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 exposure Faculty of Industrial Sciences and Technology Dissertations Universities and colleges Dissertations Final Year Report Dissertations http://umpir.ump.edu.my/id/eprint/45535 lcc PSM 0 0 lcc 0 0 10000 10000 2026-01-15 0 FIST .A45 2025 r Bc.
