phytoremediation [n. FY-toe-ruh-mee-dee-AY-shun]
----------------------------------------------------------------------
Phytoremediation is the use of living plants to remove toxic
substances from soil, water, or air. It's a relatively new concept
that takes advantage of plants' natural ability to absorb and process
toxins.
This word has two parts. Phyto- is based on the Greek phuton (plant),
which comes from phuein (to cause growth). There are many other words
using this root, including these:
epiphyte: plant that grows on another plant
phytography: science of describing plants
phytophagous: feeding on plants
The second part can be a word by itself. Remediation is solving a
problem by correcting a fault or deficiency. It's from the Latin
remedium (cure), from re- (again) plus mederi (to heal). Related
words include remedy, medicine, and medicate.
