Chronic toxicity is caused by repeated exposure to a harmful substance for part of the life-span of an animal, for a major portion of its life-span, or for all of its life-span. Repeat dose toxicity studies are usually conducted in animals with the main aim of defining a No Observed Adverse Effect Level (NOAEL).
