You aren't supposed to LICK the cameras, Andrew! :-)
Two things: first, if you're eating organically, you don't have much
in the way of heavy metals in your "nutritious discharges."
Second: proper composting chelates heavy metals. You need to have
adequate carbon during the composting, typically from sawdust, which
has lignin, which binds to the metals and renders them organically
neutral.
But don't believe me, read the website! It's actually quite
entertaining, and I so applaud the author's willingness to make it
free on the web that I bought a copy of the book. Makes better
washroom reading than a web page.
