How can a pesticide enter the body?

Pesticides can enter the body through multiple pathways, and the most comprehensive option is that they can be absorbed through the skin, eyes, mouth, and inhalation. Each of these routes represents a significant method of exposure.

The skin is a common entry point because it can absorb certain chemicals present in pesticides, especially if the pesticide formulation allows for dermal penetration. Eyes and mucous membranes are also sensitive areas that can facilitate absorption of chemicals.

Inhalation can occur when pesticides are present in the air as vaporized droplets, aerosols, or dust, allowing them to enter the respiratory system quickly, bypassing the body's first line of defense.

While ingestion and skin contact might be thought of as key pathways, they are not exclusive. The other choices limit the ways pesticides can enter the body and do not reflect the full range of exposure methods, making them less accurate.
