Beijing’s pollution efforts fail
Print Edition
Beijing’s average PM2.5 density last year was more than double the official level targeted nationwide.
Despite the capital’s attempts to limit air pollution, the average PM2.5 reading stood at 85.9 micrograms per cubic meter, 1.45 times more than the national standard, according to “The 2014 Beijing Environment Report” released by the city’s environment watchdog.
With a diameter less than 2.5 micrometers, PM2.5 is the particulate matter that causes hazardous smog.
The report also revealed that the average densities of nitrogen dioxide and PM10 both exceeded standards, although emissions of sulfur dioxide and nitrogen oxide fell by 9.35 percent and 9.24 percent.
Beijing frequently suffers from thick smog, cutting visibility and posing health hazards. Local government measures to try to limit the problem have included restricting traffic and halting industrial production.
