Abstract

Direct determination of cadmium and lead in aerosols in the Zasavje region in Slovenia employing electrothermal atomic absorption spectrometry R. Milacic, F. Dolinsek Department of Physical and Environmental Chemistry, 'Jozef Stefan' Institute, University of Ljubljana, Jamova 39, 61000 Ljubljana, Slovenia ABSTRACT Investigations of air pollution were carried out in Trbovlje, Zagorje and Hrastnik, three towns in the Zasavje urban region in Slovenia with its dense industry. This region has a typical geographic location in small, closed side valleys of the Sava river. Special pumps were equipped with a Nucleopore-Costar polycarbonate membrane filters (pore size 0.4 j^m) to determine cadmium and lead in respirable (<2.5 urn) and inhalable (2.5-10 jam) aerosols. These two elements were measured continuously for two years. Filters were collected every 10 days. Cadmium and lead were measured in those filters employing slurry electr
