On October 12, good news came from the Provincial Department of Ecology and Environment: As of October 11 this year, the average concentration of PM2.5 in our province has dropped to 35 micrograms/cubic meter, which is the first time since the monitoring record was found in 2013 that it has reached the national air quality second standard and the first phase target value of WHO , achieving a milestone breakthrough.

Since this year, our province has made improving the ecological environment quality an important area for the welfare of the people, firmly shouldering the political responsibility of energy supply and ecological environment protection, sticking to the goals, and taking innovative measures, focusing on the coordinated governance of ozone in PM2.5 and , and solidly carrying out comprehensive control of air pollution in autumn and winter and ozone pollution in summer, and focusing on in-depth governance of the steel coking industry, clean heating scattered coal clearance project in central Shanxi urban agglomeration, diesel truck pollution and other key areas of air pollution, overcoming the impact of adverse meteorological conditions, and promoting the improvement of environmental air quality in the province to achieve new breakthroughs. In the monitoring data, not only did the average concentration of PM2.5 drop to 35 micrograms/cubic meter, but a number of atmospheric environmental indicators such as the comprehensive environmental air quality index in the province, the average concentration of SO2, the average concentration of PM10, and the average concentration of CO have also continued to improve significantly, setting a new best level in the same period in history, and welcoming the successful convening of the 20th National Congress of the Communist Party of China with outstanding results.

It is reported that my country's PM2.5 standard adopts the maximum margin set by the WHO, that is, the annual average concentration is 35 micrograms/cubic meter. The WHO's guiding value of PM2.5 is 10 micrograms/cubic meter annual concentration, and sets a transitional target for three stages. The first stage is an average annual concentration of 35 micrograms/cubic meter, the second stage is an average annual concentration of 25 micrograms/cubic meter, and the third stage is an average annual concentration of 15 micrograms/cubic meter.
