Exposure assessment - A process that estimates the amount of a chemical that enters or comes into contact with people or animals.
Exposure: See Injection.
Extractable: A compound that can be partitioned into an organic solvent from the sample matrix and is amenable to gas chromatography. Extractables include semivolatile (BNA) and pesticide/Arochlor compounds.
Exposure Route- The way a chemical or pollutant enters an organism after contact; i.e. by ingestion, inhalation, or dermal absorption.
Exposure-Response Relationship- The relationship between exposure level and the incidence of adverse effects.
Exposure of a non-human organism to a stressor.
Ecological Impact
The effect that a man-caused or natural activity has on living organisms and their non-living (abiotic) environment.
In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g., skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose.
Lead exposure was present in diverse forms such as food, drinking water, air, soil dust and consumer products.
