Shanghai's concentration of tiny, harmful PM 2.5 particles reached 602.5 micrograms per cubic meter Friday afternoon, an extremely hazardous level that was the highest since the city began recording such data last December.

Beijing, the capital, has seen extremely heavy smog several times over the past year. In the far northeastern city of Harbin, some monitoring sites reported PM 2.5 rates up to 1,000 micrograms per cubic meter in October, when the winter heating season kicked off.
