(Bloomberg) — Shanghai issued a warning for children and the elderly to stay indoors as air pollution levels in the city rose to “heavy,” mirroring a red alert for smog issued by Beijing that’s prompted school closures.
The concentration of PM2.5 — particles considered the must dangerous to people’s health — rose to as high as 156 micrograms per cubic meter at 6 a.m. in Shanghai. It was 170 at 7 a.m. near Beijing’s Tiananmen Square, the municipal monitoring center said. The World Health Organization recommends daily exposure of no more than 25 micrograms.
In addition to the health warning, Shanghai also initiated a series of “winter pollution” measures at 7 a.m. that halted construction and demolition work in central areas of the city, according to the municipal government’s official microblog.
Beijing’s red alert warning, the second this month, was issued last week and runs through tomorrow. In addition to shutting schools, the warning also includes traffic restrictions and limits on factories production.
