I. Introduction
Industrialization and urbanization worldwide are causing an influx of air pollution, which in turn is leading to negative im-pacts on human health, deforestation, and habitat destruction. The trend to move towards urban cities and Central Business Districts, particularly in developing countries, is leading to record-breaking levels of PM2.5 year after year [Yang et al., 2018]. In fact, according to Zhou et al. [2017], over the past decade, the number of deaths caused by the harmful effects of ambient PM2.5 have increased by 23%. PM2.5's ability to travel deep into human respiratory tracts can cause premature death to those with pre-existing heart and lung conditions. Its effects on human health transcend across age groups and can worsen diseases such as COPD, asthma, pulmonary fibrosis, and pneumonia [Xing et al., 2016].
