A single load of laundry can shed more than 700,000 microscopic plastic fibers into water systems, according to a recent study in the journal Marine Pollution Bulletin. Many of these tiny plastic particles make it through sewage treatment plants and enter aquatic ecosystems such as rivers, lakes, wetlands, and oceans. The study looked at the breakdown of polyester, acrylic, and polyester-cotton fabrics washed in 86-104 degree Fahrenheit water with various detergents. It found that a 13-pound load of polyester-cotton laundry shed an estimated 137,951 plastic fibers, a load of polyester clothing 496,030 fibers, and acrylic fabric 728,789 fibers. Microplastic particles in waterways are often mistaken for food and eaten by marine life, with various health impacts. The research was conducted by scientists at Plymouth University in England.
