Right, you wouldn't be able to do this with street trees for that reason, but park trees are fine. The soil just needs to be tested on a regular basis for heavy metals, but that isn't especially difficult; e.g. this has already been done for a lot of community gardens in NYC. While fruit definitely contains whatever pollution is in the environment, unlike many mushrooms it generally doesn't hyper concentrate it.
