Metro Cebu Air Quality Improves to 'Fair' After Hazardous Haze Subsides
Air quality in Metro Cebu has significantly improved, reaching a "fair" rating on Wednesday, April 22, 2026. This positive shift comes after the air quality index (AQI) dropped dramatically from its weekend peak, offering relief to residents following days of hazardous conditions.
Lingering Risks for Sensitive Groups
Despite the improvement, the Environmental Management Bureau (EMB) 7 cautioned that the AQI of 98 as of Wednesday remains at the upper end of the "fair" range. This means sensitive groups, such as children, the elderly, and individuals with respiratory issues, could still experience slight health effects. The agency emphasized the need for continued vigilance.
From 'Very Unhealthy' to 'Fair'
The EMB 7 reported a remarkable recovery from a peak AQI of 199 on Sunday, April 19, when air quality was classified as "very unhealthy." The haze that had lingered for nearly a week largely dissipated, thanks to stronger winds and natural ventilation. These factors helped disperse accumulated fine particulate matter (PM2.5), the primary pollutant.
PM2.5 refers to fine particles measuring 2.5 micrometers or smaller, which can penetrate deep into the lungs and bloodstream, posing serious health risks.
Timeline of Pollution Episode
The pollution episode began with a spike as early as April 13, deteriorating to "unhealthy for sensitive groups" by Friday, April 17, and worsening over the weekend. By Monday, April 20, the AQI slightly eased to 177 before further improving to 98 by Tuesday, April 22.
Causes and Health Advisories
The EMB 7 attributed the haze to localized emissions, including vehicle exhaust, road dust, industrial activities, and small-scale fires. Combined with hot weather and weak winds, these created a "zero-dispersion" effect, trapping pollutants in the air. At its peak on Sunday, PM2.5 concentrations reached 50.3 micrograms per cubic meter, exceeding the 35-microgram safety limit.
In response, the Department of Health Central Visayas issued a health advisory on Tuesday, April 21, warning that air quality could affect all individuals, particularly vulnerable groups. The agency urged the public to:
- Limit outdoor exposure
- Ensure proper ventilation
- Wear protective masks when necessary
- Seek medical attention if symptoms occur
Precautions and Sustainability Efforts
Despite the improvement, the EMB 7 advised sensitive groups to limit prolonged outdoor activity. The general public may resume normal activities but should remain alert for symptoms such as coughing or throat irritation. To sustain improved conditions, residents are urged to:
- Avoid open burning
- Reduce vehicle emissions
- Report fires promptly
The bureau noted that pollution could build up again if stagnant conditions return, highlighting the importance of community efforts in maintaining air quality.
