- The use of silver as a germicide in clothing can have very serious consequences. The limited silver resources can be put to work and therefore silver in clothing should be banned, say the Nanosphere-affiliated researchers Richard Arvidsson, Sverker Molander and Bjorn Sandén in an article in the Swedish newspaper Svenska Dagbladet.

The relatively rare metal has been used by mankind for a long time for its line of coveted properties. Recently, silver toxicity to bacteria have started to been used not only in antibacterial patch but also in workout clothes, shoes and similar products. The idea is that the silver, often in the form of extremely small particles, called nanoparticles, can kill bacteria and reduce odors.

- Unfortunately, silver is not only toxic to the bacteria that cause bad odors but also for many aquatic organisms (primarily some micro algae and crustaceans). The use of silver in textiles inevitably leads to the release of silver in the environment, mainly by washing the silver in textiles comes off fairly easily. Such use can have serious consequences for the environment, according to the researchers.

Therefore, they believe that it is urgent to acquire new knowledge and parallel update and extend the law.
