Air quality worsens as sandstorm hits Beijing

Beijing:  The second sandstorm in two weeks hit Beijing on Sunday, turning the skyline yellow and plunging air quality readings to severely polluted.

The Chinese capital experienced strong winds on Sunday morning and visibility reduced to between 1 km and 2 km in most areas, according to Beijing’s meteorological service.

Zhang Linna, chief forecaster at the municipal meteorological station, said the dusty weather, featuring strong winds and thick dust, will last more than 12 hours but its intensity will be slightly weaker than the sandstorm seen on March 15, reports Xinhua news agency.

The Beijing Municipal Ecological and Environmental Monitoring Center said the sandstorm was blown southward into China after striking Mongolia between Friday and Saturday.

The sandstorm had already shrouded the entire city of Beijing by 7 a.m. on Sunday, with the PM 10 concentration surpassing 2,000 micrograms per cubic meter, according to the center.

It predicted that the air pollution will alleviate on Sunday evening as the sandstorm subsides.

Official data shows Beijing’s sandstorm onslaughts peaked in the 1950s, when it recorded an average of 18 dusty days a year, but later subsided as afforestation in northern China picked up steam.

In the first decade of the new century, the city logged an average of 0.6 dusty days per year.

Dusty weather was also observed in other parts of northern and northwestern China, including the Inner Mongolia Autonomous Region and the provinces of Gansu, Shanxi and Hebei.

Seven of the 11 cities in Shanxi province hit the highest possible reading in the air quality index (AQI) on Sunday morning — 500, which suggests hazardous air pollution, with PM 10 being the primary pollutant.
