Aerosol samples have been collected in urban air by means of Nuclepore
polycarbonate membrane filters from October 29, 1991 to October 17, 1
994. Parallel sampling has been made from September 15, 1993 to Octobe
r 17, 1994 with a stacked filter unit, too. The elemental composition
of the samples was determined by PIXE. Yearly, winter and summer avera
ges of elemental concentrations have been calculated together with enr
ichment factors. Principal components analysis has derived four factor
s, elemental source profiles and contributions of various sources.
