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.
