Carbonaceous Aerosols Over the Mediterranean and Black Sea
The role of carbonaceous material (organic and elemental carbon) in the Mediterranean and Black sea atmosphere is yet to be unraveled. To fill this gap the present work is focused on the study of carbonaceous aerosols over the Mediterranean and Black Sea. Thus, aerosol samples were simultaneously collected at a remote site in Greece (Finokalia, Crete), a highly populated urban (Istanbul), a remote (Imbros) and two rural sites in Turkey (Sinop, Erdemli). Approximately 1,200 aerosol samples were collected and analyzed for Organic and elemental carbon (OC and EC), as well as water-soluble organic carbon (WSOC). Their seasonal variation, the factors controlling their variation and their relative contribution to aerosol mass is presented and thoroughly discussed. More specifically, organic matter constitutes a significant part of the total PM10 mass (21–33% of Particulate Organic Matter and 2–11% EC). The percentage of WSOC ranges from 37% to 40% of the OC for the four remote and rural regions, while in Istanbul constitutes 27% of OC and 10% of the total PM10 mass. Correlations with potassium and sulfate showed that the sources of organic matter in Istanbul are mainly due to the anthropogenic activities, while in rural and suburban areas to long range transport and biomass burning.
