Hi Wendy

Quick look at Chemidplus Advanced shows it to be pretty nasty.  Most of the LDs are in microgram/kg.  There are many synonyms, but I did not see parathion (see below).  It's a EPA pcode waste, which means very toxic to the environment for sure.

Has anyone ever worked with paraoxone?  One of our folks was asking me questions about it, and I had a little information from some of my reference materials, but no practical knowledge.  One of the big questions was in regards to toxicity - the group found conflicting MSDSs which stated alternatively that it's not a hazard at all versus it's a horribly toxic hazard.  Then someone else added to the confusion by telling them it's "1,000 times more toxic than parathion," which I couldn't find any data to support.  I'd like to be able to tell them what the real risks and hazards would be if they decided to go ahead with their project.
