Hyperaccumulator Species
nounPronunciation: /ˌhaɪpərəˈkjuːmjəleɪtər ˈspiːʃiːz/
Plants capable of accumulating and tolerating extraordinarily high concentrations of specific heavy metals or other contaminants in their above-ground tissues without exhibiting toxicity symptoms. These specialized organisms are critical tools in phytoremediation strategies for mine sites.
Plain English
Plants that can absorb and store large amounts of heavy metals without being poisoned.
Etymology & History
Usage
"Scientists identified several hyperaccumulator species native to the region that could reduce zinc concentrations in the abandoned mine soil."

Frequently Asked Questions
Which plants are hyperaccumulators?
Examples include Thlaspi caerulescens (zinc/cadmium), Alyssum lesbiacum (nickel), and various Asteraceae family members.
How are hyperaccumulators used in reclamation?
They are cultivated on contaminated sites where they absorb metals; biomass is then harvested and safely disposed or recycled.
Why Test Candidates on This?
Hyperaccumulator species identification and application is tested in advanced ecological restoration and botanical reclamation courses.
