What are the primary routes by which pesticides can enter the human body?

Pesticides can enter the human body primarily through the dermal, ocular (eye), oral, and inhalation routes. The dermal route involves absorption through the skin, which is a significant pathway given that many pesticides can penetrate the skin. The ocular route refers to exposure through the eyes, which can occur if pesticides are splashed or drift into the eyes, potentially leading to irritation or more severe effects.

Oral exposure can happen if pesticides are ingested, either accidentally or through contaminated food or drink. Inhalation occurs when pesticide particles are breathed in, which can be a risk during application, especially in enclosed spaces. Understanding these routes is crucial for implementing safety measures and handling pesticides properly, as each route can lead to different health effects and require specific preventative strategies. This knowledge is essential for commercial applicators to protect themselves and others from potential pesticide exposure.
