Beijing’s air pollution reached eight times World Health Organization-recommended levels as smog in the city persisted for a fourth day, prompting China’s environmental protection regulator to send inspection teams to the capital and surrounding areas.
The concentration of PM2.5, fine particulates that pose the greatest risk to human health, was 198 micrograms per cubic meter near the Tiananmen Square in China’s capital at 11 a.m, the Beijing Municipal Environmental Monitoring Center said on its website. The WHO recommends levels of no higher than 25 micrograms per cubic meter in 24 hours.
