Short summary
A measurement campaign in Toulon's port in 2021 showed a strong decrease in sulfur-related emissions after IMO2020, while black carbon, organics and polycyclic aromatic hydrocarbons (PAHs) remained at previous levels, as confirmed by their emission factors. Source analysis indicated that ships contributed notably to organic aerosol and alkylated PAHs, and dominated ultrafine particles. These results support continued monitoring as the Mediterranean becomes a sulfur emission control area in 2025.
