Beijing sees best air quality in first eight months
The average PM2.5 density in the city was 18 micrograms per cubic meter in August, also a record low, according to the municipal ecology and environment bureau.
The Chinese capital reported 29 days of good air quality in August, or 93.5 percent of the month, the bureau said.
Beijing authorities have taken a slew of measures to tackle air pollution, including promoting new energy cars and monitoring diesel vehicles.
PM2.5 airborne particles smaller than 2.5 micrometers in diameter pose serious health risks. ■
