A Berner low pressure impactor was used to collectsize-segregated aerosol samples at Finokalia, located onthe north-eastern coast of Crete, Greece during July 2000 andJanuary 2001. Several samples were also collected during thesummer campaign aboard the research vessel “AEGAIEO”in the Aegean Sea. Gravimetric analysis and inversion techniquesyielded daily PM1 and PM10 mass concentrations.The samples were also analysed by PIXE giving the elementalsize distributions of Al, Si, K, Ca, Ti, Mn, Fe, Sr, S, Cl,Ni, V, Cu, Cr, Zn, and Pb. The crustal elements and sea-salthad a unimodal supermicron size distribution. Sulphur wasfound predominantly in submicron fractions. K, V, and Niexhibited a bimodal distribution with a submicron mode producedby forest fires and oil combustion. The anthropogenicelements had broad and not well-defined distributions. Thetime series for PM1 and PM10 mass and elemental concentrationsshowed both daily and seasonal variation. Highermass concentrations were observed during two incursions ofSaharan dust, whilst higher concentrations of S, Cu, Zn, andPb were encountered in samples collected in air masses arrivingfrom northern Greece or the western coast of Turkey.Elevated concentrations of chlorine were found in sampleswith air masses either originating above the Atlantic Oceanand arriving at Finokalia via western Europe or recirculatingover the western coast of the Black Sea.
