Routes of Exposure - Ingestion describes exposure through which route?

• A. Inhalation
• B. Ingestion
• C. Absorption
• D. Dermal

Answer: (B)

Exposure routes describe how a contaminant enters the body. Ingestion means exposure through swallowing a contaminant, such as from contaminated food or water or from hand-to-mouth transfer of dust or substances. After swallowing, the substance passes into the digestive system where it can be absorbed into the bloodstream. This is different from inhalation (entry through the lungs from breathing contaminated air) and dermal (entry through the skin). Absorption is the process of uptake, which can occur via skin or mucous membranes, but the route itself is specifically mouth-to-swallowing for ingestion.
