The regions are Yongin, Pyeongtaek, Icheon, Anseong, and Yeoju.
The average ultrafine dust warning concentration in this area per hour is 82㎍ (microgram, 1 millionth of a gram) / ㎥.
The ultrafine dust warning is issued when the time-average ultrafine dust concentration is 75㎍ / ㎥ or more and continues for 2 hours.
Ultrafine dust advisories were maintained in 19 cities and counties in the central and northern regions.
If the concentration of ultrafine or fine dust in the air increases, the elderly, children, people with respiratory and cardiovascular diseases should refrain from outdoor activities.
To become a healthy adult, it is best to reduce the time you spend outdoors and wear a mask when you go out.
In particular, ultrafine dust is about half the thickness of a hair, so it does not leak out of the respiratory tract and enters the lungs as is.
