Hyperaccumulators are able to grow in contaminated soil and remove large amounts of toxic metals from the enviroment. The plants themself can later even be used to extract said toxic metals like quicksilver or lead.
Tbh i just like quicksilver more because it is phonetically near the german word for it Quecksilber. I am aware that quicksilver is archaic but i kinda just dont care
in chernobyl truffle fungi were hyperaccumalators of radioactive metals, they found that out when they examined why the wild boar had higher than normal amount of the elements.
