Exposure assessment

Exposure assessment
The process of finding out how people come into contact with a hazardous substance, how often and for how long they are in contact with the substance, and how much of the substance they are in contact with.

Exposure Assessment: Measurement or estimation of the magnitude, frequency, duration, and route of exposure of humans, animals, materials, or ecological components to substances in the environment.

The process of estimating or measuring the intensity, frequency, and duration of exposure to an agent.

Exposure assessment - A process that estimates the amount of a chemical that enters or comes into contact with people or animals.

In exposure assessment, the amount of a substance given to a test subject (human or animal) to determine dose-response relationships. Since exposure to chemicals is usually inadvertent, this quantity is often called potential dose.

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.

Integrated Exposure Assessment: Cumulative summation (over time) of the magnitude of exposure to a toxic chemical in all media.
Integrated Pest Management (IPM): A mixture of chemical and other, non-pesticide, methods to control pests.

integrated exposure assessment A summation over time, in all media, of the magnitude of exposure to a toxic chemical.

Applied Dose- In exposure assessment, the amount of a substance in contact with the primary absorption boundaries of an organism (e.g. skin, lung tissue, gastrointestinal track) and available for absorption.
Aqueous- Something made up of water.

Dose Rate: In exposure assessment, dose per time unit (e.g. mg/day), sometimes also called dosage.

The four steps of a risk assessment are: hazard identification (Can this substance damage health?); dose-response assessment (What dose causes what effect?); exposure assessment (How and how much do people contact it?); ...

Risk Assessment: A qualitative or quantitative evaluation of the environmental and/or health risk resulting from exposure to a chemical or physical agent (pollutant); combines exposure assessment results with toxicity assessment results to ...
