The pharmaceuticals acetaminophen, sulfamethoxazole, and carbamazepine, and herbicide atrazine are among the most highly manufactured compounds in the world and are frequently detected in the aquatic environment. Much uncertainty exists regarding the impacts of the pharmaceuticals on non-target aquatic resources, while more is known about atrazine. Reduction of residues of each chemical in surface water will reduce the exposures that organisms experience in the surface water environment, thus reducing unknown risks. This project evaluated the potential use of two aquatic plant species (Acorus gramineus and Canna hybrida ‘Orange Punch’) for reducing concentrations of the chemicals in water. Concentrations of each contaminant in solution were reduced in the presence of the plants after 14 days of exposure, in (acetaminophen 64–100%, atrazine 32–51%, carbamazepine 26–49%, sulfamethoxazole 41–60%). Results indicate that these plants have potential for reducing concentrations of these chemicals in surface water, but that plant- and chemical-specific properties prevent making generalizations regarding the extent and pathways for dissipation.
