Which term describes the length of time a pesticide is in contact with the skin, the rate of absorption through the skin, and how much skin is exposed?

• A. Exposure
• B. Acute Exposure
• C. Chronic Exposure
• D. Toxicity

Answer: (A)

Exposure is the term that best fits this description. It refers to the contact between a pesticide and the body, including how long the skin is in contact with the chemical, how quickly it can be absorbed through the skin (the absorption rate), and how much skin is actually exposed. These factors together determine how much pesticide can enter the body and how fast it can happen, which is the essence of dermal risk. Distinguish this from acute exposure, which focuses on a short-term event, and chronic exposure, which deals with long-term or repeated contact over time. Toxicity, on the other hand, is about the inherent harm a chemical can cause, not the specifics of the contact itself.
