2. A study DOH sponsored along with the Department of Environment and Natural Resources, World Health Organization, and Asian Development Bank showed that Metro Manila's air quality was poor, and the volume of particulate matter in its atmosphere was above the baseline level of 50 micrograms per cubic meter (ug/m3) for clean air.
4. Cities considered high risk or extremely polluted were Caloocan, Valenzuela, and Quezon City.
Quezon City air was deemed most polluted, with 96.9% of PM10 and 78.3% of PM2.5 or fine grain particulates.

As a resident of Metro Manila, how can you help reduce the air pollution? What is your suggestion to reduce it, if not totally eradicated it? ( Bilang isa sa mga nakatira/residente sa Metro Manila (Quezon City), ano ang iyong maisusuhestiyon o maitutulong upang mabawasan ang polusyon sa hangin?)
