Abstract
The Center for the Environmental Implications of NanoTechnology (CEINT) is engaged in research that seeks to elucidate relationships between properties of nanomaterials and their environmental behavior. This presentation provides an overview of activities in CEINT and illustrates the methodology being applied to a wide range of nanomaterials in developing a framework for nanomaterial risk assessment. In this presentation the examples of nano silver and C60 are used to illustrate how this collaborative research effort is organized. Nanomaterial transport and relative affinity of nano Ag for solid phases is discussed as well as possible transformations of nano Ag in the environment and the impacts that these transformations may have at the scale of cells, organisms and ecosystems. The role of aggregation in modifying nanoparticle reactivity is discussed in the context of the fullerene C60.
