Which area is a thinner area of skin more prone to dermal pesticide exposure?

• A. Forehead
• B. Back of the hand
• C. Sole of the foot
• D. Inner thigh

Answer: (A)

Dermal absorption of pesticides increases where the skin is thinner and more permeable. The forehead has some of the thinnest skin on the body, with a thin epidermis and good permeability, so pesticides that contact this area can penetrate more quickly into the body. In contrast, the soles of the feet have thick skin with a strong outer barrier, and the inner thigh and back of the hand have thicker or less permeable skin compared to the forehead. Because of this thin, highly permeable skin on the forehead, it’s the area most prone to dermal pesticide exposure.
