Dissertation note: College of Science .-- Bachelor of Science in Environmental Science: Technological University of the Philippines, 2024. Summary: Recent findings have indicated the presence of microplastics measuring less than 5 mm. This suggests that these particles may be transported through the atmosphere over great distances. However, limited data exists regarding the amount, pattern, transmission, and effects of these suspended atmospheric microplastics (SAMPs) in the Philippines. To address this gap, a study was conducted to investigate the presence of suspected microplastics in the atmosphere along Epifanio de los Santos Avenue, namely, Taft station, Shaw station, and Eton station within Metro Manila, Philippines. Sampling was carried out using a respirable dust sampler equipped with Whatman GF/C filter paper and an intake flow rate of 1.4 L/min. Nine filter papers were subjected to the picking method. In total, 1,074 SAMPs were collected along EDSA and analyzed for morphological characteristics, including color, shape, and size, as well as chemical analysis using FTIR; most of them were fiber-shaped and blue in color, with the highest concentrations observed in Shawn Station (404.18 particles/NCM). Polyethylene terephthalate (PET) was the most abundant of this type of SAMP, with approximately 36%. A result of 2–18 numbers of suspended atmospheric microplastics were computed for normal commuters along EDSA that were being inhaled. This study represents the second documentation of microplastics suspended in ambient air in the Philippines and the first along EDSA that highlights the potential inhalation exposure of individuals. To determine the final outcome and health effects of these SAMPs in the Philippines.

Recent findings have indicated the presence of microplastics measuring less than 5
mm. This suggests that these particles may be transported through the atmosphere over
great distances. However, limited data exists regarding the amount, pattern, transmission,
and effects of these suspended atmospheric microplastics (SAMPs) in the Philippines. To
address this gap, a study was conducted to investigate the presence of suspected
microplastics in the atmosphere along Epifanio de los Santos Avenue, namely, Taft station,
Shaw station, and Eton station within Metro Manila, Philippines. Sampling was carried out
using a respirable dust sampler equipped with Whatman GF/C filter paper and an intake
flow rate of 1.4 L/min. Nine filter papers were subjected to the picking method. In total,
1,074 SAMPs were collected along EDSA and analyzed for morphological characteristics,
including color, shape, and size, as well as chemical analysis using FTIR; most of them
were fiber-shaped and blue in color, with the highest concentrations observed in Shawn
Station (404.18 particles/NCM). Polyethylene terephthalate (PET) was the most abundant
of this type of SAMP, with approximately 36%. A result of 2–18 numbers of suspended
atmospheric microplastics were computed for normal commuters along EDSA that were
being inhaled. This study represents the second documentation of microplastics suspended
in ambient air in the Philippines and the first along EDSA that highlights the potential
inhalation exposure of individuals. To determine the final outcome and health effects of
these SAMPs in the Philippines.
