I've come across a few interesting web sites with info on pollution in the
city and it's effects on growing one's own produce.

The first is an extreme example of pollution, but interesting all the same.
The New Orleans Residents' Guide To Do It Yourself Soil Clean Up - this
advice for people cleaning up after Hurricane Katrina.

The other is a query from someone wanting to understand whether there are
dangers in using city rainwater to water their vegetables.

Interesting conversations on printing inks when using paper to reduce smell
in worm farms. Don't know what inks are used in Australia, but it's good to
be aware of it...
