yellow dust has always existed. people seem to be more worried about about the fine dust (2.5) which articles are saying are more locally made than traveled. korea only started taking readings of the fine dust since 2014(?). another aspect that most people gloss over is that korea sends a lot of their assembly to china and articles have stated that those factories tend to be right across the sea. soooooo it's still kind of a korean problem for exporting factory work right across the sea. it also still means that korea should actively pursue measures the clean up locally because you can't control standards in China.
Although the major components of yellow dust are sand and materials from the earth's crust, various industrial pollutants, including mercury and cadmium, have also contributed to the dust problem because of the rapid industrialization of China. The smaller, reparable portion of yellow dust has greater health effects. While yellow dust is of natural origin, fine and ultrafine dust is largely of man-made origin. Secondary particles from the oxidation of primary particles forming sulfuric acid, nitric acid, ammonium salts, volatile organic compounds, and black carbon are hazardous. The major anthropogenic source of the dust is combustion products of fossil fuel. Approximately 30% of sulfuric acid and 40% of nitric acid in ambient air in Korea might have been migrated from China. To reduce the transboundary pollution from China, collaborative actions between Korea and China are needed.

The yellow dust tends to collect industrial toxins as it migrates.

Hundreds of flights grounded due to dense fine dust smog pollution fog in South Korea Foggy conditions on Christmas Eve have forced several cancellations and delays at South Korea's main gateway.As of 10 a.m. on Sunday, 34 outbound and nine inbound flights at Incheon International Airport have been delayed, according to Incheon International Airport Corp. (IIAC). In addition, five outbound and six inbound flights have been canceled.Thick fog on the western coast, where the airport is situated, also caused 312 delays and 49 cancellations Saturday. The IIAC said 43 other flights bound for Incheon were forced to land at other airports in the country.An IIAC official said delayed or canceled flights from Saturday have caused a logjam on Sunday, and it won't be until late afternoon that the operations will be back to normal.The Aviation Meteorological Office issued a low visibility warning at Incheon International Airport at 1:35 a.m. Sunday and lifted it some four hours later.This type of warning is issued when the visibility is under 400 meters, and the visibility at the airport dropped to 50 meters at one point Saturday.While the airport officials were grappling with fog, other parts of the country were blanketed by ultrafine dust Sunday.
Environmental issues have rarely received attention in South Korean elections, but the nation’s worst-ever air pollution in the first three months of this year has changed that. With slightly over a month left to the May 9 presidential election, major contenders are releasing pledges on tackling the aggravating fine dust problem, facing conspicuously growing public awareness and voter demand. http://www.koreaherald.com/view.php?ud=20170407000681“Blue skies and clean air are what our children deserve,” Moon said, promising that he would introduce stricter air quality standards for children to be applied for day cares, kindergartens and schools. Revealing he received over 2,000 text messages from voters concerning air quality, he promised to pursue the air problem as one of his top priorities, if elected. Ahn Cheol-soo of the centrist People’s Party, second in the polls, stressed that South Korea alone could not solve the fine dust issue.“Since a lot of the particles come from China, the matter has to be resolved with diplomatic means,” he said, adding that Korea’s “foreign policy must cover environmental issues.”
