What does the term "dermal contact" refer to in toxicology?

• A. The inhalation of toxic fumes
• B. The ingestion of harmful substances
• C. The absorption of chemicals through the skin
• D. The results of skin irritation from chemicals

Answer: (C)

The term "dermal contact" in toxicology specifically refers to the absorption of chemicals through the skin. This process is significant because the skin can serve as a route for various substances to enter the bloodstream, leading to systemic effects or localized skin reactions. Understanding dermal contact is crucial in toxicology as it highlights the importance of safety practices in handling chemicals, where skin exposure can lead to adverse health effects. In contrast, inhalation of fumes, ingestion of substances, and skin irritation may involve different exposure routes and mechanisms that are not directly included in the definition of dermal contact itself.
