Smog levels spiked in Beijing on Monday, highlighting the environmental challenges facing China as President Xi Jinping arrives in Paris for global climate talks.

The concentration of PM2.5, fine particulates that pose the greatest risk to human health, went “beyond index” in the afternoon, according to a U.S. Embassy monitor. The PM2.5 level was 678 micrograms per cubic meter near Tiananmen Square, the Beijing government said. The World Health Organization recommends average 24-hour exposure to PMI of 25 or below.
