Scientists developed a new method to accurately measure tiny plastic particles trapped in underwater reefs built by marine worms. These reef structures act like filters that collect microplastics from ocean water, which can then enter the food chain when other sea creatures eat organisms living on the reefs. This improved testing method will help researchers better track plastic pollution in coastal waters and understand how it might affect seafood that people eat.
