Which routes can a pesticide enter the body?

Pesticides can enter the body through several specific routes, and the accurate identification of these routes is essential for understanding safety and risk management in pesticide application.

The correct answer identifies three primary ways in which pesticides can enter the body: dermal (through the skin), inhalation (through the respiratory system), and oral (through ingestion). Dermal absorption can occur when pesticides come into contact with the skin, particularly if the skin is broken or if the pesticide formulation allows for absorption. Inhalation refers to the uptake of pesticide particles or vapors into the lungs, which can happen during spraying or application, especially if adequate ventilation or protective equipment isn’t used. Oral entry occurs when pesticides are accidentally swallowed, which can happen if hands contaminated with pesticides are not washed before eating or drinking.

By recognizing these routes, applicators can implement necessary precautions and protective measures to minimize exposure, such as wearing appropriate personal protective equipment (PPE) and adhering to safe handling procedures.

The other choices contain methods that are not standard routes for pesticide entry. For instance, terms such as "injection" and "entry" do not specifically refer to how most pesticides typically enter the body in an occupational context. Understanding these entry routes helps in developing strategies to reduce risks associated
