What is the most common route of pesticide exposure?

• A. Dermal exposure
• B. Inhalation exposure
• C. Ingestion exposure
• D. Eye exposure

Answer: (A)

Dermal exposure is the most common route because pesticides are typically handled or come into contact with skin during mixing, loading, applying, or handling treated materials. The skin is the body's largest surface area and many pesticides readily pass through it, so even small amounts that touch and later absorb into the skin can create significant exposure. Inhalation and ingestion can occur, but they are usually less frequent pathways in routine pesticide handling. Eye exposure happens, but it’s less common and often occurs from splashes or drift rather than ongoing contact. To reduce dermal exposure, wearing appropriate PPE such as gloves, long sleeves, and protective clothing, along with proper hygiene and changing contaminated clothing, is essential.
