The Odnevall (Wallinder) group: Corrosion/surface science towards effects on human health and the environment – an on-going and future research strategy

The research approach involves multianalytical and interdisciplinary studies to assess corrosion and surface phenomena and mechanisms, and their relation to metal dispersion, bioaccessibility, bioavailability, metal speciation and toxicity. The ultimate goal of this highly interdisciplinary research approach is to increase the general knowledge and understanding of the link between surface reactivity, material properties and environmental fate and health aspects of metal dispersion from metals and alloys used in a large variety of applications ranging from external buildings and applications, to food related utensils and surfaces, to implant materials and to metallic nanoparticles in consumer products.

The research team performs world-leading studies on atmospheric corrosion and on the diffuse dispersion of metals from outdoor construction materials and their environmental fate. Another main research direction involves the characterization of surface and bulk properties of nano- and micron-sized metal particles, surface reactivity, surface-protein interactions, metal release and speciation in biological media, and their links to toxicity,
as well as colloid stability and mobility and environmental fate of NPs.

While focusing on fundamental questions are several research projects related to industrial problems and run in close collaboration with national and international industry and industrial organizations. On-going research activities have further strong implications for the classification system of chemicals within the European Union, REACH, as well as for environmental and health risk assessments of metals and alloys.
