Which term best describes the entry of pesticides through the skin?

The term that best describes the entry of pesticides through the skin is absorption. This process involves the penetration of chemicals through the skin barrier into the body. Absorption is a critical consideration when handling pesticides, as it can determine the level of exposure a person may experience.

When pesticides come into contact with the skin, they can be absorbed into the bloodstream, leading to potential health risks. Understanding absorption is essential for safe handling practices, including the use of personal protective equipment (PPE) to minimize contact with the skin.

In the context of pesticide exposure, inhalation refers to breathing in pesticides, while oral ingestion involves swallowing substances. Direct contact generally implies that pesticides are applied to the skin, but it does not necessarily indicate that they are being absorbed into the body. Thus, absorption is the most accurate term for this specific method of pesticide entry.
