In the first half of the year, the national ecological environment quality status | The general improvement of air quality in the country has stable and stable.

The Ministry of Ecology and Environment recently reported the national ecological environment quality status from January to June this year. Data show that in the first half of this year, the national air quality improved overall, and the proportion of excellent days in cities and above in the country reached 84.6%, an increase of 0.3 percentage points year -on -year. Let's take a look at the interpretation of air and environmental quality data in the first half of this year.

According to the latest monitoring, in the first half of this year, the national air quality improved overall. The average number of excellent air quality in 339 prefecture -level and above cities reached 84.6%, a year -on -year increase of 0.3 percentage points. Fall 5.9%; the average PM10 concentration was 55 micrograms/cubic meter, a year -on -year decrease of 8.3%; the average concentration of SO2 was 9 micrograms/cubic meter, a year -on -year decrease of 10.0%; The average concentration was 1.1 mg/cubic meter, a year -on -year decrease of 8.3%. The average concentration of O3 was 144 micrograms/cubic meters, an increase of 4.3%year -on -year.

Tang Guigang, director of the Atmospheric Environment Monitoring Office of China Environmental Monitoring Station: If a word is used to describe the improvement of air quality in the first half of 2022, I think the word "steady and advanced" can be used. In the first half of the year, 6 indicators of air quality nationwide showed five drops and one liter. From the trend in recent years, the change was generally relatively stable.

Experts believe that the most obvious areas of air quality in recent years are the "2+26" cities in Beijing, Tianjin, Hebei and surrounding areas. The average PM2.5 average concentration has decreased by 38.2%compared with 2017. In 2017, 67.6%and 59.4%were decreased, and these three indicators showed that the regional coal -fired governance was significantly effective.
