Phytoremediation, in its broadest sense, means using plants for the clean up of unwanted contaminants from soil. The technology has been recognized as an inexpensive, environmentally friendly remediation method worthy of serious consideration, particularly when compared to remediating soils by excavation and burial at an enormous cost. There are various processes associated with phytoremediation e.g., phytoaccumulation, phytoextraction, phytovolatilization, phytostabilization, phytofiltration, and phytodegradation. Depending on the contaminant and location, e.g., field site, waterway, industrial or urban setting, one or more remediation processes may be more feasible for a biological cleanup using living plants. For this paper, we will report on our long-term experiences using phytoextraction and -volatilization on a natural contaminant - selenium (Se) under field conditions. Although these reported field experiences revolve around Se, some of the same concerns associated with sustainable field phytoremediation e.g., plant selection, crop rotation, soil chemistry, insect and wildlife infestation, agronomic practices, costs, effectiveness, product utilization and public acceptance, need to be addressed for effective phytoremediation of any contaminant in either an agricultural or urban setting.
