How are poplar trees being used to remove the toxin TCE from the soil at J-field?
What will be an ideal response?
In the case of organic toxins such as TCE, the best phytoremediation strategies use plants with biochemical pathways that break down the compounds to less toxic molecules. So, in 1996, the Army planted poplar trees that cleanse groundwater by taking up TCE and other organic pollutants in it. The trees' roots take up water from the soil. Along with the water come nutrients and chemical contaminants, including TCE. Although TCE is toxic to animals, it does not harm the trees. The poplars break down some TCE, but they release most of the toxin into the atmosphere.
