"Smaller than a virus and used in more than 200 consumer products, silver nanoparticles can kill and mutate fish embryos, new research shows. Tiny particles of silver – potent anti-microbial agents that can kill bacteria on contact – are becoming increasingly popular in consumer goods, including washing machines, refrigerators, clothing and toys. Many nanoparticles, including nanosilver, wash down drains and are discharged into lakes and rivers, where fish and other aquatic life are exposed."
