Nanosilver is used in countless consumer products as an antimicrobial agent. It offers the potential benefit of killing dangerous bacteria, but its toxicity to fish and other organisms could impact the environment negatively.
As a result of participating in this program, visitors will be able to:
Recognize that nanosilver products are already available for purchase.
Understand that silver is toxic to bacteria.
Define nanosilver as particles of silver small enough to be measured in nanometers, or billionths of an inch.
Understand that small particles of a material will often react more rapidly than large particles because of their large surface area.
Understand that nanosilver presents both potential benefits for people and potential risks for the environment.
