To inform the EPA
Description:
The ever-increasing use of engineered nanomaterials leads to increased concerns of human and ecological exposure to these materials. EPA’s regulatory role for nanomaterials creates a significant need for understanding the fate and transport properties of nanomaterials in environmental systems and the associated mechanisms governing these processes. One of the key research needs is the elucidation of physical and chemical characteristics of nanomaterials that dictate their transport and fate in the environment. Our research focuses on the major processes/properties of nano-size C60 in environmental aqueous systems. Also investigated is the formation kinetics of aqueous suspensions, particle-particle interactions, particle-surface interactions, and Lewis acid-base interactions of these nanomaterials. The results shed light on their environmental fate and transport and potential ecotoxicological impact.
