This exposure is similar to the absorption exposure with one key difference; this exposure will cause damage to the skin as it makes its way into your body.

• A. Absorption
• B. Contact
• C. Ingestion
• D. Injection

Answer: (B)

The key idea is understanding dermal exposure routes and how skin interaction can cause damage during entry into the body. This scenario describes a route that is like absorption through the skin, in that the substance is moving toward entry into the body, but with the added detail that it causes damage to the skin as it makes its way in. That local skin damage is a hallmark of dermal contact exposure—where the chemical is in contact with the skin and can injure the skin itself while some of it may subsequently be absorbed. The other routes involve ingestion, injection, or a pure, non-local absorption, which don’t fit the described pattern of skin damage occurring as the substance enters the body.
