Air quality in Chang 'an, Shijiazhuang

On February 8, 2023, the air quality in Chang 'an, Shijiazhuang was heavily polluted.

Good air quality is the basis of maintaining ecological balance and human health. When the air is fresh and pollution-free, we will feel smoother breathing and more energetic. Such an environment helps to improve work efficiency and quality of life.

However, in recent years, due to industrial emissions, traffic exhaust and other reasons, air quality has been gradually threatened. In some cities, the concentration of smog, PM2.5 and other pollutants rises in winter or at a specific time, which has a serious impact on residents' health. This air pollution problem not only harms personal health, but also threatens the balance of the whole ecosystem.

In order to improve air quality, many cities have taken measures, such as limiting industrial emissions, promoting clean energy and raising automobile emission standards. These efforts have achieved results to a certain extent, but the improvement of air quality is not achieved overnight, and it requires the sustained efforts of the whole society.
