Smog in China

Dense smog has developed in the north of China, across Beijing and Shanghai, i.e. a distance of 1200 km, equivalent to the distance between Kiel (Germany) and Florence (Italy). The smog appears as a brown to grayish area. The concentration of respirable fine particles was 480 micrograms per cubic metre (µg/m³) in Beijing and 355 in Shanghai that day. The WHO limit for fine particles dangerous to health is 25 µg/m³.

 

The white areas are mist or clouds. Under the smog and along the cost there are hints of the sediment influx into the sea caused by the Yellow River and the Yangtze.
