The average PM2.5 density in Beijing stood at 34 micrograms per cubic meter of air from January to August this year, the lowest for the period on record, authorities said last Sunday.

PM2.5 means airborne particles smaller than 2.5 micrometers in diameter, which pose serious health risks.

The Chinese capital reported 29 days of good air quality in August, or 93.5 percent of the month, the authorities said.

Beijing has taken a slew of measures to tackle air pollution, including promoting new-energy cars and monitoring diesel-run vehicles.
