TRACE-ELEMENT COMPOSITION OF THE BLACK-SEA AEROSOLS

Shipboard aerosol samples collected from the Black Sea atmosphere were analysed for Al, Ca, Mg, Ti, V, Cl, I, Mn and Na, by using instrumental neutron activation technique. Concentrations of elements were intermediate between continental rural sites and remote marine sites. Back-trajectory calculations showed a general easterly flow. Observed enrichments of elements can be attributed to crustal, marine and anthropogenic sources. The (Mn)ner/(V)ner ratio showed differences with trajectory groups. The average (Mn)ner/(V)ner ratio was more representative of European sources.
