Abstract:
The dusts resulted from the metallurgic activities have a great impact
on the soil, by the high contribution in heavy metals. These elements are
accumulated, especially in the superior layer of the soil, from where they are
absorbed by plants, and after that the metals overtake in high concentration
in the food chain, even in human body. The impact of metallurgic activities
on the soils was established by the heavy metals concentration which, in a
high range, affects the soil quality. The acquired concentrations have
maximum values which get over the alert limit for soils affected by the
sedimentable dusts. The concentration level of heavy metals in the soils,
influenced by the metallic dusts, range of 89,51-420,86 mg/kg dry soil for Cr;
131,8-600,39 mg/kg dry soil for Cu; 132,79-870,33 mg/kg dry soil for Zn;
71,99-294,28 mg/kg dry soil for Pb, respectively between undetectable limits
and 11,2 mg/kg dry soil for Mo.
