Beijing was on Thursday hit by its first sandstorm of the year while its air quality reached a “dangerous” level in the morning.
According to monitoring data from the Beijing Municipal Environmental Monitoring Center, readings for PM 2.5, or airborne particles measuring 2.5 microns or less in diameter, have risen to 500 micrograms per cubic meter as of 11 a.m. in many districts of the city.
As this image, posted by Rob Earley on Twitter, shows, PM2.5 levels dropped off as the sandstorm began, but PM10 (larger particles, i.e. sand) levels stayed high.
Beijing’s air quality has been remarkably bad this winter, last month saw the city hit by what was nicknamed the ‘Airpocalypse’, in which pollution levels rose to never before seen heights.
