“…By contrast, the MP concentrations recorded in S. pilchardus were comparable to those recorded in the same species in the Adriatic Sea (4.63 items/individual), Italy (6.21 items/individual, Trani et al [58]), and Spain (8.62 items/individual, Sánchez-Guerrero-Hernández et al [59]). Differences between MP abundances recorded in the Moroccan Mediterranean Sea compared to other studies may be due to several factors.…”

“…Moreover, this study highlighted that small MPs were the most dominant in all three species (0.5-1 mm), as previously reported by Bellas et al [68] in fish species from the Spanish Mediterranean and Atlantic coasts, and Filgueiras et al [54] in pelagic and benthic fish from the northwestern Iberian Plateau. The average size of MPs obtained in the Gulf of Cadiz by Sánchez-Guerrero-Hernández et al [59] was 0.92 mm for sardines and 0.88 mm for anchovies. Similarly, Lopes et al [69] observed the dominance of the size class below 0.50 mm, while Filgueiras et al [54] reported slightly higher average sizes (i.e., 1.46 mm for sardines), and the most common size class was 0.5-1 mm.…”

Monitoring the ingestion of microplastics (MPs) by marine organisms in the environment is essential for understanding the threats posed by these pollutants. In this study, we assessed, for the first time, the presence of MPs in the digestive tracts of two fish species, Chelon auratus and Sardina pilchardus, as well as a bivalve species, Callista chione, in the Moroccan Mediterranean Sea. Moreover, we calculated the polymeric hazard index (PHI) to verify the hazard level of isolated polymers. The results showed that all species ingested MPs, indicating a high level of MP pollution in this area. The MPs ingested were predominantly small (0.5–1 mm) and had a fiber-like shape. The results showed that PP and PET were the most abundant polymers ingested. The highest occurrence of MPs (100%) was found in C. chione and C. auratus, followed by S. pilchardus (72%). In C. chione, the average number of ingested MPs was 19.19 items per individual, while in C. auratus, the mean abundance of ingested MPs was 16.82 items per individual, and 9.64 items per individual in S. pilchardus. Moreover, the polymer hazard index showed that PET was in hazard level IV, while PP was in level III. Further studies are required in the Moroccan Mediterranean Sea to obtain a better evaluation of the occurrence, distribution, and impacts associated with MP pollution.

“…Moreover, textile dyes can enter the food chain, undergoing bioaccumulation and biomagnification [23,24]. From this perspective, the analysis of anthropogenic microparticles (hereafter AMs), including MPs and MFs (synthetic, semi-synthetic and anthropogenically modified cellulose), might allow the environmental assessments and the comparison of concentrations across different studies [14,[25][26][27][28].…”

Despite the widespread presence of anthropogenic microparticles (AMs) in beach sediments, research on their occurrence on Moroccan Mediterranean beaches is still limited. This study is the first report on AM pollution in four sandy beaches along the Tetouan coast (Morocco Mediterranean). The findings reveal an average AM concentration of 483.12 ± 157.04 AMs/kg of beach sediment. The most common AM types were fibers (75.54%) and fragments (24.06%). AMs were predominantly black, red, and blue, measuring between 0.1 and 1 mm. The evaluation of the anthropogenic microparticles pollution index (AMPI) and the coefficient of anthropogenic microparticles impact (CAMI) for the study area indicated a “very high abundance” of AMs and an “extreme” level of impact. The polymers identified in these areas included PS, PE, PP, and PET. Tourism, fishing, domestic activities, and poor solid waste management practices are the primary sources of AM pollution in this region. To protect Moroccan beaches, the implementation of a consistent plastic waste management strategy is recommended.

Microplastic pollution threatens some of the world's most iconic locations for marine biodiversity, including the remote Galápagos Islands, Ecuador. Using the Galápagos penguin (Spheniscus mendiculus) as a sentinel species, the present study assessed microplastics and suspected anthropogenic cellulose concentrations in surface seawater and zooplankton near Santa Cruz and Galápagos penguin colonies (Floreana, Isabela, Santiago), as well as in penguin potential prey (anchovies, mullets, milkfish) and penguin scat. On average, 0.40 ± 0.32 microplastics L−1 were found in surface seawater (<10 μm; n = 63 L), while 0.003, 0.27, and 5.12 microplastics individual−1 were found in zooplankton (n = 3372), anchovies (n = 11), and mullets (n = 6), respectively. The highest concentration (27 microplastics individual−1) was observed in a single milkfish. Calculations based on microplastics per gram of prey, in a potential diet composition scenario, suggest that the Galápagos penguin may consume 2881 to 9602 microplastics daily from prey. Despite this, no microplastics or cellulose were identified in 3.40 g of guano collected from two penguins. Our study confirms microplastic exposure in the pelagic food web and endangered penguin species within the UNESCO World Heritage site Galápagos Islands, which can be used to inform regional and international policies to mitigate plastic pollution and conserve biodiversity in the global ocean.
