To evaluate the ecological risk of emerging contaminants of concern such as engineered nanomaterials (ENMs), it is critical to test them using exposure scenarios that are as realistic as possible. To that end, I study the environmental fate and bioavailability of ENMs in aquatic ecosystems following environmentally-relevant exposures, including aspects such as their aggregation and sedimentation behavior, transport, bioaccumulation, uptake kinetics, biodistribution and clearance. With collaborators at CRASR and outside of Baylor at the Center for the Environmental Implications of NanoTechnology, we have conducted several mesocosm and microcosm experiments of simulating streams and wetlands of different scales, with varying exposure durations and aquatic taxa involved, testing ENMs with differing properties.
