I posted the table some time ago.
Here it is again. Credits are on the top, the reference is at the bottom

Relative toxicity of Plutonium
Some time ago there was a question about the relative toxicity of Pu.
In 1976, Dave Myers and I wrote a paper titled,
"Selected Aspects of Plutonium in the Environment, and Its Toxicity."
Table 17, from this paper, gives the following:

Agent   Action & Site  Approximate amount to cause
       death in hours to days.
Pu (ingest)   GI tract   500 mg
Pu (inhal)   Pul. edema   25 mg
HCN    Blood anoxia   50 mg
Parathion   Blocked synapses  100 mg
Arsenic   Chemical poison  120 mg
Botulism toxin  Resp. paralysis  5 E-5 mg

Our reference for the common poisons was:
