Impact/Purpose:
this work advances our understanding of the way nanomaterials are transported in surface waters following their release
Description:
The unique properties of nanomaterials have resulted in their increased production. However, it is unclear how nanomaterials will move and react once released to the environment One approach for addressing possible exposure of nanomaterials in surface waters is by using numerical, mechanistic fate and transport models. The currently available environmental fate models that have been developed for traditional contaminants are limited in their ability to simulate nanomaterial behavior in the environment. We are currently redesigning WASP toincorporate nanomaterials as a state variable and incorporating algorithms to address the processes governing nanomaterials in aqueous media. This presentation will discuss the processes necessary to simulate nanomaterials in surface waters, the processes being incorporated into the updated WASP, how the updated WASP will compare to the current WASP, and the projected studies and simulations to investigate how nanomaterials move through surface waters.
