Assessing the impact of ship emissions on the atmospheric chemical composition in the Eastern Mediterranean and the Piraeus port (Greece).

ABSTRACT: This study examined the impact of shipping emissions on the atmospheric composition and oxidation capacity in the Eastern Mediterranean, focusing on Greece and the Piraeus port. The analysis used CAMx air quality modeling (simulations for January and July 2019), Positive Matrix Factorization (PMF) receptor modeling, and ship emission inventories from CAMS-REGv6.1 and the "Flexible Emission Inventory for Greece and the Greater Athens Area" (FEI-GREGAA). Zeroing out shipping emissions within Greek maritime waters resulted in substantial reductions in monthly concentrations of pollutants in major Aegean Sea shipping corridors, becoming largest in the Piraeus port. PMF and CAMx estimations for the net shipping contribution to fine particulate matter (PM₂.₅) in the Piraeus passenger port area s
