Nano, Silver, and You
NECN broadcast this SciTech Today segment on January 28, 2009, and it explains some of the potential risks and benefits of silver nanoparticles in consumer products. Nano-sized particles of silver are terrific at fighting bacteria and mold, and are being used in hospital settings and for food storage. But they’re also being incorporated into more casual types of consumer products, like children’s toys and clothing. Some scientists believe silver nanoparticles in a rapidly increasing array of consumer products could impair the effectiveness of wastewater treatment plants, and accumulate in rivers and streams, harming wildlife.
