Since there are some who are hypersensitive, some who
are almost immune,
and the curve is NOT a smooth bell curve, toxicity is generally measured
in "LD50". That is the dosage at which HALF of the subjects die. (Note
that because of the skews of the curve, that is the MEDIAN, NOT THE MEAN)
MOST LD50 numbers are expressed as the LD50 for rats, since killing half
of your human subjects, EVEN if they're grad students!, is frowned upon.
However, the IRB did let me kill several undergraduates once. Also, it is
acceptable to maim medical students, as long as they are permitted to
graduate.
