What is exposure in the context of pesticides?

• A. Contact with pesticide
• B. Ingestion of food containing pesticide residue
• C. Exposure to sunlight while applying pesticides
• D. Exposure to noise during application

Answer: (A)

Exposure is about coming into contact with the pesticide so it can enter the body. In practical terms, this means skin or eye contact with the chemical, or breathing in spray droplets during handling, mixing, loading, or application. This direct contact is the primary way a pesticide can be absorbed and cause harm, so safety efforts focus on preventing any contact—using gloves, masks, protective clothing, and proper containment.

The other ideas describe different situations that aren’t the core way exposure is defined in this context. Ingestion of contaminated food is a route of exposure, but the everyday safety focus when discussing exposure during application is on direct contact with the chemical itself. Exposure to sunlight or to noise during application isn’t chemical exposure, but rather environmental or physical hazards.
