It is widely acknowledged that air pollution is a serious problem in Metro Manila. Suspended particles, especially PM10 (particulate matter with a diameter of 10 microns or less) is now considered the priority air pollutant. The largest contributors to PM10 are fossil fuel combustion in small and medium industrial and commercial installations, and construction activities. Vehicle exhaust contributes about 12% of total TSP emissions. Within this category the largest contributors are diesel trucks, buses, and jeepneys.

Sulfur dioxide and total oxidants occasionally exceed the standards, while nitrogen oxides, ozone, and carbon monoxide levels all remain within the standards. Ambient levels of lead have dropped significantly (Source: Philippines Environment Monitor, 2000).
