Not the kind it'd like though.
The American Environmental Protection Agency measures air pollution on a 0-500 scale, with 500 being "hazardous." When air pollution gets near 500 the EPA advises people not to go outdoors at all. Edward Wong of the New York Times reported today that Beijing air "quality" as measured by EPA standards at the U.S. Embassy today was...755, which to our understanding translates to "you're dead" and "don't leave your tomb."
