In which method do pesticides primarily enter the body through the skin?

• A. Oral
• B. Dermal
• C. Inhalation
• D. Absorption

Answer: (B)

The method in which pesticides primarily enter the body through the skin is dermal exposure. Dermal absorption refers specifically to the process by which substances, such as pesticides, penetrate the skin and enter the bloodstream. The skin acts as a barrier, but it is also permeable to certain chemicals, particularly if they are in liquid form or have low molecular weight. In scenarios where pesticides are applied as sprays, dusts, or liquids, dermal exposure can be significant if proper protective gear is not used. This is particularly relevant in jobs involving pesticide application, where workers may come into direct contact with these chemicals. Understanding dermal exposure is crucial for implementing safety protocols and ensuring the proper use of personal protective equipment (PPE) to minimize health risks. While absorption is a broader term that encompasses how substances pass through any biological barrier, including skin, the term "dermal" specifically denotes the route through the skin. Thus, focusing on dermal is more accurate in this context.
