What are the four routes a pesticide can enter the body?

The four routes pesticides can enter the body are through the skin (dermal), through the eyes (ocular), by breathing in (inhalation), and by swallowing (ingestion). Skin contact can allow absorption; eye exposure can lead to local and systemic effects; inhaled particles or vapors can reach the lungs and bloodstream; swallowing brings the chemical into the gastrointestinal tract where it can be absorbed. This combination covers the common pathways for exposure, making swallowing (ingestion) the fourth route in the standard set. Other phrasings like oral or exposure-focused terms are close but less precise about the actual entry route.
