Which of the following describes a recognized main route of exposure to pesticides?

• A. Inhalation is the only route of exposure.
• B. Dermal exposure is not a route of exposure.
• C. Ingestion is a recognized route of exposure to pesticides.
• D. Visual exposure is a route of exposure.

Answer: (C)

Exposure to pesticides can enter the body mainly through inhalation, dermal contact, or ingestion. Ingestion is a recognized route because residues can be swallowed, for example when contaminated hands touch the mouth, or after eating or drinking while handling pesticides. Saying inhalation is the only route ignores the other valid entry paths, and dermal exposure is indeed a real route, so denying it isn’t accurate. Visual exposure isn’t a standard route of entry for pesticides, even though splashes to the eyes can occur, they’re not described in the same way as inhalation, dermal, or ingestion. Therefore, ingestion correctly identifies a recognized route of exposure.
