The EPA recently issued a ruling that a Samsung washing machine must be regulated as a pesticide. That's because the washing machine, the "Silvercare" model, claims to kill germs by injecting 100 quadrillion silver ions into each wash load. The wastewater would be released into public water systems, and there have been questions about the safety of widespread nanosilver use. On today's Underreported, we'll look into potential misuses of nanotechnology.

Leonard speaks with Dr. Jennifer Sass, Senior Scientist in the Natural Resource Defense Council’s Health and Environment Program. Also, Dr. Samuel Luoma, senior research scientist at the U.S. Geological Survey.

A recent article in the NRDC's On Earth magazine explores the safety of nanosilver; you can read it here.
