What is an example of a chemical agent used in disinfection?

Hydrogen peroxide is a well-known chemical agent that is widely used in disinfection due to its ability to kill a broad range of microorganisms, including bacteria, viruses, and fungi. Its effectiveness stems from its oxidative properties, which disrupt the cellular structure of pathogens. Additionally, hydrogen peroxide is valued for its relatively low toxicity to humans and the environment when compared to some other disinfectants, making it a popular choice in healthcare settings.

While steam and heat are effective for sterilization rather than disinfection, they do not qualify as chemical agents. Steam is a physical method that utilizes moisture and high temperature to achieve sterilization, while heat can be applied through various means but is similarly not a chemical agent. Ultraviolet light, while effective for disinfection, operates via physical means by causing damage to the DNA or RNA of microorganisms and is not a chemical agent.
