Makati City and North Caloocan reached “emergency” air quality levels on New Year’s Day, with an air quality index of 301, the DENR-EMB reported.
Under this level, the agency advised everyone to stay indoors, keep windows closed, and restrict motor vehicle use except for emergencies.
Taguig recorded “acutely unhealthy” air with an index of 289, prompting residents, especially those with heart or respiratory conditions, to limit outdoor activities.
DENR-EMB’s monitoring stations measured fine particles under 2.5 micrometers, which can penetrate the lungs and bloodstream, while a second station measured larger particles under 10 micrometers.
The agency warned that industrial activities and unnecessary trips may be curtailed to reduce exposure during hazardous air conditions.
