Microplastics in commercial bivalves and their association with farm structures : A case study in a relevant aquaculture area of Brazil
(2025) In Regional Studies in Marine Science 81.- Abstract
This study investigated the presence of MPs in three species of bivalves cultivated in Brazil: Crassostrea gigas, Perna perna, and Nodipecten nodosus. Our hypothesis was that the different structures and plastic materials used in the cultivation of these bivalves could serve as a contributing source of MPs. Our results showed the presence of MPs in all species, with C. gigas showing the highest levels (4.11 ± 2.67 items ind⁻¹ and 0.078 ± 0.055 items g⁻¹), followed by P. perna (1.63 ± 0.74 items ind⁻¹ and 0.044 ± 0.025 items g⁻¹) and N. nodosus (1.44 ± 1.42 items ind⁻¹ and 0.072 ± 0.059 items g⁻¹). MPs were predominantly blue and black fibers, and synthetic polymers such as polypropylene, polyester, and rayon were identified. Elevated... (More)

MPs were predominantly blue and black fibers, and synthetic polymers such as polypropylene, polyester, and rayon were identified. Elevated levels of LABs were detected in all three bivalve species: N. nodosus (2323 ng g⁻¹) > P. perna (1787 ng g⁻¹) > C. gigas (974 ng g⁻¹), suggesting probable contamination from sewage wastewater in the cultivation areas. Contrary to our initial hypothesis, no significant amounts of MPs were found in the cultivated bivalves that could be attributed to the structures or materials used in aquaculture. These findings highlight the need for further research into external sources of MPs contamination in aquaculture environments, with particular focus on sewage wastewater contributions.
