Environmental 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.
A Comprehensive Review on Metallic Trace Elements Toxicity in Fishes and Potential Remedial Measures
This review examines how toxic trace metals such as mercury, cadmium, lead, and arsenic accumulate in fish and damage their neurological, reproductive, and developmental systems.

The study also discusses potential remediation approaches, including bioremediation and nanotechnology, to reduce metal contamination in aquatic environments.
Interactions Between Microplastics and Heavy Metals in Aquatic Environments: A Review
This review examines how microplastics interact with heavy metals in water, with a particular focus on the role that microorganisms play in driving these interactions. Bacteria that colonize microplastic surfaces can change how metals bind to and release from the particles, potentially increasing their toxicity. The combined threat of microplastics and heavy metals to aquatic ecosystems and human health through seafood consumption is a growing concern that needs more research.
The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
This review examines how microplastics and heavy metals interact in water environments, finding that microplastics can attract and concentrate toxic metals on their surfaces through various chemical forces. This combination effect is a concern for human health because contaminated microplastics carrying heavy metals can be consumed through seafood, delivering a double dose of pollutants.
Microplastics on the frontline: causes, strategies to combat pollution and protect health with advanced bioremediation—a review
This systematic review examines how microplastics carry toxic chemicals like heavy metals and persistent pollutants into the food chain, ultimately reaching humans. It also explores promising bioremediation approaches — using bacteria and enzymes to break down microplastics — as a potential strategy to reduce exposure.
Interactions and effects of microplastics with heavy metals in aquatic and terrestrial environments
This review explores how microplastics absorb toxic heavy metals from the environment and what happens when organisms ingest these contaminated particles. In the acidic conditions of an animal's digestive system, metals can separate from the plastic and accumulate in body tissues. Since heavy metals can concentrate on microplastics and then transfer up the food chain, this combination poses a compounded health risk to wildlife and potentially to humans who eat contaminated 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.
Interaction of Microplastics and Heavy Metals on Aquatic Organisms : A Review
This systematic review examines how microplastics interact with heavy metals in waterways, finding that plastic particles absorb toxic metals and then release them inside organisms that ingest them. This combination increases the toxicity of both pollutants, leading to DNA damage, tissue changes, and reproductive problems in aquatic life, with potential consequences for human health through the food chain.
Bioaccumulation and Biomagnification (The Subtle Processes that Question our Survival)
This review synthesizes mechanisms of bioaccumulation and biomagnification in aquatic ecosystems, examining how heavy metals, microplastics, and other toxicants concentrate up food chains and pose escalating risks to ecological balance and human health.
An insight into the ecological risks and mitigation of heavy metal pollution in aquatic sediments and marine ecosystems
This review examines heavy metal pollution in aquatic sediments and marine ecosystems, covering contamination sources, ecological risks, and mitigation strategies. The study highlights the deterioration of aquatic zones due to rising pollution from urbanization and industrialization, and discusses how pollutants including microplastics interact with heavy metals to affect biogeochemical cycling and the food chain.
Factors Affecting the Adsorption of Heavy Metals by Microplastics and Their Toxic Effects on Fish
This review examines how microplastics absorb heavy metals from water and how the combined pollution harms fish. Factors like water pH, temperature, and the age of the plastic all affect how much metal sticks to the surface. Since fish are a major protein source for humans, the combination of microplastics and heavy metals entering fish tissue is a potential pathway for these pollutants to reach people through their diet.
The role of microplastics biofilm in accumulation of trace metals in aquatic environments
This review examines how biofilms that form on microplastics in aquatic environments enhance the accumulation of trace metals from surrounding water. Researchers found that microorganisms colonizing plastic surfaces produce extracellular substances that facilitate metal sorption, effectively turning microplastics into concentrated carriers of metallic contaminants. The study highlights the dual pollution risk posed by microplastics serving as both physical pollutants and vehicles for toxic metal transport in waterways.
[Research Progress on Trojan-horse Effect of Microplastics and Heavy Metals in Freshwater Environment].
This review examines the Trojan-horse effect in freshwater environments where microplastics adsorb and transport heavy metals, significantly increasing their potential ecological harm due to the large surface area and persistence of microplastic particles.
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.

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.
Heavy Metal Pollution in Coastal Environments: Ecological Implications and Management Strategies: A Review
This review examines heavy metal pollution in coastal environments, covering sources like industrial runoff and agriculture, ecological impacts, and cleanup strategies. While focused on heavy metals rather than microplastics, it is relevant because microplastics often carry heavy metals on their surface, potentially increasing human exposure to these toxic substances through the food chain.
