It's not very poisonous, although it sounds like it is.  I once got a 
splash of it in my mouth, and so I went to the doctor. He said that I'd 
have to have swallowed about 1 table spoon in order for there to have 
been a problem. Regarding the environmental impact, I'm not a scientist 
but I doubt very much that using a small amount of ferricyanide has more 
environmental impact than my driving to work (once).  Finally, as to the 
longevity of prints, they do need to be fixed afterwards, but then 
what's the problem?  It's also used in bleach/redevelopment toners (as 
I'm sure you know), many of which make the print more archival. One 
should be careful with it, like you should be will all photo chemicals. 
You're over-reacting a bit. (And no, I don't usually bleach prints.)
