Phytoremediation
nounPronunciation: /ˌfaɪtoʊrɪˈmiːdiˈeɪʃən/
The use of living plants to extract, sequester, or detoxify contaminants from soil and groundwater in reclaimed mine sites. Plants absorb metals and organic pollutants through their root systems, accumulating them in biomass that can be harvested and managed.
Plain English
Using plants to remove or neutralize pollution from abandoned mine sites.
Etymology & History
Usage
"Phytoremediation using native willow species successfully reduced copper concentrations in the restored wetland area."
Style guide notes: Distinguish phytoremediation from phytostabilization; phytoremediation implies contaminant removal, phytostabilization implies immobilization.
