Super smog in northern Chinese city closes schools, cancels flight and halts buses
Visibility shrank to less than half a football field and small-particle pollution soared to a record 40 times higher than an international safety standard in one northern Chinese city as the region entered its high-smog season.
The manager for U.S. jazz singer Patti Austin, meanwhile, said the singer had cancelled a concert in Beijing because of an asthma attack likely linked to pollution.
Winter typically brings the worst air pollution to northern China because of a combination of weather conditions and an increase in the burning of coal for homes and municipal heating systems, which usually starts on a specific date. For the large northern city of Harbin, the city’s heating systems kicked in on Sunday, and on Monday visibility there was less than 50 metres, according to state media. (AP/AFP Photos)
