What are the four ways pesticides can enter the body?

Pesticides can enter the body through four primary routes: the skin, lungs, mouth, and eyes.

When pesticides come into contact with the skin, they can be absorbed through the dermal layer, leading to systemic effects. Respiratory exposure occurs when pesticides are inhaled, allowing them to enter the bloodstream directly through the lungs. Ingestion through the mouth represents another significant route, as swallowing pesticides can lead to toxic effects throughout the body. Additionally, exposure through the eyes is also critical, as the mucous membranes can absorb chemicals very efficiently. Each of these routes emphasizes the importance of protective measures when handling pesticides to minimize exposure and health risks.
