Mobile Monitoring and Land Use Regression Modeling of Ultrafine Particle Spatial Distribution in Beijing, China, during August 2022–July 2023

Key Points

• To quantitatively assess the spatial variability of ultrafine particles (UFP) in Beijing from August 2022 to July 2023.
• Conducted mobile monitoring to collect UFP data across various locations in Beijing.
• Applied land use regression modeling to analyze the collected data and identify spatial patterns.
• Focused on areas with high population density and major roadways.
• Identified hotspots of ultrafine particle concentration particularly in the urban core and near major roadways.
• Demonstrated significant spatial variability in UFP levels across evaluated areas in Beijing.
