Rhizosphere Interactions Between Copper Oxide Nanoparticles And Wheat Root Exudates In A Sand Matrix; Influences On Bioavailability And Uptake, Paul Mcmanus
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Copper oxide nanoparticles (CuO NPs) are extremely small particles (less than 1 nm in one or more dimension, or one billionth (10-9) of a meter) used in a diverse range of industries. They have been shown to travel through water systems, and like pharmaceuticals, can end up in wastewater treatment plants and then be land applied as biosolids, where crops are grown for animal consumption, potentially leading to food chain accumulation.
Cu is an essential micronutrient for plants, but is phytotoxic at higher concentrations. CuO NPs present an increasingly real environmental threat to agriculture in soils treated with …
