Chemosphere 2021 Sep 14;287(Pt 3):132219. Epub 2021 Sep 14.

Faculty of Geomatics, Lanzhou Jiaotong University, Lanzhou, 730070, China; Gansu Provincial Engineering Laboratory for National Geographic State Monitoring, Lanzhou, 730070, China. Electronic address:

A dust storm that formed in the north of China and the southeastern part of Mongolia in March 2021 significantly deteriorated air quality over a large area of East Asia. According to the synoptic pattern, the cause of the dust storm was a cyclone with a significant drop in pressure leading to high winds and dry components of the soil over parts of the Gobi Desert becoming airborne. Data obtained from ground-based air quality monitoring stations show that the observed hourly PM concentration greatly exceeded the recommended maximum of 150 μg/m with readings above 1500 μg/m in the cities of Tianjin, Baoding, Zhengzhou, Luoyang, Zhoukou.
