South Korea is still choking under heavy clouds of ultra-fine dust,... on the last day of the long weekend here in the nation.
Fine dust advisories have been issued in most parts of the country,... with concentration levels in the Seoul capital region, Chungcheong and Jeollabuk-do provinces... being three to five times higher than normal.
The nation's weather bureau says... the air pollution could linger for an extended period of time... due to a still atmosphere over Korea which is trapping fine dust particles.
