The  research aimed to determine the concentration of MPs in indoor air, identify their I/O ratios, and explore  the correlation between various factors influencing MP concentrations. Nine samples were collected  from three daycare centres which located in Kuantan District, Pahang, the concentration of indoor AMP  is markedly higher than the outdoor AMP where Daycare Centre B accounted for 89.79 MP/m3  (74.69- 109.17) MP/m3  indoor and 86.88 MP/m3  (69.38-90.10) MP/m3 outdoor and Daycare Centre C with  median (IQR) indoor and outdoor AMP concentration was 161.88 (123.44-170.63) MP/m3  and 112.71  (81.56-121.25) MP/m3. The analysis revealed an average indoor-to-outdoor ratio of 1, indicating higher  levels of MPs indoors than outdoor environments. Additionally, no significant correlations (p > 0.05)  were found between indoor MP concentrations and driving factors (indoor air velocity, indoor  temperature, indoor relative humidity, number of occupants, type of building, type of ventilation EDI  ranges from 136.54 to 278.69 MP/kg-day. There is an inverse relationship between teacher bodyweight  and EDI. The study concluded that daycare centers are critical environments for monitoring AMP  exposure, emphasizing the need for improved air quality standards to protect teachers from developing  chronic respiratory problems from prolonged exposure20aFaculty of Industrial Sciences and TechnologyxDissertations 0aUniversities and collegesxDissertations 0aFinal Year ReportxDissertations  uhttp://umpir.ump.edu.my/id/eprint/45535
