ZnO particles synthesised with size tuned from 60nm to 550nm.
We are interested in studying if/how physico-chemical properties of nanoparticles may affect their reactivity and potential toxicity. Specifically, we investigate how particle size affects solubility and agglomeration behaviour in environmental and biological media. We are also interested in studying the bioavailability and in detection of nanoparticles in the environment and are currently exploring the use of stable isotope tracing technique.
We work with isotopically labelled ZnO nanoparticles using Zn67 and Zn68 as labels as well as with CuO nanoparticles enriched with Cu65 and Ag nanoparticles enriched with Ag109. The particles are being tested in eco-toxicity studies looking into the potential pathways of nanomaterials into aquatic food chains. To this end we work in collaboration with USGS http://wwwrcamnl.wr.usgs.gov/tracel/, Department of Zoology at NHM (Trace Metal Biology Laboratory) and Imperial College London http://www3.imperial.ac.uk/earthscienceandengineering/research/magic

Historical mining sites present a very interesting environment to study geochemistry of metal contaminants in soils and waste materials. Some of the toxic elements present on such sites have been naturally immobilised - e.g. arsenic by sorption onto Fe oxides and precipitation of iron arsenates. Other elements are still leaching out creating a potential hazard for surface/groundwater contamination. On some of these sites extremely high concentrations of metals (thousands of mg/kg) are found in soils and waste materials, yet they support plant growth - very interesting metal resistant plant communities developed. Investigations are under way into metal immobilisation on such sites using in situ metal fixation with soil additives and phytoremediation.
