Microplastics in the Food Chain
This review documents microplastic presence throughout the food trophic chain, examining how plastics enter food webs, accumulate with biomagnification, and affect organisms at each trophic level including humans who are at the top of the chain.
Microplastic profusion in food and drinking water: are microplastics becoming a macroproblem?
This review examined the prevalence of microplastics in food and drinking water, assessing trophic transfer along the food web and evaluating whether microplastic contamination in human dietary sources constitutes a growing public health concern.
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.
Gathering at the top? Environmental controls of microplastic uptake and biomagnification in freshwater food webs
This review examines the uptake and potential biomagnification of microplastics through freshwater food webs, from primary producers to top predators. Researchers found that while microplastics accumulate in organisms at multiple levels of the food chain, evidence for true biomagnification remains limited and inconsistent. The study identifies key environmental and physical factors that control microplastic exposure pathways and calls for more standardized field studies to resolve whether microplastics concentrate up the food chain.
How Do Microplastics Distribute Through Freshwater Ecosystems? Which Biota, Feeding Groups, and Trophic Levels Are Most at Risk?
This review examines how microplastics distribute through freshwater ecosystems — across water columns, sediments, biota, and trophic levels — identifying filter feeders, detritivores, and higher trophic level organisms as particularly vulnerable to microplastic accumulation.
Trophic transfer of microplastics in zooplanktons towards its speculations on human health: A review
This review examines how microplastics move through the ocean food chain, from tiny zooplankton at the base up through fish to humans, and what health effects may result. Trophic transfer means microplastics can concentrate as they move up the food web, increasing human dietary exposure.
Describing the Accumulation, Concentration, and Amplification Effects of MPs Through the Food Chain
This review examines evidence for microplastic accumulation, concentration, and amplification through food chains from primary producers to predators. The authors discuss the degree to which trophic transfer leads to biomagnification of plastic particles and co-adsorbed chemical contaminants, with implications for wildlife and human dietary exposure.
Microplastic contamination across trophic levels in a lowland spring watercourse of Northwestern Italy: New insights and biomonitoring implications
Microplastic contamination was measured across trophic levels (algae, invertebrates, fish) in a lowland river ecosystem, finding that concentrations increased in organisms at higher levels of the food web. The trophic transfer data suggest that microplastics bioaccumulate through freshwater food chains.
The Challenge of Microplastics in Aquatic Ecosystem: A Review of Current Consensus and Future Trends of the Effect on the Fish
This review synthesizes research on how microplastics affect aquatic ecosystems, covering ingestion by marine animals, trophic transfer up the food chain, and the chemicals that microplastics carry. The findings highlight that microplastic contamination is now widespread enough to threaten marine biodiversity and food security for populations that rely on seafood.
Intrusion of Mercury and Micro Plastics in the Aquatic Food Chain Its Effects on Fish Consumption Risks, Realities, and Policy Implications
This review examines how mercury and microplastics contaminate aquatic food chains, focusing on biomagnification of mercury across trophic levels and the ingestion and tissue accumulation of microplastics by fish. It discusses food safety risks for human consumers and policy implications for managing co-occurring aquatic pollutants.
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.
A Summary of the Transporting Mechanism of Microplastics in Marine Food Chain and its Effects to Humans
