An ozone advisory has been issued for eight districts in the northeastern area of Seoul.

The Seoul Institute of Health and Environment announced on the 1st at 3 p.m. that an ozone advisory is in effect for Seongdong, Gwangjin, Dongdaemun, Jungnang, Seongbuk, Gangbuk, Dobong, and Nowon districts in the northeastern region.

Seoul city issues an advisory when the one-hour average ozone concentration in the autonomous districts within the area reaches 0.120 ppm or higher.

Ozone is a secondary pollutant formed when volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the atmosphere react photochemically with solar energy. High concentrations of ozone can irritate the respiratory system and eyes, causing inflammation and, in severe cases, respiratory disorders.

The institute urged, "Children, the elderly, and those with respiratory or cardiovascular diseases should refrain from outdoor activities."
