10 Oct 2023 --- A new study compares the ecotoxicity of microplastic polyethylene (PE) and naturally sourced microcrystalline cellulose microbeads, both extracted from cosmetic products. The research investigates the influence of the two types of particles on aquatic plants, including common duckweed and planktonic crustacean, alongside the bioadhesion of the particles to common duckweed. Microbeads made from plastics are added to cosmetic products to add an abrasive texture to scrub the skin. These beads, after application, are washed down the drain, allowing microplastics to leak into the world’s waterways.
