Airborne material collections and their chemical composition over the Black Sea

The chemical composition of the Black Sea aerosol was studied during the July 1992 CoMSBLACK 92 cruise on board R/VBilim. It has been shown that the chemical composition of the Black Sea aerosols can change very rapidly in accordance with changes in the wind regime. The influence of the Saharan desert particles can alter the elemental concentrations of trace metals. The result has been summarized on Enrichment Factor diagrams to permit comparison with previous and future studies. The atmospheric input of oxidized nitrogen (NO3+NO2−N) can reach 13% of the total inorganic nitrogen input of the Danube. Lead (Pb) input reaches 39% of this riverine input. Such loads can play an important role in the present state of the sea.
