Hyperaccumulator
nounPronunciation: /ˌhaɪpərˈækjəmjəleɪtər/
A plant species capable of accumulating and tolerating extraordinarily high concentrations of heavy metals in above-ground tissues, typically defined as containing more than 1,000 mg/kg of a particular metal. These botanically specialized organisms are critical for phytoremediation strategies in contaminated mine sites.
Plain English
A plant that can absorb and tolerate very high amounts of toxic metals without dying, used for cleanup.
Etymology & History
Usage
"The reclamation biologist identified several hyperaccumulators of cadmium native to the region for planting on the abandoned smelter site."

Frequently Asked Questions
How do hyperaccumulators tolerate high metal levels?
These plants have specialized cellular mechanisms that chelate metals, compartmentalize them safely, and exclude toxicity.
What happens to harvested hyperaccumulator biomass?
Biomass is typically incinerated for metal recovery, landfilled, or composted depending on metal type and concentrations.
