Fate and transport of titanium dioxide through freshwater ecosystems


EMSL Project ID
22690

Abstract

This project will identify and quantify titanium dioxide (titania, TiO2) nanoparticles and its subsequent mass balance in environmental media (i.e., water, sediment and benthic/sediment dwelling invertebrates) to monitor the fate and transport of nanomaterials in a bench-scale mesocosm system. Characterization of nanomaterial partitioning and complexation in water, sediment, and tissue media will be performed using inductively coupled plasma mass spectrometry (ICP-MS) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), respectively. These data sets will build the foundation for future use in fate and transport of other nanomaterials in different water systems (fresh, estuarine, and marine) and in building an empirical model that investigates environmental fate and transport and ecological impact of nanomaterials.
