Abstract:  Engineered nanomaterials (ENMs) undergo a variety of transformations (e.g. sulfidation, interaction with organic matter and proteins, dissolution) that affect their environmental fate, exposure potential, and toxicity.  Cataloging the breadth of these transformations in environmental and biological media, and characterizing the properties and toxicity of the transformed nanomaterials is essential to accurately predicting the environmental risks of ENMs.  This lecture will present work across the Center for Environmental Implications of Nanotechnology characterizing ENM transformations and fate in the laboratory and in real complex environments.  The impacts of these transformations on metal bioavailability and ecological effects, and the role of system complexity and feedback loops on ENM fate and effects are also presented.
