‘7 million people die annually due to air pollution’

CLARK FIELD, Pampanga , Philippines — At least 100 of every 100,000 Filipinos die annually because of air pollution, an expert from the Manila Observatory revealed.

“Roughly seven million people die each year, that’s globally, due to air pollution, a third of that figure is actually in Asia. In the Philippines, that’s 100 people per 100,000 (dying) each year due to air pollution,” said Maria Obiminda Cambaliza, Manila Observatory air quality dynamics laboratory research scientist, as she cited data from the World Health Organization (WHO) during a press conference here last week.

Cambaliza added that 60 percent of the country’s air pollution was caused by vehicles.

“Based on our study, the major contributor to the particulate matter 2.5 was due to the transportation sector, due to traffic. The rest are other sources, like construction, natural causes, like sea salt, dust,” she also said.

As an example, Cambaliza cited the incident on Sept. 22, 2023 when smog covered the National Capital Region due to air pollution.

“We did a quick analysis and we found out… it was not due to the vog but due to the pollution in Metro Manila. This means that the air pollution that we produce causes haze. The winds were very low so whatever was emitted by our sources, like the transportation sector, stayed in our atmosphere because we lacked dispersion from the winds. The emission did not flow, what was emitted stayed,” she explained.

According to Cambaliza, the country’s annual air quality was pegged at 20 micrograms per normal cubic meter, or four times the annual standard value set by the WHO.

A memorandum of understanding – signed between Environment Secretary Maria Antonia Yulo-Loyzaga and National Aeronautics and Space Administration tropospheric composition program scientist Barry Lefer – allows experts from the Department of Environment and Natural Resources to join NASA scientists on board scientific research flights from Feb. 11 to 15.

The program aims to study the atmosphere in Metro Manila and nearby regions, including Regions 3 and 4-A and the provinces of Ilocos Norte, Cebu and Palawan.
