Abstract/Contents

Abstract: Water reuse is increasingly important for meeting future water supply needs in arid and semi-arid regions. For this reason, understanding the fate and transport of trace contaminants in reclaimed water for irrigation is necessary to ensure ecological and human health, as well as for gaining public acceptance for the future growth of water reuse. Furthermore, drinking water aquifer augmentation via stormwater capture and recharge is being proposed. This study aims at fundamental understanding of the uptake and fate of chemicals of emerging concern (CECs) in vegetative systems. In the first part of this project, the hydroponic uptake and transport of selected polar organic contaminants are studied with the model plant Arabidopsis thaliana. Within this system the metabolic fate of CECs is being investigated. Since initiation of this project, we have observed uptake and evidence of metabolism of some trace polar organic pollutants. Specifically, we have discovered that benzotriazole is rapidly taken up and metabolized in-planta, and we report newly discovered transformation products. Perfluorochemicals do not degrade, but are partitioned in the plant tissue based on their physiochemical properties.
