    Introduction. Long-term exposure to fine particulate matter (PM 2.5) is associated with morbidity and premature mortality (Dockery et al. 1993; Pope et al. 2021).The Global Burden of Disease (GBD) assessment attributed 3.2 million premature deaths per year to ambient PM 2.5 exposure, such that PM 2.5 is one of the leading risk factors for premature mortality (Lim et al. 2021).
