Shanghai PM2.5 density nearly 4 times China limit, paper says

Shanghai experienced this autumn’s first heavily polluted day on Thursday with the PM2.5 density nearly four times the national limit, Shanghai Daily reported. The reading for the airborne particulates with diameter of 2.5 micrometers or less rose to a hazardous level of 240 micrograms per cubic meter in the morning, dropped to 160 by late afternoon but soared again in the evening, enveloping most of the city in a haze. It peaked at 270 around 8pm, nearly four times the national limit of 75, the report said.
