- Phytoremediation (a lecture)
- Use plants to "vacuum" heavy metals from the soil through their roots
- Certain species have the ability to extract elements from the soil and concentrate them in the stems, shoots, and leaves
- The unique plants must be able to tolerate and survive high levels of heavy metals in soils-like zinc, cadmium, and nickel.
- These plants possess genes that regulate the amount of metals taken up from the soil by roots and deposited at other locations within the plant.
- Some contaminants also changed into safer gases as plant traspires.
