What are the main routes through which pesticides can enter the body?

The main routes through which pesticides can enter the body are indeed through the eyes, skin, mouth, and lungs.

When discussing the eyes, they can readily absorb chemicals; thus, exposure can occur if pesticides splatter or drift into the eyes. The skin is another significant entry point for pesticides, as these substances can penetrate the skin's barrier and enter the bloodstream, especially when personal protective equipment is insufficient or not used.

Inhaling pesticides is a critical route of exposure as well. When pesticides are aerosolized or become airborne during application, they can be inhaled directly into the respiratory system, leading to systemic absorption.

The mouth is included as it can be a route of exposure through inadvertent ingestion, such as when hands that have come into contact with pesticides are not washed before eating or touching the face.

This understanding of how pesticides can enter the body is crucial for implementing safety measures and minimizing risk during handling and application.
