Scientists examined microplastic contamination in the digestive tracts of five commercially important fish and shellfish species from the Persian Gulf, finding plastic particles in nearly 73 percent of all individuals sampled. Microfibers were the most common type, making up about 58 percent of particles found, and polymer analysis identified polypropylene and polyethylene as the dominant plastics. The study highlights that seafood from the Persian Gulf region is widely contaminated with microplastics, raising concerns about potential exposure for human consumers.
