 Good Air Quality Rate of Changchun City up to 89.8% in 2018’s First Two Months

The data released by China National Environmental Monitoring Center show that Changchun enjoyed 53 days of good air quality among the 59 days monitored automatically and effectively for the two first two months of this year, a surge of 16 days year on year, a good ratio of 89.8%, ranking the first among the capital cities in Northeast China. 

The data also show that the concentration of PM10, PM2.5, sulfur dioxide, and nitrogen dioxide is 67 micrograms per cubic meter, 46 micrograms per cubic meter, 43 micrograms per cubic meter and 38 micrograms per cubic meter, a drop of 31.6%, 38.7%, 25.9% and 19.1% year on year, respectively, which all have reached the best level in the same period since the air quality standard was implemented in 2013.

Environmental protection experts and meteorologists say that air quality has become better since the beginning of this year. The air quality was proved good for 21 consecutive days from February 8 to 28 this year. The comprehensive index of air quality on February 20 went up to 38, equal to that of a natural scenic area. The favorable meteorological conditions which were conducive to the diffusion of pollutants were said to have contributed partially to such a good result which was made so mostly due to the air quality treatment countermeasures implemented in recent years.

The CPC Changchun Municipal Committee and the People’s Government of Changchun City have attached great importance to the control and treatment on air pollution in recent years, with improvement in air quality taken as one of the important initiatives for protecting and improving people’s wellbeing, and control of use of coal and reduction of emissions targeted to phase out small coal burning boilers and curb pollution caused by excessive emission of pollutants, vehicle exhausts, dusts and straws. 

In 2017, 1,335 coal burning boilers each of which was below 20 tons, including 1,310 each of which was below 10 tons, were removed, and 10,7213 yellow label vehicles were eliminated, accounting for 96.46% of the total. Twelve coal burning generator sets were upgraded, and nine heavy polluting enterprises were closed or relocated. The rate of mechanization for street and road cleaning in urban districts went up to 85%, which, in turn, reduced dust pollution to a great extent.
