EPA EcoBox Tools by Exposure Pathways
An exposure pathway is the pathway by which a stressorAny physical, chemical, or biological entity that can induce an adverse response (synonymous with agent). travels from a source to receptor(s) (U.S. EPA OSWER, 1997). A complete picture of how, when, and where exposure occurs or has occurred is developed by evaluating sources and releases of a stressor, distribution of a stressor in the environment, and extent and pattern of contact with a stressor (U.S. EPA, 1998). In evaluating potential exposure pathways for ecological receptors, air, soil, water, sediments, and food chain exposures are considered.
