Simulating the Environmental Fate and Transport of Graphene Oxide Nanoparticles and Their Major Phototransformation Product in Surface Waters: ORD-024619

Description

There has been growing interest in simulating the fate and transport of engineered nanomaterials in the environment. The Water Quality Analysis Simulation Program (WASP) is one of the most widely used water quality models and has recently been upgraded to WASP8. WASP8 incorporates the algorithms to simulate the fate and transport of nanoparticles in surface waters. This study simulates the fate and transport of graphene oxide (GO) nanomaterials and their major phototransformation product, photoreduced graphene oxide (rGO), for Brier Creek, GA, USA. We specifically explored the influences of three important processes on the fate and transport of GO: (1) light attenuation, (2) phototransformation, and (3) heteroaggregation, and simulated their distributions in the river, including the water column and sediment. This dataset is associated with the following publication: Han, Y., C. Knightes, D. Bouchard, R. Zepp, B. Avant, H. Hsieh, X. Chang, B. Acrey, M. Henderson, and J. Spear. Simulating graphene oxide nanomaterial phototransformation and transport in surface water. Environmental Science: Nano. RSC Publishing, Cambridge, UK, 6: 180, (2019).
