Exposure pathway means the path a hazardous substance takes or could take from a source to an exposed organism. An exposure pathway describes the mechanism by which an individual or population is exposed or has the potential to be exposed to hazardous substances at or originating from a site. Each exposure pathway includes an actual or potential source or release from a source, an exposure point, and an exposure route. If the exposure point differs from the source of the hazardous substance, the exposure pathway also includes a transport/exposure medium.
Exposure pathway means the course a contaminant of concern may take from its source area to an exposed organism. Each exposure pathway includes a source or release from a source, a point of exposure, and an exposure route.
Exposure pathway means the course a chemical or physical agent takes from a source to an exposed organism.
Examples of Exposure pathway in a sentence
A No Observed Adverse Effects Level refers to a dose of chemical that is ingested, while a No Observed Adverse Effects Concentration refers to direct exposure to a chemical such as through the skin.(qq) "Point of Departure" means the target risk level that risk to an individual is considered insignificant.(rr) "Potentially Complete Exposure Pathway" means a pathway that, due to current site conditions is incomplete, but could become complete at a future time because of changing site practices.
More Definitions of Exposure pathway
Exposure pathway means a course taken by a contaminant by way of a transport medium after its release to the environment.
Exposure pathway means the route a contaminant takes from its source (where it began) to its end point, and how people can come into contact or otherwise are exposed to the contaminant. An exposure pathway has five parts: a source of contamination (such as a leaking tank), an environmental medium and transport mechanism (such as movement through groundwater), a point of exposure (such as a private well), a route of exposure (eating, drinking, breathing, or touching), and a receptor population (people potentially or actually exposed). An exposure pathway is termed a completed exposure pathway only when all five parts are present.6
Exposure pathway means the manner by which a person or an organism may be exposed to a chemical of concern or contaminant. A complete exposure pathway consists of a source, a release from a source, a migration and transport mechanism, an exposure medium (e.g., air) or media (in cases of intermediate transfer), an exposure point, and an exposure route.
Exposure pathway means the physical course a chemical or pollutant takes from its source to the organism exposed.
Exposure pathway means the course a chemical(s) of concern takes from a source area(s) to a receptor. Each exposure pathway includes a source area(s), a point of exposure, and an exposure route, and usually a transport/exposure medium or media.
Exposure pathway means the course that a chemical of concern takes or may take from a source area to a receptor. Each exposure pathway includes a source or release from a source of a chemical of concern, a point of exposure, an exposure route, and the receptor.
Exposure pathway means the pathway through an environmental medium by which a contaminant is conveyed to a receptor.
