Contributors in Toxicology

Toxicology

systemic absorption

Biology; Toxicology

Uptake to the blood and transport via the blood of a substance to an organ or compartment in the body distant from the site of absorption.

antimetabolite

Biology; Toxicology

Substance, structurally similar to a metabolite, which competes with it or replaces it, and so prevents or reduces its normal utilization.

biomarker of effect

Biology; Toxicology

Biomarker that, depending upon the magnitude, can be recognized as associated with an established or possible health impairment or disease.

effect biomarker

Biology; Toxicology

Biomarker that, depending upon the magnitude, can be recognized as associated with an established or possible health impairment or disease.

abiotic degradation

Biology; Toxicology

Process in which a substance is converted to simpler products by physical or chemical mechanisms: examples include hydrolysis and photolysis.

absorptance in chemistry (α)

Biology; Toxicology

Ratio of the absorbed to the incident radiant power. Also called absorption factor. When α ≤ 1, α ≈ Ae, where Ae is the Napierian absorbance.

chronic effect

Biology; Toxicology

Consequence which develops slowly and (or) has a long-lasting course: may be applied to an effect which develops rapidly and is long lasting.
