The detection of microplastics in the gastrointestinal tracts (GIT) of marine organisms has been recognized as among a major detrimental consequence of global plastic pollution. The effect of bioaccumulation may be potentially dangerous for food web transfer and consequently for human health. Several observational studies have been carried out in a wide range of marine organisms, including decapod crustaceans, such as the shore crab and Norway lobster; however, no specific study has been assessed on the deep-water rose shrimp (Parapenaeus longistroris Lucas, 1846), an ecologically and commercially important Mediterranean crustacean. Based on this, we performed a preliminary study on the presence of microplastics in the GIT of 24 deep-water rose shrimp (DWRS) specimens, collected in the Strait of Sicily, which is among the most important fishing ground of the Mediterranean Sea. After the screening, 21% of DWRS GIT contained microplastics size range of 100 to 300 µm. Specifically, 20% of them were spherical fragments, 40% were fibres and another 40% were tangled masses of filaments. In all specimens, alien black particles (BPs) (mean diameter about 50 µm) were detected. Because the microscopical examination appeared not explanatory, different hypotheses could be formulated. We assume that these particles could be of either volcanoclastic particles (olivine -basalt phenocrysts or aggregates) related to historical/recent submarine volcanic activity that prevails in this fishing ground and or black carbon soot that had likely originated from the biomass burning and anthropogenic combustion sources, another harmful effect of the intense commercial and fishing traffic, characterising the central Mediterranean Sea.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
