[Asia Economy Reporter Lee Seon-ae] On the afternoon of the 13th, fine dust (PM2.5) concentrations are showing a 'Bad' level in most regions nationwide.

The National Institute of Environmental Research's Air Quality Integrated Forecast Center announced that on this day, fine dust (PM2.5) concentrations are 'Bad' in the Seoul metropolitan area, Gangwon Yeongseo, Chungcheong region, Honam region, and Daegu, while other regions are 'Moderate.'

However, Jeju region is expected to temporarily reach 'Bad' levels at night.

As of 1 PM, the hourly average PM2.5 concentrations by major cities and provinces are 63㎍/㎥ in Chungnam, 59㎍/㎥ in Jeonbuk, 51㎍/㎥ in Incheon, 45㎍/㎥ in Sejong, and 44㎍/㎥ in Gyeonggi and Seoul.

The National Institute of Environmental Research explained, "In the central-western region and some southern areas, fine dust remaining from the previous day is accumulating due to stagnant air and converging airflows, resulting in high concentrations."

On the 14th, except for some western areas, PM2.5 concentrations are expected to decrease across all regions.

Incheon, southern Gyeonggi, Chungnam, and Jeonbuk are forecasted to have 'Bad' levels, while other regions will range from 'Good' to 'Moderate.'

The National Institute of Environmental Research stated, "Some western areas will have high concentrations due to residual fine dust from the previous day."
