According to research, workers mixing pesticides get ___ percent of their exposure through their hands.

• A. 100 percent
• B. 50 percent
• C. 25 percent
• D. 85 percent

Answer: (D)

Hands are the main exposure route during mixing because this task involves direct and frequent contact with the concentrated product, splashes, and contaminated surfaces. Research shows that a large portion of total pesticide exposure comes through the skin on the hands—about 85 percent. That’s why wearing proper hand protection and using correct mixing procedures are so crucial for reducing exposure. While inhalation and other routes can occur, they contribute less to exposure in the mixing task, which is why the share from hands isn’t 100 percent or a much smaller fraction like 25 or 50. Taking steps like using appropriate gloves, avoiding contact with the face, and washing hands thoroughly after mixing helps cut this dominant exposure path.
