BEIJING - Beijing began disclosing the amount of tiny pollution particles in the air on Saturday, in a move that could improve disclosure but alarm a public barely resigned to the capital's choking smog.
The new measurement of particles of 2.5 micrometers or less in diameter, or PM2.5, comes after growing attention to air quality in Beijing, one of the world's most heavily polluted capitals, from Chinese as well as foreigners."So that the people can form a relatively complete understanding of the Beijing air quality, the Beijing Municipal Environmental Monitoring Center will publish hourly 2.5 data from Jan. 21," the center said on its website.
