Once washed down the drain, the silver particles enter the environment where they may pose numerable unknown adverse effects. Researchers from Arizona State University report their findings in a study entitled; \u201cFate and transport of ionic and nanoparticle silver released from commercially available socks,\u201d published in Environmental Science and Technology. Six commercial brands of nanosilver-treated socks were tested and their nanosilver content measured before and after wash. The socks were soaked in 1- or 24-hour-long wash cycles in distilled water without detergent to limit variables in the tests. One batch was soaked in tap water to simulate a more realistic washing.Using scanning and transmission electron microscopy, the remaining silver was analysed. Under the microscope, nanoparticles were found clumped together in the fabric, while some socks had tiny corkscrew-shaped nanosilver particles that stuck like burrs to the fabric, clinging more tightly than some simpler nanosilver forms. They found that socks had variable leaching rates, which suggests that the sock manufacturing process and how they are impregnated with silver may influence the release of silver. In [&hellip;]"}
