Research Tracking Beijing's PM2.5 Density Since 2000 Published
Jan 09, 2012 By eChinacities.com

The Beijing Municipal Environmental Protection Bureau recently published the official research tracking Beijing's PM2.5 density over the last decade. The data shows that the city's PM2.5 density has decreased annually; however according to the soon to be published new national standard, 2010's annual average PM2.5 density still exceeds the quota two-fold. In 2000, Beijing's annual average PM2.5 density was 100-110 micrograms per cubic metre. In 2005, that number had decreased to 80-90 micrograms per cubic metre. By 2010, the number further decreased to 70-80 micrograms per cubic metre. According to the soon to be released Ministry of Environmental Protection regulation, called "Ambient Air Quality Standards" (环境空气质量标准), the new quota for annual average PM2.5 density will be capped at 35 micrograms per cubic metre, the same as used by the World Health Organisation. According to this new standard, even though Beijing has seen a reduction in PM2.5 density over the last decade, as of 2010, it still more than doubles the quota.
