AGROCHEMICAL MODIFICATIONS IN ZLATNA SOILS UNDER HEAVY METAL POLLUTION
AbstractThe paper presents a synthesis of the agrochemical modifications determined by
heavy metal pollution in the Zlatna area- Alba county.
These modifications present the contamination effects of soil plant contamination
with heavy metals (Pb, Cd, Cu, Zn), on the background of acidification-dealkalinization processes determined in the soils through excessive industrial emissions with sulfur oxides and sulphides of metals. At the end of the polluting activity (years 1998-2001) soil degradation through heavy metal pollution involved chemical and physical phenomena that exerted their influence on soils for several decades, diminishing the productivity of agroecosystems and even removing them from the agricultural circuit, for their recovery
and ecologic reconstruction.
