Analysis of airborne microplastics using μ-raman spectroscopy in Seoul
AI summary Read the abstract
Monthly air sampling in Seoul using µ-Raman spectroscopy found a mean airborne microplastic concentration of 74 particles/m³, dominated by polyethylene (47%) and polystyrene (22%) fragments in the 5–10 µm respirable size range. Because particles in this size range penetrate deep into the lungs and have already been detected in human lung tissue, this baseline data is important for assessing inhalation as a significant route of human microplastic exposure in urban environments.
