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.
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.
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.
A Summary of the Transporting Mechanism of Microplastics in Marine Food Chain and its Effects to Humans
This review summarized how microplastics are transported through marine food chains from plankton to fish to humans, detailing toxic effects at each trophic level and outlining mitigation strategies to reduce ecological and human health risks from oceanic plastic pollution.
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.
Microplastic Contamination in the Marine Food Web
This review examines the contamination of the marine food web by microplastics, tracing the pathways by which plastic particles enter and move through trophic levels from primary producers to top consumers including marine mammals and humans, and summarizing evidence for toxicological effects and human exposure through seafood consumption.
Bioaccumulation and biomagnification of microplastics in marine organisms: A review and meta-analysis of current data
This meta-analysis reviews current evidence on whether microplastics accumulate and concentrate as they move up the marine food chain. The findings have direct implications for seafood safety, since biomagnification would mean that larger predatory fish consumed by humans could contain higher concentrations of microplastics and their associated chemical additives.
Microplastics in the Food Chain
This review summarizes evidence for microplastic entry and accumulation throughout the food chain, from environmental sources through plant uptake, invertebrate ingestion, fish accumulation, and ultimately human consumption.
