Bioavailability of Toxic Elements in Mine Spoils and Contaminated Soils
Metals and metalloids occur in mine spoils and contaminated soils in a number of forms, of which only the species present in soil
solution are available for direct plant uptake. These species may be toxic at excessive concentrations to vegetation employed in
rehabilitation.
- The overall objective of this project is to develop accurate methods for the assessment of bioavailability/phytotoxicity of
elements such as Cu, Cd and Zn etc.
- Preliminary evaluation of the coupled liquid chromatography/mass spectrometry (LC/MS) technique has indicated that this
approach has considerable promise in the qualitative aspect of the study of elemental speciation and bioiavailability
in soil solutions.
