Texas Pesticide Applicator Practice Exam

Which areas of the body absorb pesticides quickly?

1. Eyes, ears, scalp, and genitals

2. Arms, legs, and abdomen

3. Chest, back, and fingertips

4. Feet, knees, and elbows

The correct answer is: Eyes, ears, scalp, and genitals

The areas of the body that absorb pesticides quickly include the eyes, ears, scalp, and genitals. This is due to several anatomical and physiological characteristics of these regions. The eyes and ears are composed of mucous membranes which allow for rapid absorption of substances directly into the bloodstream. The scalp has a high blood supply and thinner skin, facilitating the penetration of chemicals. Similarly, the genitals also have thin skin and are rich in blood vessels, further enhancing the absorption of substances applied to these areas. In contrast, the other body regions listed, such as the arms, legs, abdomen, chest, back, and fingertips, generally have thicker skin layers, which can act as a barrier to absorption. While they can absorb pesticides, the rate at which this occurs is typically slower compared to the specified areas. Additionally, the feet, knees, and elbows also have thicker skin which can further limit rapid absorption. Therefore, the characteristics of the skin and tissue in the areas mentioned in the correct choice significantly contribute to their ability to quickly absorb pesticides.
