Microplastics in marine biota: A review
AI summary Read the abstract
This review analyzed 132 studies from 2010 to 2020 on microplastic contamination in marine animals. Researchers found that sea turtles were the most affected group, with 88% of specimens contaminated, and that fibers and fragments were the most common microplastic shapes, with blue and transparent particles being predominant across marine species.
Plastics are the most important component in marine debris. In turn, within plastics, microplastics (<5 mm) are those that most affect marine biota. Thus, this review has as its main objective to show the current state of studies of microplastics, as well as to determine the groups of vertebrates most affected by microplastics, and the type and predominant color of microplastics. For this research, we review a total of 132 articles, from 2010 to May of 2020. Our results show that the group more affected are turtles with 88% of the specimens contaminated by microplastics and median of 121.73 particles/individue. The predominant type is fibers (67.3%), polymer is polyethylene (27.3%), size is less than 2 mm (73.6%), and color is blue (32.9%).

An overview of microplastic in marine waters: Sources, abundance, characteristics and negative effects on various marine organisms
AI summary Read the abstract
This review summarizes existing research on microplastic pollution in the world's oceans, covering where microplastics come from, how abundant they are, and their harmful effects on marine life from tiny plankton to sea turtles and seabirds. Microplastics have been found in organisms at every level of the ocean food chain, with the most common types being polyethylene and polypropylene fragments and fibers. The widespread contamination of marine life raises direct concerns for human health, since many of these organisms end up as seafood on our plates.
Microplastic ingestion ubiquitous in marine turtles
AI summary Read the abstract
Researchers examined over 100 marine turtles across all seven species and found synthetic particles in every single individual tested. The study suggests that microplastic ingestion is ubiquitous across marine turtle species, regardless of geographic location or life stage, raising broad concerns about plastic contamination in large marine vertebrates.
Literature Review: Identifikasi Mikroplastik Terhadap Lingkungan Laut Dan Biota Laut
AI summary Read the abstract
This literature review examines five studies on microplastic identification in Indonesian marine environments and biota, characterising abundance, morphology, and polymer type. The review found that fiber and fragment shapes predominate, polystyrene and polycarbonate are the dominant polymers, and microplastic abundance correlates with local population density and human activity, with ingestion by marine organisms posing risks to food chains and human health.
Microplastics in coastal and oceanic surface waters and their role as carriers of pollutants of emerging concern in marine organisms
AI summary Read the abstract
Researchers analyzed 167 studies on microplastics in ocean surface waters and marine organisms, finding that fragments and fibers are the most common particle types across all regions studied. The review highlights that microplastics act as carriers for other harmful pollutants, increasing the chemical burden on marine life. The uneven global distribution of research means that microplastic contamination in many ocean regions remains poorly understood.
Literature Review : Determination Of Microplastic Content In Seafood?
AI summary Read the abstract
This literature review synthesized findings from seven observational studies on microplastic contamination in seafood, specifically fish and bivalves from marine environments. A total of 421 microplastic particles were found in bivalves and 386 in fish across the reviewed studies, with fiber type dominating at over 86–90% of particles in both organism types. The digestive system was the most common site of microplastic accumulation, highlighting contamination risks for seafood consumers.
