Phytoremediation of Selected Pharmaceuticals by and their Phytotoxicity to Aquatic Plants

Abstract Details

2014, Master of Science, University of Toledo, Biology (Ecology).
Pharmaceutical and personal care products (PPCPs) are a class of “emerging” contaminants that have received increased concern. The overall objective of this research was to evaluate the phytoremediation of three pharmaceuticals (Diltiazem, Diphenhydramine and Sulfamethoxazole) by aquatic plants (Azolla caroliniana, Lemna minor, and Pistia stratiotes). The removal efficiencies of selected pharmaceuticals in aquatic systems depended on the physico-chemical properties of the pharmaceuticals as well as the plant species being used. Plant species in this study were tolerant towards the pharmaceutical concentrations as high as1000 µg L-1 by the end of the exposure time despite the decrease in RGR of A. caroliniana in initial exposure time (day2). Pharmaceuticals other than SMX were rapidly removed from the nutrient solution by these plants. For instance, DIL was almost completely removed by L. minor after day 2. This study suggests that selected plants can play an important role in removing the selected pharmaceuticals from water and can thus contribute to enhance the phytoremediation of pharmaceutical in wetland systems.
