Which of the following is NOT a route through which pesticides can enter the body?

Pesticides can enter the body through several routes, and understanding these is crucial for safety and application practices. The primary routes of entry include:

• Inhalation: This route occurs when pesticides are breathed in through the nose or mouth, allowing them to enter the lungs and subsequently the bloodstream. It is a significant concern during the application of pesticides, especially in poorly ventilated areas.

• Dermal: Pesticides can penetrate through the skin when handling chemicals or being in contact with treated surfaces, allowing them to enter the body. This is a common route of exposure for applicators, and protective gear can help minimize risk.

• Ocular: Pesticides can also enter through the eyes. Exposure can happen when applying pesticides or when handling containers without proper eye protection. This route may lead to immediate irritation or more severe effects depending on the chemical involved.

In contrast, exhalation is the process of breathing out. It does not serve as a route for pesticides to enter the body; rather, it allows substances to leave the body. Therefore, identifying exhalation as a route of entry is incorrect, making it the appropriate answer for the question.
