ClearEnvironmental Contaminants in Fish Products: Food Safety Issues and Remediation Strategies
This review provides an overview of environmental contaminants found in fish products, including heavy metals, persistent organic pollutants, and microplastics, and their risks to human health through seafood consumption. The combined presence of multiple contaminants in fish can create compounding toxic effects that are greater than any single pollutant alone. The authors recommend better monitoring and cleanup strategies, including bioremediation, to protect both marine ecosystems and the people who eat seafood.
Risks Associated with Dietary Exposure to Contaminants from Foods Obtained from Marine and Fresh Water, Including Aquaculture
This review examines the risks of dietary exposure to contaminants from aquatic foods including fish, shellfish, and microalgae, covering persistent organic pollutants, heavy metals, PFAS, and microplastics. Researchers note that while aquaculture helps address overfishing, both wild and farmed aquatic food systems face contamination from agricultural runoff, industrial discharges, and domestic effluents. The study highlights the need for robust monitoring to protect food safety as aquatic food production continues to expand.
Potential Effects of Persistent Organic Contaminants on Marine Biota: A Review on Recent Research
This review examined the effects of persistent organic contaminants including microplastics, pharmaceuticals, pesticides, PCBs, and PAHs on marine biota, synthesizing evidence of direct and indirect ecological impacts across multiple chemical classes.
Risks Associated with Dietary Exposure to Industrial and Geological Contaminants from the Consumption of Foods Obtained from Marine and Fresh Water, Including Aquaculture
This review examines dietary exposure risks from industrial and geological contaminants in marine and freshwater foods, including microplastics, heavy metals, and persistent organic pollutants, covering both wild-capture and aquaculture sources.
Bioaccumulation of persistent organic pollutants and trace metals in Scottish marine food webs and their relationship with trophic level and fatty acid signatures
Researchers measured persistent organic pollutants and trace metals in Scottish marine food webs, finding that levels increased with trophic position. The study supports using fatty acid signatures as a tool to trace contamination pathways in marine ecosystems.
Fish liver damage related to the wastewater treatment plant effluents
Researchers reviewed how the complex chemical mixture discharged by wastewater treatment plants damages fish liver structure and function, examining how biotransformation enzymes and antioxidant systems attempt to cope with persistent contaminants and highlighting fish biomarkers used to detect exposure.
Impact of polyvinyl chloride microplastic exposure on the hepatopancreas metabolism of Pinctada fucata martensii: Insights from metabolomics
Researchers exposed pearl oysters to PVC microplastics and used metabolomics to track changes in the animals' liver-like organ. They found that microplastic exposure disrupted amino acid and lipid metabolism, with signs of potential neurotoxicity and oxidative damage, demonstrating that common plastic pollutants can meaningfully alter the biological processes of shellfish.
Bioaccumulation of Different Organic Micropollutants in Fishes and its Toxicological and Stress Impacts: A Review
This review covers how organic micropollutants including pesticides, pharmaceutical compounds, and industrial chemicals bioaccumulate in fish and examines their toxicological effects on fish physiology, immune function, and reproductive health.
Chemical cues for intraspecific chemical communication and interspecific interactions in aquatic environments: applications for fisheries and aquaculture
This review explores how aquatic organisms use chemical cues for communication, mating, feeding, and danger detection, and how this knowledge applies to aquaculture and fisheries. Researchers noted that global environmental changes, including ocean acidification and increasing plastic pollution, can disrupt these chemosensory behaviors. The study discusses practical applications such as using pheromones to improve breeding success and developing low-cost attractants for sustainable fishing.
Impact of Pollution and Toxic Stress on Fish Health: Mechanisms, Consequences, and Mitigation Strategies
This review examined the many ways pollution and toxic substances harm fish health, including through disrupted metabolism, hormonal imbalances, weakened immune systems, and reproductive problems. The study highlights that pollutants enter fish through water, food, and sediment, and discusses mitigation strategies for protecting fish populations and the broader aquatic ecosystems they support.
Health benefits of fish and fish by-products—a nutritional and functional perspective
This review highlights the nutritional benefits of fish as a source of protein, omega-3 fatty acids, and bioactive compounds that protect against cardiovascular disease, inflammation, and neurological disorders. However, it also notes that some fish species are contaminated with harmful substances, which is relevant given that microplastics in aquatic environments can accumulate in fish and transfer toxins up the food chain.
The influence of ecological factors in the modulation of pollution biomarkers of two small pelagic marine fish
Researchers examined how ecological factors such as body condition, sex, and season modulate pollution biomarker responses in two small pelagic fish species, finding that biological variability must be accounted for when using hepatic biomarkers to assess marine contamination levels.
Environmental contaminants of emerging concern in seafood – European database on contaminant levels
Researchers compiled a European database on contaminants of emerging concern found in seafood, including substances without established regulatory limits. The study documents the growing concern about chemical transfer from marine environments to food, covering a range of emerging contaminants that may interact with microplastic pollution in aquatic ecosystems.
Physiological impacts of microplastics, heavy metals, and metallothionein in milkfish (Chanos chanos) in Jakarta Bay, Indonesia
Researchers analyzed concentrations of microplastics, metallothionein, and heavy metals in milkfish (Chanos chanos) sampled from Jakarta Bay, Indonesia, to assess how anthropogenic activities contribute to combined microplastic and heavy metal contamination in commercially important coastal fish.
From ocean to table: marine contaminants and their risks to human health and biodiversity
This review synthesized current knowledge on marine pollutants—including microplastics, heavy metals, POPs, and pathogenic microorganisms—their ocean transport pathways, trophic transfer up food chains, and risks to human health through seafood consumption. The authors found that plastic-associated chemical contaminants are now detectable in commercially important seafood species globally, with implications for food safety regulations.
Toxicological implications of emerging pollutants on aquatic organisms
Researchers reviewed how a broad range of emerging pollutants — including microplastics, pharmaceuticals, pesticides, and heavy metals — harm aquatic organisms like fish, amphibians, and molluscs. Evidence shows these pollutants trigger oxidative stress, disrupt hormones, impair reproduction, and reduce biodiversity, with the review calling for stronger regulations, better wastewater treatment, and more research on the combined effects of multiple pollutants.
Role of Environmental Pollution in Altering Reproductive Cycles in Freshwater Fishes
Not relevant to microplastics — this review examines how industrial chemicals, pharmaceuticals, heavy metals, and pesticides in freshwater ecosystems disrupt reproductive cycles in fish, covering hormonal imbalances and population effects from endocrine-disrupting chemicals broadly.
The Effects of Co-Exposure to Antifoulants and Microplastics on the Survival, Oxidative Status, and Cholinergic System of a Marine Mysid
Researchers investigated how microplastics affect the toxicity of antifoulant chemicals copper pyrithione and zinc pyrithione in aquatic environments, where the presence of plastic particles can alter chemical behavior and bioavailability. Results showed microplastics introduce significant uncertainty into the toxicological assessment of these widespread aquatic pollutants.
