What are the three routes of pesticide entry into the body?

The three routes of pesticide entry into the body are dermal, oral, and lungs. This means pesticides can enter through the skin (dermal), through the digestive system (oral), and by being inhaled into the respiratory system (lungs).

Understanding these routes is crucial for safety practices in handling pesticides, as it helps individuals identify potential exposure risks. For example, dermal exposure can occur during mixing or applying pesticides, oral exposure can happen accidentally if hands or contaminated surfaces are not washed before eating, and inhalation can occur if pesticides are sprayed in a manner that creates airborne particles. This awareness is essential for implementing protective measures to minimize the risk of pesticide-related harm.

The other options incorporate terms that may relate to pesticide exposure but don't accurately define the primary routes of entry into the body. The term "topical" suggests surface application without specifying that it includes dermal exposure, while "environmental" might refer to external factors influencing exposure rather than direct entry routes. "Injection" does not typically classify as a route of entry for pesticides in practical scenarios since pesticides are generally not injected.
