This study investigates airborne microplastics (MPs) in office environments, with a particular focus on spaces air conditioning (AC), due to increasing health concerns. The research aims analyze the physical characteristics, sources, distribution, and potential risks of MPs. Despite growing awareness MP pollution, comprehensive data their specifics settings—such as shape, composition, size—remains limited. Between November 2023 January 2024, 42 samples were collected under controlled conditions, both without AC, at Air Resource Research Laboratory, Universiti Teknologi Malaysia Kuala Lumpur Campus. Stereomicroscopy was employed identify MPs’ properties, revealing dominance bead-shaped MPs air-conditioned spaces, smaller particles (<50µm), often transparent or black, being most prevalent. Environmental factors like wind speed humidity found influence MPs' abundance. also noted correlation between atmospheric particulate matter (PM) emissions, suggesting shared sources accumulation mechanisms. Estimates daily intake through dust ingestion highlighted associated risks. provides insights into dynamics PM offices, emphasizing need for further investigation environmental impacts. Effective mitigation strategies are crucial reducing exposure, thereby improving indoor quality protecting human health.
