Pollution in China  NOV 05 2009

How bad is the pollution in China? James Fallows reports.

The Chinese government does not report, and may not even measure, what other countries consider the most dangerous form of air pollution: PM2.5, the smallest particulate matter, tiny enough to work its way deep into the alveoli. Instead, Chinese reports cover only the grosser PM10 particulates, which are less dangerous but more unsightly, because they make the air dark and turn your handkerchief black if you blow your nose. (Spitting on the street: routine in China. Blowing your nose into a handkerchief: something no cultured person would do.) These unauthorized PM2.5 readings, sent out on a Twitter stream (BeijingAir), show the pollution in Beijing routinely to be in the "Very Unhealthy" or "Hazardous" range, not seen in U.S. cities in decades. I've heard from friends about persistent coughs and blood tests that show traces of heavy metals. "I encourage people with children not to consider extended tours in China," a Western-trained doctor said. "Those little lungs."

Update: Here are some pretty compelling photos of Chinese pollution. (thx, kurt)

Update: Stephen Voss has a set of Chinese pollution photos along with an accompanying story.
