and one interesting case is with Cucurbits, which will pick up certain
chlorinated hydrocarbon pesticides from soil residues (not fresh spray) at a
1 to 1 rate, which will put a squash eating fanatic over the FDA limit per
person per year for the pesticide. Conclusive?


Mollison told a story about cadmium contamination in truck plots around
Canberra, and that would be another nasty; but in that case it was supposed
to be a side effect of fertidlizer applications, not pesticide. Like most of
Bill's stories, I don't know any details

And remember that orchards used to get copper and arsenate of lead applied.
That would be a counter-indication for some sorts of agricultural production
on that land.
