| Descrizione: | Introduction: In mangroves, microplastics (MPs), (< 0.5 mm particles) penetrate deep into the sediments and can cause adverse effects on the species that consume them by accident, affecting their development, nutrition, and life quality in general. In Colombia, studies on plastic and microplastic pollution have been focused on the Caribbean coast and its consumption by fishes, however, the Pacific has been scarcely documented. Objective: To confirm the presence of MPs in mangrove organisms of two locations of Buenaventura Bay, Colombia, to characterize them, and to estimate their effect on trophic groups. Methods: Two species of cockles, Anadara similis and Anadara tuberculosa, and crab Goniopsis pulchra were selected. MPs were extracted, counted, and classified according to shape and color. Results: In total, 81 individuals were captured. We found MPs in 100 % of the organisms and transparent fragments were the most abundant (56.40 %). An average of 25.54 ± 23.8 particles/individual was found, and no differences were found between the cockles, but between each regarding G. pulchra. Conclusion: The different feeding behaviors could explain these differences; more generalist species would ingest a more significant amount of particles. This is the first approximation to studying MPs inside invertebrate organisms in the Colombian Pacific. |
