Microplastics in seafood: study of different fish transformation process in the frame of contamination mitigation

Résumé

Aim: Microplastics (MPs) have been detected in numerous fish species, yet the presence of MPs in filets or transformed seafood products has received only a limited attention in scientific research. Moreover, from these few studies, they only focused on end-products. The aim of this study was to gather comprehensive data from different processes and their steps, finally comparing them in order to estimate flow of MPs throughout process in order to provide recommendations. Materials & Methods: All samples collected during the different process were treated using the usual methodology: digestion with 10% KOH at 40°C for 24h, filtration on 90 mm GF/A 1.6 µm pore size filters, characterization of particles using stereomicroscope and FT-IR spectroscopy. Data have then were corrected regarding the contaminations that occurred during analyses in the laboratory. Using these corrected data, a comparative analysis was carried out for the whole processes to identify potential sources of contamination. Results and Discussions: The results varied depending on the specific process studied, making it impossible to establish a standardized pattern. Across processes, some steps help to reduce the quantity of some MPs. Regarding the sources of contamination, some were clearly identified for some processes, while for others it remains more difficult to characterize. Conclusions: The examination of various seafood product transformation processes provided a comprehensive understanding of the contamination levels of MPs throughout their different steps. This help to have a better knowledge of MP flows, and will contribute in elaborating some recommendation on good practices in order to mitigate the quantities of MP in seafood products.
