The remaining chemicals are mainly copper sulfate and fungicides, neither
of which are cause for alarm (unless you get down on your hands and knees
and gnaw on the wood... :-o).

Perhaps you should provide more information on the fungicides you're
referring to, and which of them might or might not be safe near edible
plants. The OP may or may not want to stick some chives or parsley or other
stuff in the ground near the treated wood.


Besides, there are worse sources of pollution in your neighbourhood, such
as the car in your driveway or the power mower you use.

Unless you're the kind of slug who lets his car ooze fluids for years on end
without fixing it, you cannot compare engines to fungicides/pesticides in
contact with the soil.
