By contrast, PM2.5 levels averaged 166.6 in 16 airport smoking lounges in the U.S., said a 2012 study by the Centers for Disease Control and Prevention in Atlanta. Levels exceeded 1,000 in Fairbanks, Alaska during a 2004 wildfire that engulfed 6.6 million acres, the state’s website says.

“Unlike cigarette smoking, exposure to ambient air pollution is involuntary and ubiquitously effects entire populations,” C. Arden Pope III, a professor at Brigham Young University who studies the health effects of air pollution, said in an e-mail.

The city’s government this week ordered some cars off its roads, closed factories and recommended that its 20 million residents avoid outdoor activities as air pollution levels hit hazardous for a fifth consecutive day yesterday.
