lead levels in wild greens ("weeds") that grow in your yard?

Would you could you in a box? would you could you with a fox?

my soil samples (UMass Amherst) --

front 359.5
side 448
back 640.2
little patch in the back that may have been bulldozed in from the nieghbor's many years ago but H. is blind so she doesn't know for sure 379.8

Would you eat lambsquarter from this as a regular thing? ( ate it once, haven't died. Ok, I made a pesto from it and ate that for several days. strangely no one else really went for it. it was good--walnuts, from the dumpster, cheese, also from the dumpster, and lambsquarter/fat hen if you're German and olive oil)

What about "you don't have a surplus of lead problem, you have a lack of ____ problem?"

Is the lead in my soil actually bio-unavailable? (inert form--pyromorphite)? is it possible to determine? will me lead test from UMAss tell me this since it only tells teh total lead they find in the soil?
Thanks!

Would eating more bone broth with your meal bind the lead in the greens into (inert) pyromorphite?

Is it not possible to get lambsquarters or equivalent greens from a location not contaminated with lead? That would be my first impulse rather than trying to bind the with bone broth. But the specific chemistry is beyond me. Good luck.
