"Scientists in Switzerland are reporting results of one of the first studies on the release of silver nanoparticles from laundering those anti-odor, anti-bacterial socks now on the market. Their findings, scheduled for the Nov. 1 issue of ACS' journal Environmental Science & Technology, may suggest ways that manufacturers and consumers can minimize the release of these particles to the environment, where they could harm fish and other wildlife.
 
In the study, Bernd Nowack and colleagues note that widespread use of silver nanoparticles in consumer products, especially textiles, likely results in the distribution of nanoparticles in lakes and streams. Manufacturers favor silver nanoparticles because of their antibacterial action, which slows the growth of odor-causing bacteria. The scientists studied release of nanoparticles in laundry water from nine different textiles, including different brands of commercially available anti-odor socks."
