Exposure Pathway
What does it mean if an exposure pathway is incomplete?
If an exposure pathway is incomplete, then at least one part of the exposure pathway is missing and no one is exposed to the chemical by that route of exposure. For example, if a person who has a contaminated private well is using bottled water for drinking or cooking, then the ingestion, or swallowing, exposure pathway is incomplete and there is no exposure to contaminated water. Clean-up efforts take actions that remove one or more exposure pathway parts to make the exposure pathway incomplete.
