Ozone advisories issued across Gyeonggi Province, South Korea; residents urged to limit outdoor activity

Ozone advisories have been issued for large parts of Gyeonggi Province, South Korea, as high concentrations of the pollutant have been detected. Following an advisory in the northern part of the province earlier in the day, the central and eastern regions also came under warnings on May 30.

The Environmental Ministry's Air Environment Corporation announced that 18 cities and counties in the central and eastern areas, including Suwon, Seongnam, and Namyangju, were issued ozone advisories. The average ozone concentration in the central region reached 0.1309ppm, and 0.1254ppm in the eastern region as of 1 p.m. An ozone advisory is typically issued when the hourly average ozone concentration exceeds 0.12ppm.

Earlier, eight cities and counties in the northern Gyeonggi region, such as Goyang, Uijeongbu, and Paju, also received ozone advisories. The concentration levels in these areas also surpassed the threshold for concern.

Authorities are advising residents to exercise caution. The advisories specifically recommend that the elderly, children, and individuals with pre-existing respiratory or heart conditions should refrain from outdoor activities. Even for the general population, it is recommended to avoid strenuous outdoor exercise and limit time spent outside until the advisories are lifted.
