Beijing suffered its worst air pollution of the year on Mon. 30th, with monitoring sites throughout the city reporting extremely hazardous levels of pollutants.
City authorities issued a rare orange alert, the second highest of four danger levels. Schools suspended outdoor activities and polluting factories were required to reduce production.
Visibility was cut to several hundred meters (yards), as buildings receded into thick smog. People complained of a smoky, pungent odor, and many wore tight-fitting face masks.
