Presencia de microplásticos en peces pelágicos de mayor comercialización, en el mercado de “Playita Mía” de la ciudad de Manta
AI summary Read the abstract
Researchers found microplastics in three commercially sold fish species at a market in Manta, Ecuador, including tuna, a lookdown fish, and a sea bass species. The presence of microplastics in widely consumed food fish raises concerns about dietary exposure for the local population.
The research consisted of evaluating the presence of microplastics in pelagic fish of greater commercialization, in the market of Playita Mia in Manta city. For this, the three most consumed species Thunnus alalunga (Albacora), Selene peruviana (Carita) and Diplectrum conceptione (Camotillo) were identified, through surveys carried out on site workers. A sample was taken from 120 individuals divided into the three aforementioned species, in which a characterization of the microplastics presented in the gastrointestinal tract was performed by their color, morotype and size. In addition, the concentration of microplastics was determined, in which a separation by morphology of the species was carried out, in which the quantification of these was carried out, where 760 pieces of microplastics were found, in the individuals examined, with an ingestion rate of 76% average. Thunnus alalunga had a high rate of Microplastic ingestion of more than 80%, however, there was no significant difference when compared to the other species.
