It's amazing that you'd even think that the compunds are the same. They
simply aren't. Not even close.

You are correct... the compounds in the sound are much more toxic since
there is no regulation as to what is put through the system [ie: medical
waste, dangerous chemicals, etc].... and there is no available reaction to
quickly breakdown the solids like in a septic tank due to the sedimentation
preventing oxygen from reaching the lower strata of sedimentation.
