Subject: Information on GF Toxicity (U)

(U)  In general, the inhalation toxicity of GF is comparable to 
that of GB and GD, except for monkeys, which are almost twice as 
susceptible to GB and GD as GF.  The bare skin percutaneous 
toxicity of GF liquid appears to be somewhat greater than GO and 
several times grater than GB.

(U)  Some toxicity data:

     Mouse (subcutaneous)         LD50=400 micrograms/kilogram
     Rabbit (intravenous)         LD50=100 micrograms/kilogram

     Additional data:

     Estimated inhalation toxicity:  LCt 50, 350 to 450 
	milligram-minute/cubic meter

     Percutaneous toxicity:  LD50=0.5 milligram/kilogram
