5. Conclusions
Field sampling and chemical monitoring of soil pore water in the
major abandoned mining district of Iglesiente (SWSardinia) confirmed
that pore water is a rapid and easy method to collect reliable information
on the potential risk of a contaminated soil.
Soil porewaters chemistry in the studied sites reflects themineralogy
of the local soil, and suggests an approach to equilibrium with
coexisting solid phases. This aspect permits to easily evaluate which
minerals are likely responsible for controlling (toxic) element mobility.
With respect to laboratory tests on metal mobility, the analysis of
pore water permits to evaluate trace elements mobility, and the
