Which of the following is NOT considered a route of entry for pesticides?

When evaluating routes of entry for pesticides, dermal, inhalation, and oral routes are recognized as the primary ways through which pesticides can enter the human body. Dermal refers to absorption through the skin, inhalation denotes breathing in pesticide particles or vapors, and oral signifies ingestion.

Topical, however, is typically associated with the application of substances directly to the skin for effects on localized areas and is not classified as a route where pesticides would generally enter the systemic circulation in a hazardous context. While topical application may lead to limited dermal absorption, it doesn't represent an entry point for pesticides in the same manner that dermal, inhalation, and oral routes do. Therefore, identifying topical as not being a route of entry aligns with the established understanding of how pesticides interact with the body.
