From the WSJ:
According to the government monitoring, levels of PM2.5 particles were above 700 micrograms per cubic meter on Saturday, and declined by Monday to levels around 350 micrograms — but still way above the World Health Organization's safety levels of 25.
In separate monitoring by the U.S. Embassy, levels peaked Saturday at 886 micrograms — and the air quality was labeled as "beyond index."
