Which of the following is NOT one of the main routes of bodily entry for pesticides?

The correct answer is the option that represents a route of entry that is not considered one of the primary ways pesticides enter the human body. Pesticides typically enter the body through three main routes: skin (dermal exposure), ingestion (consuming contaminated food or drink), and inhalation (breathing in aerosols or vapors). While the mouth is involved in ingestion, it is not categorized as a separate route of entry in the context of directly entering through bodily pathways.

The feet, while they can come into contact with pesticides on the ground, are not recognized as a specific or primary route of entry, as exposure through the feet primarily leads to dermal absorption. In contrast, the skin itself is a significant entry point. Thus, identifying the feet as a route of entry is not supported by the established understanding of pesticide exposure pathways.
