Abstract. A Berner low pressure impactor was used to collect size-segregated aerosol samples at
Finokalia, located on the north-eastern coast of Crete, Greece during July 2000 and January 2001.
Several samples were also collected during the summer campaign aboard the research vessel
"AEGAIEO" in the Aegean Sea. Gravimetric analysis and inversion techniques yielded daily PM1 and
PM10 mass concentrations. The samples were also analysed by PIXE giving the elemental size
distributions of Al, Si, K, Ca, Ti, Mn, Fe, Sr, S, Cl, Ni, V, Cu, Cr, Zn, and Pb. The crustal elements
and sea-salt had a unimodal supermicron size distribution. Sulphur was found predominantly in
submicron fractions. K, V, and Ni exhibited a bimodal distribution with a submicron mode produced
by forest fires and oil combustion. The anthropogenic elements had broad and not well-defined
distributions. The time series for PM1 and PM10 mass and elemental concentrations showed both
daily and seasonal variation. Higher mass concentrations were observed during two incursions of
Saharan dust, whilst higher concentrations of S, Cu, Zn, and Pb were encountered in samples collected
in air masses arriving from northern Greece or the western coast of Turkey. Elevated concentrations of
chlorine were found in samples with air masses either originating above the Atlantic Ocean and
arriving at Finokalia via western Europe or recirculating over the western coast of the Black Sea.
