Atrazine questions

SludgeMunkey · Mar 24, 2009

I have been reading up on atrazine and its effects on amphibians a bit (obscene concentrations of it used locally here) and was curious if it is actually the atrazine causing adverse effects or if this was caused by the cyanuric acid formed by atrazine decomposition. I cannot seem to find any information about that detail other than thats what it breaks down into by biological action.

I dug up several links that may or may not help. I believe this first one is the paper that first documented low dose toxicity of atrazine on frogs. I haven't read the whole thing, but the authors say "atrazine", and it's a lab study, so I'm assuming it's atrazine itself, rather than breakdown products:

This other source lists studies of toxic effects of atrazine:

and of cyanuric acid:

http://www.pesticideinfo.org/Detail_Chemical.jsp?Rec_Id=PC33021#Ecotoxicity

It lists a number of studies with amphibians for atrazine, but not for cyanuric acid. So maybe effects of cynanuric acid have not been studied much yet.
