The air quality in Beijing poses a “possible risk” to athletes in endurance events, the International Olympic Committee announced today. After analyzing data collected in Beijing in August, the IOC’s medical commission concluded that most competitors won't be affected by the smog, but it will monitor air quality throughout the Games and reschedule events if the pollution is too dangerous, the Washington Post reports.

China has said it would close factories and highways around the time of the games to keep pollution down. (Read more China stories.)
