Beijing Air Turns Hazardous as Haze Forecast in Eastern China

Air quality in China’s capital Beijing turned “hazardous” while pollution in Shanghai was rated unhealthy as hazy weather was forecast across parts of the country’s eastern regions.

Concentrations of PM2.5, fine air particulates that pose the greatest health risk, rose to 297 micrograms per cubic meter at 12 p.m. near Tiananmen Square from an average of 195 in the past 24 hours, according to the Beijing Municipal Environmental Monitoring Center. The rating is the second-worst behind “severely polluted.”
