hazard quotient (HQ)
Ratio of toxicant exposure (estimated or measured) to a reference value regarded as corresponding to a threshold of toxicity.
Note: If the hazard quotient exceeds unity, the toxicant may produce an adverse effect but normally this will require a hazard quotient of several times unity; a hazard quotient of less than one indicates that no adverse effects are likely over a lifetime of exposure.
