Observing the Effects of Marine Debris Bioaccumulation and Biomagnification
This study examines how marine debris, particularly microplastics and heavy metals, bioaccumulates and biomagnifies through marine food webs, with organisms ingesting microplastics as they move through ocean currents. The review considers the ecological consequences of microplastic ingestion across trophic levels and the implications for food chain safety as humans sit at the top of the marine food web.
Microplastics as vectors for environmental contaminants in the food chain: Assessing the combined toxicological effects and bioavailability
This review examines how microplastics and nanoplastics act as carriers for environmental pollutants including heavy metals, organic chemicals, and microbial agents as they move through food chains. Researchers detail how polymer type, particle size, and environmental conditions influence the binding and release of these contaminants. The study highlights that the combined toxicity of microplastics together with the pollutants they carry may be greater than either would cause alone.
How microplastics interact with food chain: a short overview of fate and impacts
This review examines how microplastics move through the food chain, from water and soil into plants and animals, and ultimately into human food. Microplastics become more dangerous when they absorb toxic chemicals from the environment, and they accumulate in organisms because they take longer to pass through the body than to be consumed. The review highlights that microplastic bioaccumulation through the food web is a direct pathway for human 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 in freshwater ecosystem: bioaccumulation, trophic transfer, and biomagnification
This review synthesizes evidence on microplastic bioaccumulation and trophic transfer in freshwater ecosystems, finding that while ingestion by freshwater organisms is well-documented, biomagnification through food chains remains poorly understood and requires further investigation.
Source, migration path and pollution of microplastics and nano-plastics in food
This review traced the sources, migration pathways, and food contamination status of microplastics and nanoplastics, covering their entry into food chains through packaging, processing, environmental pollution, and water sources—and discussing potential accumulation in the human body and associated health risks.
Plastic Peril
This review examines the skyrocketing global plastic production and the resulting accumulation of microplastics that adversely affect terrestrial and aquatic organisms through bioaccumulation and biomagnification. The authors assess evidence for microplastic effects across trophic levels including in edible aquatic organisms, highlighting the food chain risks from plastic pollution.
Bioaccumulation of emerging contaminants in aquatic food chains and its implications for public health
This review synthesizes evidence on how emerging contaminants — including PFAS, microplastics, pharmaceuticals, and flame retardants — bioaccumulate through aquatic food chains, with subsistence fishing communities and coastal populations identified as the most highly exposed groups.
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.
Aquatic Ecosystem Toxicity and Food Chain
This review examines how toxic substances including heavy metals, nutrients causing algal blooms, and microplastics accumulate in aquatic food chains. Researchers describe how pollutants absorbed by bottom-dwelling organisms can concentrate as they move up through the food web to fish and eventually to humans. The study also discusses emerging remediation approaches using plants and animals to help reduce toxicity in contaminated aquatic ecosystems.
Microplastics in the food chain
This review examines how microplastics enter and move through the food chain, posing risks to animal health, human wellness, and ecosystems. Researchers found that microplastic contamination has been extensively studied in aquatic environments and marine species, but significant knowledge gaps remain regarding their accumulation and impacts in agricultural soils and plant systems. The study calls for more research on soil microplastic contamination to reduce food chain hazards.
Emerging and Persistent Food Contaminants: A Decade Review of Their Health Risks and Mitigation Strategies
This decade-long narrative review synthesized evidence on emerging and persistent food contaminants including heavy metals, pesticides, mycotoxins, microplastics, pharmaceuticals, and endocrine-disrupting chemicals. Microplastics emerged as a growing concern across the food chain, with evidence accumulating for systemic health effects via ingestion of contaminated food and water.
Microplastics in human food chains: Food becoming a threat to health safety
This review traces how microplastics enter the human food chain through both animal and plant sources, food packaging, and beverages. Once consumed, microplastics can accumulate in tissues and release harmful chemicals like plasticizers and heavy metals inside the body. The study emphasizes that food has become a major exposure pathway for microplastics and calls for stricter regulation of plastic use in food production and packaging.
A Retrospection on Mercury Contamination, Bioaccumulation, and Toxicity in Diverse Environments: Current Insights and Future Prospects
This review examines mercury contamination in the environment, its accumulation in the food chain, and its toxic effects on living organisms. Mercury exposure through contaminated crops and seafood can cause cancer, genetic damage, and disruption of enzymes and proteins in the body. While focused on mercury rather than microplastics, the research is relevant because microplastics can absorb and transport mercury and other heavy metals into organisms.
Trophic Transfer and Accumulation of Microplastics in Freshwater Ecosystem: Risk to Food Security and Human Health
This review examined the trophic transfer and accumulation of microplastics through freshwater food chains, highlighting the risks to food security and human health as plastic particles biomagnify from lower to higher trophic levels.
The Impact of Microplastic Bioaccumulation on Marine Ecosystems
This review examined the bioaccumulation of microplastics in marine ecosystems, tracing MP uptake from zooplankton to fish to marine mammals and discussing the ecological disruptions caused by plastic accumulation across food webs. It called for integrated solutions addressing MP pollution at both the source and ecosystem levels.
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.
Occurrence and Fate of Emerging Contaminants with Microplastics Current Scenario, Sources and Effects
This review chapter covers the current state of microplastic contamination across marine and terrestrial environments, explaining how microplastics act as vectors for other pollutants — including pharmaceuticals, pesticides, and heavy metals — that accumulate on their surfaces. These contaminant-laden particles are consumed by marine organisms and travel up the food chain, reaching human food sources. The work underscores that microplastics are not just a physical hazard but also a chemical delivery system that amplifies the toxic burden on ecosystems and people.
Microplastic Pollution
This review summarizes the current state of microplastic pollution across water, soil, air, and food, highlighting their ability to carry other toxins like heavy metals and PCBs. The authors note that microplastics accumulate in the food web, moving from the environment into agricultural products and eventually into the human body. The review emphasizes that a unified, comprehensive approach to studying microplastics across all environmental sources is needed to fully understand the health risks.
