Separate data from the World Bank showed that in 2013, a total of 57,403 Filipinos prematurely died because of air pollution-related causes — up nearly 33 percent from the levels in 1990.
Various studies have shown that those who are more exposed to charcoal burning are at higher risk of developing respiratory diseases, such as chronic obstructive pulmonary disease and lung cancer.
It may also exacerbate heart diseases and make one more prone to strokes.
This is due to the pollutants, such as fine particles of PM2.5, nitrogen oxide and black carbon, which are emitted when burning charcoal, Kass said.
