(430 ILCS 35/2-6) (from Ch. 111 1/2, par. 252-6)
Sec. 2-6.
"Highly Toxic" means any substance which produces death within 14
days in at least half of a group of 10 or more laboratory white rats each
weighing between 200 and 300 grams, when a single dose of 50 milligrams or
less per kilogram of body weight, is orally administered or when inhaled
continuously for a period of one hour or less at an atmospheric
concentration of 200 parts per million by volume or less of gas or vapor or
two milligrams per liter by volume or less of mist or dust, provided such
concentration is likely to be encountered by man when the substance is used
in any reasonably foreseeable manner, or which produces death within 14 days
in at least half of a group of 10 or more rabbits tested in a dosage of 200
milligrams or less per kilogram of body weight, when administered by
continuous contact with the bare skin for 24 hours or less.
If the Director finds that available data on human experience with any
substance indicate results different from those obtained on animals in the
above named dosages or concentrations, the human data shall take
precedence.
