At least 24 cities across China have issued heavy smog alerts on Friday as the country suffers from the worst air pollution levels in months.
Environmental authorities in Beijing issued a red alert for severe air pollution after smog levels in the capital spiked on Friday.
By Saturday afternoon, PM2.5 density exceeded 300 in central Beijing – six times the standards set by the World Health Organization - the Beijing Municipal Environmental Monitoring Center reported.
Other cities have since issued alerts of different degrees: residents in the metropolises of Tianjin and Zhengzhou saw red alerts, while a yellow alert was issued in Harbin, Heilongjiang Province.
A cold front set to hit the capital Wednesday night will disperse the smog, meteorologists said.
