The term, acute, means a stimulus severe enough to rapidly induce an
	 effect. In aquatic toxicity tests, a deleterious response (e.g., mortality,
	 disorientation, immobilization) to a stimulus observed in 96 hours or less is
	 considered acute. When referring to aquatic toxicology or human health, an
	 acute effect is not always measured in terms of lethality.
The term, chronic, means a stimulus of the lowest concentration of a
	 constituent causing observable effects. In aquatic toxicity tests, observable
	 effects may include lethality, reduced growth, or reduced reproduction, usually
	 a four- to seven-day test.
