The air pollution level this morning reached 251 on a scale of 300 in Beijing—and even higher, 278, in Shanghai. While 51-100 on the Air Pollution Index Scale is “good,” with no health implications, the air quality in China today is so poor that even healthy people will be noticeably affected; and will have trouble breathing and walking outside.
Air quality was even worse over the past weekend. Emergency response measures were adopted in Beijing when the city's air quality reached a level of 755, regarded as "beyond index." For the first time, Beijing activated a new plan restricting construction and industrial activity, curbing vehicle use by government officials and ordering schools to limit outside activity, said state-run Xinhua news agency.
