SUBJECT: Sprague-Dawley rats (male, female) healthy and free of disease.

Procedure: Acute Inhalation Toxicity Test PRO/MT INHAL 29/8. The inhalation test was performed using two exposures. In each of the two runs, 5 animals were exposed in a 38 liter, all-glass chamber for a 1-hr period. Following one hour exposure period, the animals were then returned to their cages for observation at one hour, after hours and once daily thereafter, for a period of fourteen days.

OBSERVATIONS: All test animals appeared incapacitated during the 1 hour exposure.

GROSS PATHOLOGY: No abnormalities were noted at necropsy.

RESULT: CAP-STUNâ formulation was not toxic to the test animals when they were exposed to a concentration of 56.3 mg/1, which was the highest concentration available in the test system. The LC50 was thus calculated to be far greater than 56.3 mg/1. No attempt was made to obtain the LC50 values because the test system was already at its maximum operation capacity. Increasing that capacity would physically endanger the test animals and could create LC50 values that would not be related to the exposure of the chemical. It was also our estimate that the current exposure condition (concentration and duration) already surpassed that which would be expected in the normal usage of the device.
