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.   

Thanks,
Wendy
