Is it true or false that pesticide residues are absorbed through the skin at the same rate on different body parts?

1. True

2. False

3. Depends on the pesticide

4. Varies with weather conditions

The correct answer is: False

The statement is false because the rate at which pesticide residues are absorbed through the skin varies significantly between different parts of the body. Factors such as skin thickness, the presence of hair follicles, the degree of moisture in the skin, and the vascularity of the underlying tissues all influence absorption rates. For instance, areas of the skin that are thinner, more vascular, or have more openings (like various folds or the face) can absorb pesticides more readily than thicker areas, such as the palms of the hands or the soles of the feet. Understanding this variability is crucial for minimizing exposure risks during pesticide handling and application.
