- Abstract:
- Natural aquatic colloids are vital in determining the fate and behaviour of trace metals in the environment. The exact role of colloids will be determined by their physico-chemical structure on a macromolecular scale. This proposal will investigate colloidal structure in selected freshwaters though the novel coupling of state-of-the-art analytical techniques such as flow field-flow fractionation and various force and electron microscopy methods (ESEM, AFM and TEM). Measurements will be performed on individual colloids of size, diffusion coefficient and surface area. In addition, two-dimensional maps of elemental concentration at the nm scale will be produced. Bulk measurements of major and trace elements as a function of size will also be performed. The measurements will give new information on the structure of colloids providing greater understanding of their role in trace metal speciation.
