Phytoremediation is a general term
used to describe the use of green
plants to clean up contaminated
soils, sediments, or water.
Phytoremediation Advantages:
Costs much less than traditional

Plants can be easily monitored to
ensure proper growth
It is the least destructive method of
remediation because it utilizes
natural organisms and solar power
via photosynthesis
