Asian Dust (also known as yellow dust, yellow sand, yellow wind or China dust storms) is actually sand from deserts in China and Mongolia that high speed surface winds carry into both North and South Korea during specific periods every year.
The sand particles tend to mix with other toxic substances such as industrial pollutants, as a result of which the ‘yellow dust’ is known to cause a number of respiratory ailments.
Usually, when the dust reaches unhealthy levels in the atmosphere, authorities urge people to remain indoors and limit physical activity, particularly heavy exercise and sport.
