‘Very unhealthy’ air quality recorded in parts of Metro Manila

Residents in parts of Metro Manila were advised to wear face masks after “very unhealthy” levels of fine particulate matter (PM2.5) were recorded on Sunday, April 19.

PM2.5 refers to tiny solid particles and liquid droplets in the air measuring 2.5 micrometers or smaller in diameter, which can penetrate deep into the lungs.

As of 3:00 p.m., “very unhealthy” PM2.5 levels were logged in Caloocan, Malabon City, Marikina CEMO, and Quezon City.

Air quality in Navotas City—where a burning landfill has been contributing to smog affecting nearby areas—was classified as “unhealthy.”

Meanwhile, PM2.5 levels in Mandaluyong City and Muntinlupa City were considered “fair.”

Data from the Environmental Management Bureau’s air quality monitoring system showed that common sources of PM2.5 pollution in Metro Manila include motor vehicle emissions, construction and road dust, waste management practices, and biomass burning.

Experts warn that short-term exposure to PM2.5 may lead to serious health effects, including increased risk of premature death among people with heart or lung disease, nonfatal heart attacks, irregular heartbeat, aggravated asthma, reduced lung function, and worsening respiratory symptoms.—MCG, GMA News
