Beijing Pollution beyond Index Readings Print E-mail

Account Pollution.jpgBEIJING: Pollution in Beijing has become so terrible that scientists are unable to measure air quality anymore. Accordingly, many Beijingers refused to go outside, while the city's skyline disappeared in a murky haze.

The Houston Chronicle reports that, "the Beijing Municipal Environmental Monitoring Center said on its website that the density of PM2.5 particulates had surpassed 700 micrograms per cubic meter in many parts of the city. The World Health Organization considers a safe daily level to be 25 micrograms per cubic meter."

PM2.5 are tiny matter that is less than 2.5 micrometers in size, or approximately 1/30th the average width of human hair, which could penetrate deep into the lungs. Hence, measuring them would be deemed a more accurate reflection of air quality as opposed to other methods.

According to the Houston Chronicle, "the Beijing Center recommended that children and the elderly stay indoors, and that others avoid outdoor activities."

Nonetheless, Beijing streets remained crowded on Sunday, according to a first-hand account.
