We report the presence of microplastics on the external surface and in the gastrointestinal tract of white latelarval and juvenile stages (fry) of clupeid fishes caught in the Southern Tyrrhenian Sea. The average highest number of plastics debris was recorded on Sardina pilchardus (0.53 items/specimen): a lower average number of items was observed for Engraulis encrasicolus (026 items/specimen). The plastics were characterized by fibers that differed in shape, colour and composition. Polyester, polypropylene, polyaa ylonitrile. polyethylene, polyamide, nylon, rayon and polyurethane segments were detected by Raman and MR spectroscopies. Traces of organic components and dyes, compounds that are generally included in the polymer matrix to modify its base properties, were also identified on miaoplastics. Our results raise concerns for the potential transfer of synthetic materials through the marine food web and into humans, given the prominent role of S. pilchardus and E. encrasicolus within the food web as main food source for many marine species.
