Model Predictions of Metal Speciation in Freshwaters Compared to Measurements by In Situ Techniques

In-situ metal speciation in soils using synchrotron based techniques

Contamination of the environment resulting from anthropogenic activities such as mining, smelting and agriculture is of great public and political concern. As such, a greater understanding of the mobility, bioavailability and long-term fate of the materials resulting from these activities is needed in order to make more accurate decisions when devising remediation and legislative strategies. To...
