Exposure pathways definition

Exposure pathways means the methods by which humans can come into contact with contamination including, but not limited to, the ingestion-dermal exposure pathway and the inhalation exposure pathway.
Exposure pathways means air, soil, water, or food;
Exposure pathways are means by which hazardous materials move through the environment from a source to a point of contact with people, or with animal or plant populations. A complete exposure pathway must have four parts: (1) a source of contamination, (2) a mechanism for transport of a material from the source to the air, surface water, groundwater, or soil, (3) a point where people come in contact with contaminated air, surface water, groundwater, or soil, and (4) a route of entry into the body. Routes of entry can be eating or drinking contaminated materials, breathing contaminated air, or absorbing contaminants through the skin. Risks can be assessed when an exposure pathway is complete. If any part of an exposure pathway is absent, the pathway is said to be incomplete and no exposure or risk is possible. In some cases, although a pathway is complete, the likelihood that significant exposure will occur is very small.
