Determination of Heavy Metals in Wet Deposition of Athens

The concentrations of ten industrial metals (Pb, Cd, Ni, As, Cr, Zn, Fe, Cu, Al and Mn) in 20 samples of
rainwater collected at the station of Athens University Campus (AUC) during the cold period 1/10/97 -
31/3/98 were determined. In general, low concentrations were observed. The Spearman correlation coefficients
for different metals were calculated in order to reveal common sources. Principal Component
Analysis (PCA) was used to identify the factors that affect the presence of metals in rainwater.
