Which exposure route involves breathing in a pesticide without personal protective equipment (PPE)?

Inhalation is the exposure route that involves breathing in a pesticide. This can happen when an individual is in an area where the pesticide is being applied, particularly if there are no protective measures like personal protective equipment (PPE) in place. Inhalation of pesticides can lead to absorption of chemicals directly into the respiratory system, which can result in adverse health effects. Understanding this route is crucial for promoting safety practices among those who handle or are in proximity to pesticide applications, emphasizing the need for proper protective equipment to prevent inhalation exposure and ensure health and safety. The other exposure routes, such as oral, ocular, and dermal, involve entirely different mechanisms of contact with the pesticide, affecting different body systems.
