Highest Level of Yellow Dust in Four Years Hits Seoul

It is going to be interesting to learn in the future if all this yellow dust is going to have adverse health affects on Koreans:

Seoul was hit by a record-high level of ultrafine dust, known as a class one carcinogen, on Monday, as most of South Korea was blanketed by extraordinarily heavy levels of choking dust particles for the fourth consecutive day.
The Ministry of Environment has decided to extend a set of emergency measures aimed at reducing fine dust in Seoul, Incheon and Gyeonggi Province through Tuesday. It would be the first time for the government to implement the system in the metropolitan area, which has around 20 million residents, for three consecutive days.
Under the step, vehicles with license plates ending in even numbers and used by public offices, will be restricted from operating on Tuesday. And the operation of 2.5-ton diesel cars or bigger ones, registered with metropolitan governments before 2005, will be limited.
The daily average level of ultrafine particles, smaller than 2.5 micrometers in diameter, in Seoul surged to 118 micrograms per cubic meter as of 3 p.m., the highest figure since the government began taking such measurements in 2015, according to the state-run National Institute of Environmental Research.
