Characterization of carbonaceous aerosols over the Northern Adriatic Sea in the JERICO-NEXT project framework
Abstract The coastal aerosol represents a complex mixing between sea spray aerosols locally generated at the sea surface and a component generated by natural and/or anthropogenic sources on the nearby land. The aim of this paper is to study the atmospheric concentrations of carbonaceous compounds as measured in the coastal zone of the Northern Adriatic Sea between April 2017 and April 2018. The results show a quite large contribution of carbonaceous compounds, even when the sampled air mass is predominantly maritime. Although it is generally assumed that 70% and 90% of bulk organic carbon (OC) and elemental carbon (EC) concentrations, respectively, are found in the fine mode, we observed higher OC and EC concentrations in the coarse fraction (up to about 37% and 25%, respectively). This confirms the occurrence of mixing between anthropogenic matter and sea spray, mainly composed of coarse aerosol particles, during the atmospheric transport over the Mediterranean basin.
Highlights Organic and elemental carbon size distributions measured at an off-shore platform near to an industrial coastal area. Thermo-optical analysis performed on impactor samples by ad-hoc solutions. Large organic and elemental carbon concentrations were measured. Occurrence of external mixing between sea spray and anthropogenic matter.
