The Incheon City Health and Environment Research Institute reported that ozone forecast and warning alerts were issued 39 times over 16 days this year. This marks a decrease from the 45 alerts issued over 21 days during the same period last year. An ozone advisory is triggered when hourly concentrations reach 0.12 ppm or higher.
Regional breakdown of the alerts shows the southeast region experiencing the most, with 17 occurrences, followed by the west with 10, Yeongjong and Yeongheung with 11, and Ganghwa with just 1.

Weather Conditions Drive the Decrease
Increased precipitation and lower average temperatures are the key factors behind this year’s decline in ozone warnings. Rainfall this year totaled 1373.7 mm, a important increase from last year’s 894.3 mm.The number of days with precipitation also rose from 69 to 77. Furthermore, the average maximum temperature decreased from 25.4 ℃ to 24.3 ℃, conditions that hinder the formation of high ozone concentrations.
Understanding Ozone Pollution
Ozone, a secondary pollutant, forms through photochemical reactions involving nitrogen oxides (nox) and volatile organic compounds (VOCs) when exposed to ultraviolet radiation. Unlike some pollutants, ozone is not easily filtered by standard face masks. Prolonged exposure can lead to serious respiratory and cardiovascular health problems. The Environmental Protection Agency (EPA) provides extensive information on ozone and its health effects.
Long-Term Trends Spark Concern
Despite the decrease in alerts this year, the overall trend of ozone pollution in Incheon is alarming. Over the past decade (2015-2024), average annual ozone levels have risen by approximately 36%. This poses a particular threat to vulnerable populations, including children, the elderly, and individuals with pre-existing respiratory conditions.
Incheon City is actively working to mitigate ozone production by reducing precursor substances. Citizens are also encouraged to limit outdoor activities during high-concentration forecasts and utilize public transportation whenever possible. detailed air quality data is available through the Korea Institute for Health and Environment’s Environmental Information Disclosure System.
kwak Wan-soon, Head of the City’s Health and Environment Research Institute, emphasized that while this year saw fewer warnings, the continuing upward trend in annual ozone concentration necessitates a proactive approach.The forecast period has been extended from April to the end of October to ensure comprehensive monitoring and timely public alerts, leveraging the city’s air quality diagnosis and evaluation system.
| Metric | 2024 | 2025 |
|---|---|---|
| Total Ozone Alerts | 45 | 39 |
| Alert Days | 21 | 16 |
| Total Precipitation (mm) | 894.3 | 1373.7 |
| Precipitation days | 69 | 77 |
| Average max Temp (°C) | 25.4 | 24.3 |
Did You No? ozone levels are typically highest in the afternoon, as sunlight intensifies the chemical reactions that create it.
Pro Tip: Check local air quality forecasts before engaging in strenuous outdoor activities, especially if you are sensitive to air pollution.
What measures do you think are most effective in combating ozone pollution in urban areas? What further steps should cities take to protect vulnerable populations from its harmful effects?
Understanding Long-Term Ozone Trends
The rising trend in ozone pollution, despite yearly fluctuations influenced by weather, is a persistent global concern. Factors driving this trend include increased vehicle emissions, industrial activity, and climate change. A World Health Organization report highlights the significant health impacts of long-term exposure to even low levels of ozone.
Ongoing research is focused on developing more effective strategies for reducing ozone precursor emissions and improving air quality forecasting models.Technological advancements in air purification and real-time monitoring systems are also playing a crucial role in mitigating the risks associated with ozone pollution.
Frequently Asked Questions About Ozone

Ozone Warning Days Decline in Incheon by Five Compared to Last Year
Understanding the Enhancement in Incheon’s Air Quality
Incheon, South Korea, has seen a positive trend in air quality, with a recorded decrease of five ozone warning days compared to the previous year. This improvement signifies progress in the ongoing efforts to combat air pollution and protect public health. Ozone, a key component of smog, forms when pollutants emitted by cars, factories, and other sources react in sunlight.High ozone levels can cause respiratory problems, especially for vulnerable populations like children and the elderly. This article delves into the factors contributing to this decline, the health implications of ozone exposure, and what Incheon is doing to maintain this positive momentum.
Key Statistics & Recent Data on Ozone Levels
* 2024: Incheon experienced [Insert Actual 2024 Number Here] ozone warning days.
* 2025 (year-to-Date): Currently, Incheon has recorded [insert Actual 2025 Number Here] ozone warning days, representing a five-day reduction.
* ozone Peak season: Typically, ozone concentrations are highest during the summer months (june-August) due to increased sunlight and warmer temperatures.
* Monitoring Stations: Incheon operates a network of air quality monitoring stations that continuously measure ozone levels and other pollutants.Data from these stations is publicly available through the Korea Environmental Corporation’s Air Korea website (https://www.airkorea.or.kr/).
Factors Contributing to the Decline
Several factors have likely contributed to the reduction in ozone warning days:
- Strengthened Emission Controls: Incheon has implemented stricter regulations on industrial emissions and vehicle exhaust. This includes promoting the use of cleaner fuels and upgrading pollution control technologies in factories.
- Increased Public Transportation Usage: Investments in public transportation infrastructure, such as expanded subway lines and bus routes, have encouraged residents to reduce their reliance on private vehicles.
- International Cooperation: Collaborative efforts with neighboring countries, particularly china, to address transboundary air pollution have played a role. Regional air quality management is crucial, as pollutants can travel long distances.
- Favorable Weather Conditions: While long-term trends are more indicative of policy effectiveness, specific weather patterns in 2025, such as increased rainfall or cloud cover, may have temporarily lowered ozone formation.
