What is the term for contact between a chemical and the skin?

The term for contact between a chemical and the skin is dermal exposure. This concept is crucial in understanding safety protocols in handling hazardous substances, as it encompasses scenarios where skin comes into direct contact with chemicals, which can lead to skin irritation, absorption of harmful substances into the bloodstream, or other adverse health effects. Recognizing this term emphasizes the importance of using personal protective equipment (PPE) and following proper handling procedures to minimize the risk of such exposure.

Other terms provided do not effectively describe this form of contact. Dermatitis refers to a skin condition that results from or is aggravated by exposure to irritants or allergens, while a defoliant is a substance used to strip leaves from plants, and email is unrelated to the topic of chemical exposure. These distinctions highlight the specific nature of dermal exposure in the context of chemical safety.
