Materials and methods

Principles of method if other than guideline:
Concentrated vapor inhalation was performed exposing groups of 6 male or female albino rats to a flowing stream of vapor-loaded air. The vapor-air mixture was generated by passing 2.5 l/min of dried air at room temperature through a fritted glass disc immersed to a depth of at least one inch in approximately 50 ml of the test substance in a gas-washing bottle. Inhalations were continued for 8 hours in a logarithmic series. The observation period lasted 14 days.
GLP compliance:
no
Test type:
other: inhalation risk test
Limit test:
no
