A process that estimates the amount of a chemical that enters or comes into contact with people or animals. An exposure assessment also describes how often and for how long an exposure occurred, and t [..]

One of the key steps in risk assessment, this relates to a thorough evaluation of who, or what, has been exposed to a hazard and a quantification of the amounts involved.

The quantification of the amount of exposure to a hazard for an individual or group (WHO, 1979).

The determination or estimation (qualitative or quantitative) of the magnitude, frequency, duration, route, and extent (number of people) of exposure to a chemical.

Identifying the pathways by which toxicants may reach individuals, estimating how much of a chemical an individual is likely to be exposed to, and estimating the number likely to be exposed.

Identifying the pathways by which toxicants may reach individuals, estimating how much of a chemical an individual is likely to be exposed to, and estimating the number likely to be exposed.

Measurement or estimation of the magnitude, frequency, duration and route of exposure to a substance for the populations of interest.

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 assessment also descr [..]

  The process of finding the ways people come in contact with chemicals, how often and how long they come in contact with chemicals, and the amounts of chemicals with which they come in contact.

Identifying the pathways by which toxicants may reach individuals, estimating how much of a chemical an individual is likely to be exposed to, and estimating the number likely to be exposed.

Identifying the ways in which chemicals may reach individuals (e.g., by breathing); estimating how much of a chemical an individual is likely to be exposed to; and estimating the number of individuals [..]

The exposure assessment is the determination of the emissions in order to estimate the concentrations/doses of a substance to which human populations or environmental spheres (water, soil and air) are or may be exposed.

An investigation of the means by which organisms may encounter a potentially toxic level of a chemical or other environmental stressor.
