A recent study “Source apportionment of key air pollutants in Naples using a high-resolution WRF-CAMx-PSAT modeling framework”, is published in Atmospheric Environment. The research integrated detailed emission inventories and ARPA Campania monitoring data to accurately simulate concentrations of NO₂, PM₂.₅, PM₁₀, and SO₂.
 
The source apportionment analysis highlighted:
• Road transport and residential heating as the dominant sources of NO₂, PM₁₀, and PM₂.₅ in urban and suburban areas.
• Maritime activities with significant impacts on SO₂ and NO₂ at coastal locations, particularly near the Port of Naples.
• Natural sources (sea salt and secondary organic aerosols) contributing notably to PM levels in inland areas.
 
These findings provide actionable insights for targeted emission reduction strategies and evidence-based air quality management in complex coastal urban environments.
