Ultrafine dust warnings issued in the Seoul metropolitan area...You need to prepare a health mask for KF80 or higher

Jan 20, 2025

Once again, ultrafine dust is threatening health.

An ultra-fine dust warning was issued in the Seoul metropolitan area on the 20th, and this situation is expected to continue on the 21st. The ultrafine dust warning is issued if the average concentration of ultrafine dust per hour is 75㎍/㎥ or more for two hours. This is the first time this winter that an ultra fine dust warning has been issued in Seoul.

Starting with Yeongjong and Yeongheung areas in Incheon at 9 a.m. on the 20th, ultrafine dust warnings were issued in western and southeastern Incheon at 11 a.m. and central Gyeonggi Province at 12 p.m. in Seoul. Additional ultrafine dust warnings were issued at 1 p.m. in the Ganghwa area of Incheon and at 2 p.m. in the southern, eastern and northern parts of Gyeonggi Province.




The National Institute of Environmental Research predicts that the average daily concentration of ultrafine dust in the metropolitan area and Chungnam will exceed the standard of 50㎍/㎥ for issuing high-concentration fine dust emergency reduction measures. In Chungnam, preliminary reduction measures, including the two-day system for owned and entered vehicles by public institutions, are already in effect, and the air is stagnant on the 21st and fine dust is not expected to escape.

Such ultrafine dust (PM2.5) is very small, with a diameter of less than 2.5 μm, and when breathing, it can enter the end of the alveoli and enter the blood vessels directly. It is about one-thirtieth the thickness of a hair.

According to the Korea Centers for Disease Control and Prevention, exposure to fine dust can cause or worsen heart and lung-related diseases, and consequently can affect increased deaths. In the short term, symptoms such as asthma attacks, acute bronchitis, and arrhythmia worsen, and long exposure at high levels of fine dust increases the risk of cardiovascular disease, respiratory disease, and lung cancer. In addition, active oxygen is supplied to various organs to promote cell aging and promote inflammatory reactions, resulting in tissue damage. Since this action takes place throughout the body along the bloodstream, it can affect not only the respiratory tract but also various organs of the body. Although there are no special symptoms or diseases caused by exposure to fine dust, it can cause or worsen various symptoms and diseases.




Sensitive groups such as pregnant women, infants, children, the elderly, cardio-cerebrovascular patients, and respiratory and allergic patients should be particularly careful because they are at greater risk from exposure to fine dust.

First of all, preventive measures such as refraining from going out on days when the concentration of fine dust is high and purifying indoor air are necessary.

Inevitably, it is recommended to wear a health mask such as KF80 and KF94. In addition, washing your hands after returning from an outing helps prevent respiratory diseases. Drinking water properly helps maintain the body's resistance, and eating fruits or vegetables rich in antioxidants such as vitamin C helps reduce the health effects of fine dust. In addition, it is possible to use an air purifier along with proper ventilation and reduce the effect of fine dust through wet mop.
