- But DENR XI warns vulnerable groups of prolonged haze exposure
THE DEPARTMENT of Environment and Natural Resources (DENR) XI said that its monitoring across stations reported air quality that remains “good” despite the onset of haze affecting parts of the country.
However, the agency reminds the public to remain vigilant and follow updates as haze conditions may cause fluctuations in air quality.
As of September 1, 2026, air quality monitoring in Malita, Digos, and Calinan stations shows generally acceptable levels of particulate matter (PM10 and PM2.5).
Particulate matter (PM) contains microscopic particles and liquid droplets that can cause serious health problems.
PM levels are a key indicator measuring air quality, tracking pollution levels, and protecting public health.
Data collected from Aug. 26 to Sept. 1, 2026, indicate that the Malita Station consistently recorded good air quality, with PM10 and PM2.5 values well within safe thresholds.
Meanwhile, Digos and Calinan Stations registered fair air quality levels, with occasional readings categorized as “unhealthy for sensitive groups,” particularly for PM2.5 concentrations.
DENR XI reported the elevated values are attributed to transboundary haze episodes originating from Indonesia. The agency advised the general public to continue outdoor activities under good and fair conditions.
Meanwhile, sensitive groups, including children, the elderly, and individuals with respiratory conditions, are advised to limit prolonged outdoor exposure during periods classified as “unhealthy for sensitive groups.”
“While most monitoring stations report air quality within acceptable ranges, the presence of haze has led to localized increases in PM2.5,” Environment Management Bureau XI regional director Alnulfo Alvarez said.
The agency continues to monitor air quality closely, urging the public to check issued timely updates to safeguard public health.
