[Sejong=Asia Economy Reporter Joo Sang-don] On the 29th, fine dust warnings were issued in 10 cities and provinces nationwide, including the Seoul metropolitan area, Gangwon, Daejeon, Sejong, Chungbuk, Chungnam, Gyeongnam, and Jeonbuk.

The Ministry of Environment announced that as of 7 a.m. that day, it had issued fine dust 'warnings' and yellow dust crisis alert 'caution' levels in 10 cities and provinces.

This is an upgrade from the previous day's yellow dust crisis alert 'interest' level to 'caution.' The 'interest' level is issued when fine dust (PM10) caused by yellow dust is forecasted to be 'very bad' (daily average PM10 exceeding 150㎍/㎥), and the 'caution' level is issued when fine dust concentration exceeds 300㎍/㎥ per hour for two consecutive hours.

With the issuance of the yellow dust crisis alert caution level, the Ministry of Environment established the Central Yellow Dust Countermeasures Situation Room according to the yellow dust response manual and requested related organizations and local governments to respond according to the manual. Accordingly, the following measures are implemented: ▲ prohibition of outdoor classes and activities at schools ▲ damage prevention measures for sensitive groups ▲ wearing masks and protective goggles for outdoor long-term workers ▲ monitoring of aircraft operation status and strengthening inspection of navigation safety facilities.
