Which of the following is considered a major route of pesticide exposure?

• A. Oral, Inhalation, Dermal
• B. Oral, Dermal, Injection
• C. Inhalation, Dermal, Ocular
• D. All of the above

Answer: (A)

Pesticide exposure enters the body most often through three pathways: the mouth, the skin, and the lungs. These are the major routes because they are the most likely and can lead to systemic exposure during typical work activities. Ingestion happens when hands or contaminated objects touch the mouth and food or drink, dermal exposure occurs from skin contact with spray residues or contaminated clothing, and inhalation comes from breathing in aerosols, vapors, or dust during mixing, loading, or spraying. Eye exposure and rare injection incidents can occur, but they are not considered the primary routes for most exposure scenarios. So, the combination of oral, dermal, and inhalation accurately reflects the major routes.
