QuickTake Choking China

The city’s air was classified as “severely polluted,” the worst level of a 6-grade scale, as the air quality index hit 315 as of 6 a.m., the Shanghai Environmental Monitoring Center said on its website. The concentration of PM2.5 -- particulates considered the must dangerous to people’s health -- was 265 micrograms per cubic meter, the center said. The World Health Organization recommends no more than daily exposures of 25 micrograms.

The air is expected to clear up by the afternoon with light or medium pollution levels forecast, the center said.

The warning followed a red pollution alert by Beijing last week for the first time, that triggered limits on industrial production, bans of outdoor construction and primary school and kindergartens suspensions.
