Chungnam to Operate 'Ozone Alert System' from April to October and Measure Ozone Levels in Real Time

[Asia Economy (Naepo) Reporter Jeong Il-woong] Chungnam Province will operate the ‘Ozone Alert System’ for six months starting this month and conduct real-time ozone measurements.

The Provincial Health and Environment Research Institute announced on the 14th that the ‘Ozone Alert System’ will be implemented from the 15th of this month to October 15th.

The Ozone Alert System is a type of management system designed to minimize the impact of ozone on residents' health. It measures ozone concentration in the atmosphere and issues a ‘Caution’ alert if it reaches 0.12ppm or higher, a ‘Warning’ at 0.3ppm or higher, and a ‘Severe Warning’ at 0.5ppm or higher, allowing for appropriate responses.

To this end, the province conducts real-time measurements through air pollution monitoring stations installed at 32 locations across 15 cities and counties within the province.

Ozone is typically formed when air pollutants such as nitrogen oxides and volatile organic compounds undergo photochemical reactions in sunlight. It tends to be higher when temperatures are high, relative humidity is low, and winds are weak.

Prolonged exposure to high concentrations of ozone, which is highly irritating and oxidative, can cause headaches, coughing, chest tightness, and eye irritation, and in severe cases, lead to reduced lung function and other health damages.

Therefore, when an ozone caution alert is issued, the Provincial Health and Environment Research Institute advises respiratory patients, the elderly, and children to avoid outdoor activities as much as possible, and during a warning, all residents should refrain from outdoor activities or strenuous exercise.

In particular, last year, a total of 44 ozone caution alerts were issued, with 35 of them (80%) occurring in the strong sunlight afternoons of May and June, requiring special attention.

The Provincial Health and Environment Research Institute is currently providing a text alert service for ozone caution alerts, and applications for the alert service can be made through the province’s or the Health and Environment Research Institute’s website.

Ozone concentration and alert status can also be checked on Air Korea, the nationwide real-time air pollution disclosure site.
