Shanghai warned children and the elderly to stay indoors as the level of the most harmful pollutants exceeded more than 10 times the level deemed safe by the World Health Organization.
The air pollution index in the nation’s commercial hub exceeded 300 as of 1:41 p.m., placing it in the “severe” range and the highest of six levels, the Shanghai Environmental Monitoring Center said on its website today. PM2.5 pollutants -- particles smaller than 2.5 microns in diameter that pose the biggest health risk -- reached 288.9, more than 10 times the WHO threshold, before falling to 211.5.
