Transgenic plants remove more selenium from polluted soil than wild plants, new tests show
... In contrast, they say that using plants to remove contaminants
- a process called phytoremediation -- provides one of the most cost-effective methods of cleaning polluted soil available. "Phytoremediation can help clean up the selenium, but the thing that's holding people up from using plants more widely is that...

Plants become green Mr. Clean to combat toxic messes
...ains that phytoremediation using plants to remove contaminants
from the soil is evolving. In the early stages of this technology, plants were used like sponges, soaking up toxic substances so they can be safely discarded. The next step, Rugh says, is plants that act like a green Mr. Clean, with roots that make...
