by Achilles Costales, Maria Angeles Catelo, Harvey Baldovino, Winona Bolislis, Dorothy Bantasan

This study determined the health costs that air pollution imposes on the constituents of Baguio City. It used the cost of illness (COI) approach to value the economic burden that households bear for having a household member falling ill or dying due to an air pollution-related disease. The results indicated that chronic exposure to PM10 concentration levels that are four times higher than that of the WHO Air Quality Guideline for PM10 (set at 20 µg/m3) significantly affects the exposed population. Around 157 annual cases of premature nontraumatic adult mortality were attributable to being exposed to PM10 concentrations at historical mean concentration levels. This amounted to around 14% of the total number of premature nontraumatic mortalities in Baguio City in 2013. These attributable cases were valued at PHP 53.3 million per year in terms of lost productivity. Around 4,758 attributable cases per year of cardiovascular and respiratory illness were estimated, accounting for about 22% of all cases of the identified cardiovascular and respiratory cases of morbidity in Baguio in 2013. The direct cost of illness and the indirect costs due to lost days of the otherwise productive patients and caregivers amounted to around PHP 24 million per annum. The COI due to exposure to local PM10 concentration levels relative to the WHO AQG of 20 µg/m3 amounted to PHP 77.4 million per annum.
