Abstract:
In this study are presented the preliminary results regarding the
distribution and migration of Cd and Pb in urban soils from industrial zone
of Iaşi city. The studied soils are strong antropized and present radical
modifications of lithology, mineralogy and chemistry. The Cd content varied
between 0.09-1.36 µg/g, and the lead content between 25.83-186.73 µg/g.
The experimental results have evidenced the existence of some abnormal
distributions of cadmium and lead in studied soils, and association ways with
soils components less characteristic for these metals, respectively. The
characteristic for studied soils is high accumulation probability of Cd and
Pb, as mobile species with high toxic potential.
