The best period: Beijing from January to July PM2.5 average concentration of 29 micrograms per cubic meter

Xinhua News Agency, Beijing, August 19 (Reporter Ni Yuanjin) The Beijing Ecological and Environment Bureau released on the 19th that the average PM2.5 concentration of PM2.5 in Beijing was 29 micrograms per cubic meter, a year -on -year decrease of 21.6%. Continue to create the highest history in the same period, with the lowest concentration and the largest decline among the "2+26" cities in Beijing, Tianjin, Hebei and surrounding areas.

In addition, from January to July this year, PM10, nitric oxide, and sulfur dioxide concentration in Beijing were 53 micrograms per cubic meter, 21 micrograms per cubic meter, and 3 micrograms per cubic meter. %, Flat, are the best level in history.

According to the Beijing Ecological and Environment Bureau, since the summer, Beijing has taken nitrogen oxides and volatile organic objects as a breakthrough, strengthened PM2.5 and ozone coordination control, continued to promote green low -carbon transformation and high -quality development, and promoted the "one micrograms" action. Go deep.

In terms of controlling volatile organic matter, Beijing has strengthened source control, accelerated the revision of the standards for air pollutant emissions in the printing and automobile manufacturing industry, further increased the content of the content and management requirements of the content of organic matter, and strengthened process management. The park and agglomeration area complete two-wheeled volatilization organic matter concentrations to take flight monitoring, and establish a closed-loop supervision mechanism for "monitoring-notification-traceability-rectification and improvement".

In terms of promoting nitrogen oxide emission reduction, Beijing promoted the source replacement and actively promoted the new energy vehicle renewal demonstration. Daxing District has accumulated 309 hydrogen energy vehicles. Bus operation. Changping District and Haidian District have carried out demonstration operations of hydrogen energy vehicles, respectively.

According to reports, the next step, Beijing will continue to strengthen the emission reduction of volatile organic matter, nitrogen oxide and other PM2.5 and ozone anterior pre -bodies to promote the continuous improvement of air quality throughout the year.
