Which body part is least likely to absorb pesticides among the following?

The feet are the body part least likely to absorb pesticides compared to the other options listed. This can be attributed to a couple of factors. Firstly, the skin on the feet is generally thicker and less permeable than the skin on the hands, forearms, and especially the eyes. A thicker stratum corneum, the outermost layer of skin, provides a more effective barrier against chemical absorption.

Additionally, the feet are often covered by socks and shoes when working in environments where pesticides may be present, which further reduces direct contact and absorption. In contrast, hands and forearms are more frequently exposed to pesticide application, increasing the risk of absorption through thinner skin. The eyes are also particularly vulnerable to chemical exposure, as the mucous membranes can absorb substances rapidly.

In summary, the reduced exposure due to clothing and the nature of the skin make the feet the least likely body part to absorb pesticides.
