-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA224 According to the MSDS, The LD50 for rats is 5800 mg/kg (i.e., it takes a lot to kill 50% of the rats) and it is not a hazard to fish (the LC50 is also high). It breaks down relatively rapidly in the environment. Just for reference, LD50 of water for rats is >90 ml/kg (http://conspiracyfactory.blogspot.com/2007/05/everything-is-toxic.html)
