Summary:
This Thesis was undertaken as a partial fulfillment of the requirements for the
Postgraduate Program of Studies "Applied Environmental Geology" of the
Department of Economic Geology - Geochemistry of the Department of Geology at
the University of Athens, Greece.
The major objective of this thesis has been through a series of specific single
extractions, the assesment of the environmental availability of 9 potentially
hramful elements, such as Pb,Cd,Zn,Ni,Cr,Cu,As,Mn and Co, natural or
anthropogenic, to urban top soils of the basin of Athens.
Data who were extracted after the statistical analysis, showed that the
anthropogenic elements (Pb,Cd,Zn,Cu) have much more environmental availability
of geogenic elements (Cr,Ni,Co,As,Mn). The pseudototal concentrations of
anthropogenic elements is the main factor controlling their availability while
amorphous Fe oxides on anthropogenic elements and amorphous oxides of Mn and
organic carbon for geogenic, are the geochemical soil factors who affect the
availability.
