Air Raid

South Korea has been blindsided by fine-particle dust air pollution, just in time for the annual spring siege of "Yellow Dust."  Shoppers are responding:

"For the last few weeks, Korea has been under siege by the worst fine dust the country has ever seen, not only in terms of severity but also longevity. In some regions like Gwangju and South Jeolla, a government-issued fine dust warning lasted eight days, the longest since the system was implemented in 2015.

While periods of acute pollution have always affected the market - generally by boosting sales of masks and air purifiers - this year things got so bad that the impact was much broader, changing consumer behavior and prompting the launch of new products and services as desperate Koreans look for ways to combat the fine dust."

Daegu has been spared for the most part, but friends of mine in Seoul are reporting that things are pretty awful.
