- •
Concentrations of As, Cd, Cu, Pb and Zn in soils in a mined area, Western Thailand were analyzed.
- •
High levels of As and Pb occur in soils including some soils distant from mine sites.
- •
Concentrations of Cd, Pb and Zn are highest in surface soil.
- •
SEM/EDS results confirm that Pb is associated with clay minerals and Fe/Mn oxides.
- •
The abandoned Pb-Zn mining sites are “hot spots” of soil contamination.
