The level of pollutants is 37 times greater than the daily average value of 45 micrograms per m2
A severe sandstorm is “sweeping” Beijing, which has been covered in a thick cloud of dust, pushing air pollution to dangerous levels, as announced by the state meteorological service.
According to CNN, authorities warned citizens not to go out for exercise and other activities, while they called on drivers to be especially careful and to move at low speeds, due to limited visibility.

It is characteristic that at six in the morning – local time – the concentrations of PM10 particles reached 1,667 micrograms per cubic meter, levels that make “the sandstorm the most severe that has occurred in 2023”. This level of pollutants is 37 times greater than the daily average value of 45 micrograms per square meter defined as acceptable by the World Health Organization.
Sandstorms are quite common in Beijing especially in Spring.
Nearly a dozen provinces issued yellow warning signals from Wednesday to early Thursday morning, according to the China Meteorological Administration.
