Completed exposure pathway:

A pathway of exposure is considered completed when all five elements are present. A completed pathway connects the source of the material to people.

  1. Source
  2. Media
  3. Exposure point
  4. Exposure route
  5. People

Source: EPA

Will exposure from a completed pathway affect my health?

Whether or not a person experiences health effects from exposure to materials in the environment depends on a combination of several site-specific factors including.

  • Kind of material released
  • Amount of material available at the exposure point
  • Physical and chemical form of the material
  • Environmental conditions
  • Length of exposure time
