What do they do with the heavy metals once removed? Or do people collect the isopods?
It stays in their bodies then goes back to the environment when they die. From my understanding they're less useful for removing heavy metals and like op states they're more useful as bio indicators. Basically collect a bunch and test how much heavy metal they have to determine general contamination in the area. They would probably be really difficult to remove at quantities that actually decontaminate soil or water
The real pros for heavy metal removal are oysters. Easy to farm, they collect heavy metals, carbon, and other stuff in their shells, the shells can be disposed of at scale, and they're arguably vegan
Try planting oysters in the soil though, lmao. You are right all around; no one is using isopods to remediate. You can use some plants, like sunflower, and I believe hemp, but you have to remove them from the system - it isn't alchemy.
I'll put one next to the hotdog tree I planted.
The writing is barely legible
