An overview of microplastic in marine waters: Sources, abundance, characteristics and negative effects on various marine organisms
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.
Application of marine organisms at multi-trophic level to study the integrated biological responses induced by microplastics through food-chain
Researchers used marine organisms across multiple trophic levels to study how microplastics move and accumulate through the food chain, finding that toxicological effects intensify at higher trophic levels due to bioaccumulation of plastic particles and associated chemical pollutants.
A global perspective on microplastic bioaccumulation in marine organisms
This systematic review examines microplastic contamination in marine organisms around the world, documenting how plastics of various sizes and types build up in seafood species. Since many of these species end up on our plates, the findings raise important questions about how much microplastic humans may be consuming through seafood.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics and the chemicals they carry transfer through marine food webs from lower to higher trophic levels, and what this means for human health given that people consume marine fish and seafood. It identifies microplastics as a vector for bioaccumulation of persistent organic pollutants in ways that ultimately reach humans.
Microplastics in Marine Environment: Occurrence, Distribution, and Extraction Methods in Marine Organisms
This review summarized the occurrence, distribution, and extraction methods of microplastics in marine organisms, highlighting how these particles enter marine food webs through runoff and atmospheric deposition and pose risks to ecosystems and human health.
Microplastics in marine organism
This review examines microplastic contamination in marine organisms, systematically cataloguing data from the literature on particle counts and concentrations found in fish and other marine species. The study highlights the ecological significance of microplastic ingestion given that humans occupy the top of the marine food chain and are consequently exposed through seafood consumption.
Ecological impact of microplastic pollution on marine food webs
This review examines how microplastic pollution disrupts marine food webs, tracing the transfer of plastic particles and associated chemicals from plankton through fish to top predators and analyzing the ecological consequences for marine biodiversity and ecosystem functioning.
Microplastics and associated contaminants in the aquatic environment: A review on their ecotoxicological effects, trophic transfer, and potential impacts to human health
This review examines how microplastics and the chemical contaminants they carry move through aquatic food chains from small organisms up to larger predators. Researchers found that microplastics can transfer toxic additives and absorbed pollutants to organisms that ingest them, with potential implications for seafood safety and ultimately human health.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics move through marine food webs via trophic transfer and carry chemical contaminants that can accumulate in higher predators, including humans. Researchers found that microplastics readily sorb pollutants from surrounding waters and release them after being ingested by organisms, potentially amplifying toxic effects at each level of the food chain. The study underscores the need for more research on bioaccumulation factors and the implications of seafood-mediated microplastic exposure for human health.
Kajian Kelimpahan Mikroplastik di Biota Perairan
This Indonesian-language review summarizes research on microplastic accumulation in aquatic organisms, covering fish, invertebrates, and marine mammals from both freshwater and marine environments. Microplastics have been found in organisms across all trophic levels and all aquatic habitat types. The review provides an accessible summary of the scope of microplastic contamination in food chains relevant to human dietary exposure.
Detection of microplastics in local marine organisms using a multi-technology system
This study used multiple analytical techniques to detect microplastics in a range of local marine organisms, finding complex polymer compositions including polyethylene, polypropylene, and polystyrene across species. The multi-technology approach demonstrates the value of combining methods to accurately characterize microplastic contamination in biota.
Microplastics (MPs) in marine food chains: Is it a food safety issue?
This review examined the presence and transfer of microplastics through marine food chains, assessing food safety risks from contaminated seafood and highlighting the ability of microplastics to sorb and leach chemical contaminants that may impact human health.
Assessing the bioaccumulation of microplastics in commercially important fish species
Researchers assessed microplastic accumulation in commercially important fish species from coastal and offshore waters, finding significant differences between species based on feeding strategies and habitat depth. Filter feeders and omnivorous species accumulated more microplastics than others, reflecting diet-based differences across trophic levels. The study raises concerns about human dietary exposure to microplastics through widely consumed seafood products.
Microplastics in freshwater and marine ecosystems: Occurrence, characterization, sources, distribution dynamics, fate, transport processes, potential mitigation strategies, and policy interventions
This review summarizes research on microplastic pollution across freshwater and marine ecosystems on all six continents, finding that polyethylene and polypropylene are the most common types found in water. The study highlights that microplastics serve as carriers for toxic chemicals and can move up the food chain, ultimately posing risks to human health through seafood consumption and drinking water.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics act as vectors for chemical contaminants through marine food webs, discussing the factors influencing ingestion, the biological impacts of sorbed chemicals, and evidence for trophic transfer across multiple trophic levels. Researchers highlight that existing lab studies use unrealistically high concentrations and that no study has yet tracked microplastic-contaminant transfer from seafood to humans.
