What are the primary routes of human exposure to pesticides?

1. Oral, dermal, eye, and inhalation

2. Oral, nasal, dermal, and ocular

3. Ingestion, injection, inhalation, and contact

4. Eye, ear, mouth, and skin

The correct answer is: Oral, dermal, eye, and inhalation

The primary routes of human exposure to pesticides include oral, dermal, eye, and inhalation. Each of these routes is significant in understanding how pesticides can enter the body and pose health risks. Oral exposure occurs when pesticides are ingested, which can happen accidentally through contaminated food, hands, or surfaces. Dermal exposure refers to the absorption of pesticides through the skin, which is particularly relevant for agricultural workers who may handle chemical products directly. Eye exposure can occur through splashes or airborne particles, leading to potential irritation or damage. Inhalation involves the respiratory uptake of pesticide vapors or dust, which is critical in situations where pesticides are applied as aerosols or in enclosed spaces. Recognizing these routes is crucial for implementing proper safety measures and ensuring that individuals who handle or are in proximity to pesticides take appropriate precautions to minimize potential health effects.
