Beijing’s air quality continues to improve
Print Edition
BEIJING’S air quality in the first six months of the year improved significantly, according to the city’s environmental protection bureau.
The concentration of PM2.5, airborne particles measuring less than 2.5 microns, which are small enough to enter the bloodstream, fell 15 percent from the equivalent period of last year to 77.7 micrograms per cubic meter, it said on Thursday.
The densities of sulfur dioxide, nitrogen dioxide and PM10 dropped by 41 percent, 14.5 percent and 13 percent, respectively.
The bureau claimed there were 88 days of sound air quality, nine days more than the same period of last year, while air pollution was registered on only 16 days, down from 25 last year.
“Conditions were favorable in the first half of the year, but not enough that there was a sharp reduction in air pollution,” said Sun Feng with the bureau’s monitoring center.
Limits on emissions and clean production in Beijing and its surrounding areas had helped to improve air quality, he said.
Last year, Beijing reduced coal consumption by 2.8 million tons. In March, two coal power plants were shut down, while 200,000 heavy polluting vehicles and more than 300 polluting factories will be phased out this year.
As part of its bid to host the 2022 Winter Olympic Games, Beijing has vowed to cut its PM2.5 density by 20 percent by 2017, backed by government funding of US$130 billion.
