I am looking for information about where different types of plants absorb and retain heavy metals and other toxins.
I would like to compile a list of edible plants that are safe to propagate and consume despite soil contamination. This could include plants that absorb toxins but deposit them in isolated areas. I have been told, for example, that tree fruits can be planted in lead contaminated soil, because lead never rises high enough in trees to wind up in their fruits. Or, if you know of such a list already out there, I would love to see it! I think that lead is the most common toxin in many urban areas, so I am particularly interested in where plants deposit lead, but I would appreciate information on how/where they hold onto other toxins as well. Thanks for your help, Ben
