I have heard the warning about heavy metals. Where do they come from?

Thank you,

I don't think it will hurt your bamboo but I would not eat the shoots
because of the heavy metals human waste contains.

Hello all,
I was wondering if anyone here had any experience with humanure and
bamboo growing. I have read "the Humanure Handbook" and am going to
start
processing my waste. I was wondering if there was any good research on
the
use of humanure and bamboo growth or if anyone had any useful info.

Thanks,
Gello
