ABSTRACT
Phytoremediation is a viable, effective, and economically attractive technology that uses plants to remove chemical contaminants from soil and groundwater. A major munitions contaminant, TNT (2,4,6-Trinitrotoluene) can be remediated by several plants such as Myriophyllum aquaticum (Parrot Feather), and Catharanthus roseus. This study focuses on screening plants that have natural antioxidant phytochemicals for their ability to remediate TNT, and heavy metals from contaminated water sources, groundwater and soil. Three kinds of bell peppers, Capsicum frutescens (green, red, and yellow), which contain both the antioxidant phytochemicals (carotene and vitamin C) and tomato, which also contains vitamin C, were tested to confirm their antioxidizing and remediation abilities respectively. Results for remediation abilities were analyzed by HPLC (High Performance Liquid Chromatography). Results also suggested that plants which had antioxidant properties were also able to remediate TNT and heavy metals effectively, thereby suggesting a possible correlation between antioxidant and phytoremediation abilities of the plants studied.
