TIL about Hyperaccumulators, a low cost way of recyling contaminated soil

en.m.wikipedia.org

Hyperaccumulator - Wikipedia

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.

TIL quicksilver is another term for mercury
- 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
  
  I'm just surprised I'd never heard it before. In the same vein, I prefer to use natrium over sodium.
This is an evolutionary strategy for them to occupy niches that other plants can't, this giving them a competitive edge. Some other metal tolerant plants don't hyper accumulate, and have pathways to selectively uptake what they need without poisoning themselves.
Hyper accumulators take up everything and then just store it in the vacuoles of their cells to isolate the metals.
Importantly, when the plants die, the metals are re-released, so if you're phyroremediating you have to harvest them and then dispose of them in a landfill.
Finally, hyper accumulators can pose a risk to wildlife that might browse on them, whereas metal tolerant plants may not
Tobacco and cannabis are both bio-accumulators, so it's important to smoke properly grown bud.
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.
- Fungi in general. They are the filters of nature.
- Well thats some weird knowledge do you have a source maybe?
quicksilver
You mean mercury?
- Still called quicksilver in some English speaking spots.
- I believe they were referring to one of the Maximoff twins.
