Heavy Metal <strong>Stress</strong><br />

7. CONCLUSION<br />

The success <strong>of</strong> phytoremediation will require an improved underst<strong>and</strong>ing <strong>of</strong> the biological<br />

processes involved in metal acquisition, movement across plant cells within a<br />

plant, shoot accumulation, <strong>and</strong> metal detoxification in both metal hyperaccumulator<br />

<strong>and</strong> nonaccumulator plants. Once our knowledge <strong>of</strong> these intricate processes is further<br />

enhanced, we will be able to fully take advantage <strong>of</strong> plants for phytoremediation <strong>of</strong><br />

numerous <strong>and</strong> vast areas <strong>of</strong> agricultural l<strong>and</strong> <strong>and</strong>/or natural habitats.<br />
