Contamination from Antibacterial Nanosilver Sparks Efforts to Contain It

(Beyond Pesticides, March 29, 2018) Rising use of antibacterials like nanosilver in textiles and other consumer goods is leading scientists to consider methods to filter out these materials before they pollute the environment. As detailed by research published in Sustainable Chemistry and Engineering, experts at University of Massachusetts, Dartmouth, are developing a process to filter out these toxic materials from our washing machines. While preventing downstream waste is laudable, it misses the fundamental question whether nanosilver and other antibacterials need to be added to consumer clothing in the first place. Nanosilver is antimicrobial nanoparticle (typically defined as a particle between 1-100 nanometers) regulated as a pesticide that is added to consumer goods such as textiles, cosmetics, disinfectants, toys and other household items in attempts to kill bacteria or reduce odor. See the Project on Emerging Nanotechnologies for an extensive listing of products containing nanoparticles on the market. Nanosilver, which makes up roughly 25% of nanomaterials used in the consumer market, is a particularly concerning nanoparticle given past research on its risks to health and the environment. Studies have found that, when impregnated into textiles like sportswear, nanosilver does not just wash out in the washing machine, it can also seep […]
