Microplastics (MPs) are tiny plastic pieces that measure less than 5 millimeters (about 0.2 inches) in length. The study looked at the aging of MPs made of three common polymer chemicals—polyethylene, polyethylene terephthalate and polypropylene—to see if they changed as they aged and how that affected nearby contaminants.","pubDate":"Thu, 29 Oct 2026 22:20:01 EDT","url":"https://phys.org/news/2026-10-lab-aged-microplastics-enable-interactions.html"},"indexado":"2026-10-30T02:24:20.041Z"}}
