Bioaccumulation of Plastics in Fish Raises Health Concerns and Regulatory Gaps
AI summary Read the abstract
Researchers reviewed how microplastics bioaccumulate in fish through ingestion and gill uptake, tracing pathways from aquatic environments into the food chain and highlighting regulatory gaps that leave human health risks from consuming contaminated fish largely unaddressed.
Microplastic pollution represents a significant and growing environmental threat to aquatic ecosystems and human health. This chapter comprehensively reviews the bioaccumulation of microplastics in fish, exploring their sources, pathways, and potential toxicological...

Impact of Plastic Waste Ingestion by Fish
AI summary Read the abstract
This review synthesized experimental evidence on how microplastic ingestion affects fish physiology and behavior, finding that plastics act as vectors for toxic chemicals including mercury, cause oxidative stress, and transfer contaminants up the food chain to human consumers. Because microplastics bioaccumulate through trophic levels, populations relying heavily on seafood—particularly from coastal regions—face compounded exposure risks that extend well beyond the plastic particles themselves.
Microplastics in Fish: An Emerging Environmental Challenge
AI summary Read the abstract
This review synthesized evidence on microplastic bioavailability and accumulation in fish species globally, examining ingestion routes, tissue distribution, and potential health effects on both fish and human consumers. As a major dietary protein source for billions of people, fish contaminated with microplastics represent a direct and quantifiable pathway for human exposure to plastic particles and their adsorbed chemical pollutants.
Plastic Debris Alters Aquatic Habitats and Disrupts Sustainable Fisheries
AI summary Read the abstract
Researchers reviewed how plastic debris infiltrates aquatic ecosystems, fragmenting into micro- and nanoplastics that disrupt fish habitats, alter food webs, and undermine sustainable fisheries. This matters because plastics' persistence in water means microplastics accumulate in seafood consumed by humans, linking ocean pollution directly to food safety and long-term health exposure.
Effects of plastics and microplastics on aquatic organisms and human health
AI summary Read the abstract
This review paper pulls together existing research showing that tiny plastic particles called microplastics are ending up in fish, mussels, shrimp, and other seafood we eat. Because these creatures absorb microplastics from polluted water, the plastic can travel up the food chain and onto our plates, meaning our growing use of plastic may be quietly working its way into our diets. The authors call for more public awareness and action to reduce plastic pollution before its full health effects on people are better understood.
Microplastics' Dangers to Humans and Ecosystems
AI summary Read the abstract
Researchers reviewed the global dangers of microplastics to human health and ecosystems, characterizing these particles as a pervasive pollutant with the potential to cause widespread harm across multiple environmental compartments and biological systems.
