China Pollution Tops Hazardous Levels Ahead of Congress

Pollution in Beijing was stuck at unhealthy levels for the seventh straight day, prompting warnings for people to stay indoors as thick gray smog shrouded the capital a week before the annual meeting of China’s legislature.

The concentration of PM2.5, the small particles that pose the greatest risk to human health, hit 512 at 10 a.m. today, or “beyond index,” according to a U.S. Embassy pollution monitor. The World Health Organization recommends day-long exposure levels of 25, and the last time PM2.5 dropped below 150 in Beijing was Feb. 19.
