in automobile exhaust will have a serious impact on air quality.

3. Weather conditions: Changchun is located in the northeast, with low temperature in winter, stable atmosphere and coal-fired heating, which leads to poor air quality in winter. In addition, weather conditions such as high temperature and high humidity in summer will also lead to the deterioration of air quality.

4. Geographical location: Changchun is located in the northeast, with remote geographical location and inconvenient transportation, which leads to the lagging construction of environmental protection facilities and relatively low awareness of environmental protection, which is also one of the reasons for poor air quality.

In order to improve the air quality in Changchun, the government, enterprises and residents need to work together. The government should strengthen the construction and management of environmental protection facilities, enterprises should strengthen pollution control and emission reduction measures, and residents should raise their awareness of environmental protection and reduce pollutant emissions. At the same time, it is also necessary to strengthen scientific research and explore more effective air pollution control methods.
