Which of the following is NOT a way pesticides can enter the body?

Pesticides can enter the body through various routes, and it's important to understand how toxins might be absorbed to implement proper safety measures. The skin, eyes, and mouth are all pathways through which pesticides can enter the system.

Skin exposure is significant as pesticides can be absorbed through dermal contact. The eyes also provide a route for exposure, as contact with pesticides can lead to absorption through the mucous membranes. Ingestion is a common method of exposure, especially if pesticide residues are on hands or food items.

Considering the routes of exposure, the nasal passages do not typically absorb pesticides in the same way as the other options do. The nasal route may allow for airborne exposure to some substances, but it is not one of the primary pathways for pesticide entry into the body compared to direct contact with skin, ingestion through the mouth, or exposure through the eyes. Consequently, the correct answer reflects an understanding of how the body interacts with pesticides and which routes are more prevalent for absorption.
