Seven days of heavy air pollution were recorded, said the capital's Municipal Ecology and Environment Bureau.

The cumulative concentration of PM2.5 in Q1 was 52 micrograms per cubic meter, remaining flat compared with the same period last year, while the cumulative concentrations of Beijing's other three major air pollutants including PM10 dropped more than 20 percent year on year.

The average concentration of PM2.5 from October 2019 to March 2020 was 47 micrograms per cubic meter, falling 9.6 percent year on year, according to the bureau.

To continuously improve the city's air quality, Beijing has taken a series of measures such as speeding up the phasing out of heavy diesel vehicles and building more online video monitoring systems for observing dust at construction sites.
