Which of the following is a common route through which pesticides enter the body?

Pesticides can enter the body through multiple routes, making it crucial to understand all potential pathways for exposure. Skin absorption occurs when pesticides come into contact with the skin and penetrate the dermis, which can happen through direct handling of chemicals without proper protective equipment. Ingestion is another significant route; this can occur when pesticides enter the mouth, either accidentally or through contaminated food and drink. Inhalation happens when pesticide aerosols or vapors are breathed in, which is especially relevant in agricultural settings or during application processes where the pesticide is airborne.

Given that all these routes—skin absorption, ingestion, and inhalation—are valid channels for pesticide exposure, selecting the option that encompasses all of them recognizes the comprehensive nature of how pesticides can affect health. Understanding these routes emphasizes the importance of safety measures, such as wearing protective clothing, ensuring a safe application environment, and implementing proper hygiene practices to minimize exposure.
