The little things are a big problem
Microplastics are pieces of plastic up to 5mm, which is about the width of a pencil eraser. They include pieces broken down from larger pieces, microbeads, microfibers, and nurdles. Microbeads are manufactured for health and beauty products. Microfibers shed off our clothing. Small resin pellets, or nurdles, are how plastic is transported to various companies before being turned into products.
Good news on one microplastic type. Microbeads have been banned in the United States and the European Union. This stops the production and the flow of these materials into our environment.
Nanoplastics are so small they cannot be seen with the naked eye, less than the width of a human hair, and require special microscopes to see. Most of the nanoplastics we are exposed to come from food and beverage containers. See the links to learn more about the impacts of micro and nanoplastics on human health.
