Question for Peter McCoy- remediation of heavy metals

Hey, Peter. I like your vid on cigarette butt remediation, and I'm wondering if there are any chemicals that you can think of to act as a precursor to train oyster mushrooms to remediate inherent pesticide and chemical buildup on old orchard sites? There are a lot of old orchards around this area, and its hard to trust fruit from a tree that is old enough to have most likely been sprayed or dusted with things like lead arsenide and calcium arsenate. What are your thoughts on heavy metal remediation?

Hi Ben
I have outlined some of these principles in other threads and suggest you check those notes out. But, yes you can "train" fungi to remediate chemicals through a series of steps. Metals are much harder to deal with due to the nature of inorganic chemistry and the complexity of soil conditions.
