Browse all Theses and Dissertations

With the ubiquitous burst of nanotechnology, silver nanoparticles (AgNPs) have become indispensable in numerous industrial, medicinal, and research applications. Consequently, AgNPs have been alarmingly disposed into subsurface water increasing the risk of human and environmental exposure. While mechanisms of AgNP cytotoxicity have been reported, research studies on AgNP transport in subsurface water are needed, according to U.S. Environmental Protection Agency (EPA). The main goal of this study was to investigate the environmental fate and transport of widely-used Creighton colloidal AgNPs in a laboratory transport system simulating a porous, saturated groundwater aquifer. To achieve this, a large volume of AgNPs was …
