Does aquatic sediment pollution result in contaminated food sources?
Summary
This review examined how aquatic sediment contamination by chemicals, heavy metals, and microplastics can transfer into fish and shellfish used for human food. Microplastics and their associated chemical pollutants accumulate in seafood tissues, creating a direct human dietary exposure pathway.
The sediment pollution of the aquatic environment by waste due to anthropogenic activity is of an increasing concern. The contaminants coming from the aquatic environment can enter the aquatic food chain and accumulate in the tissues of fish and shellfish used for human consumption. The aim of this study was to sum up the current level of knowledge concerning the pollution of aquatic sediments and its transfer to aquatic foods as well as to indicate whether such contamination has the potential to affect the health and welfare of aquatic organisms as well as the quality and safety of the species intended for human consumption. Based on the results of scientific studies, the European Food Safety Authority, and the Rapid Alert System for Food and Feed, contamination of fish and seafood occurs predominantly through their diet and the levels of bioaccumulative contaminants are higher in fish which rank higher in the food chain. Contamination of aquatic habitats can not only significantly affect behavior, development, and welfare of aquatic organisms, but it can also affect the safety of fish and seafood for human consumption.

Challenges to Aquatic Food Source Sustainability: Investigating the Bioaccumulation of Microplastics of Tilapia and Mussels
This study investigated microplastic bioaccumulation in aquatic food sources including fish, shellfish, and crustaceans, examining contamination levels across commercially important species and assessing the human dietary exposure implications of consuming aquatic foods from contaminated environments.
Microplastics—A New Threat to Aquatic Food Safety?
This review article examines whether microplastics pose a new threat to the safety of aquatic food sources, noting that plastics have accumulated widely in marine environments and are ingested by organisms throughout the food chain. The authors assess potential risks from microplastic particles in seafood and the possibility of chemical contaminants being transferred from plastic to human consumers.
Microplastics and associated contaminants in the aquatic environment: A review on their ecotoxicological effects, trophic transfer, and potential impacts to human health
This review examines how microplastics and the chemical contaminants they carry move through aquatic food chains from small organisms up to larger predators. Researchers found that microplastics can transfer toxic additives and absorbed pollutants to organisms that ingest them, with potential implications for seafood safety and ultimately human health.
Microplastics transferring from abiotic to biotic in aquatic ecosystem: A mini review
A review compiled field data from dozens of studies and found that microplastics are more abundant in aquatic sediments than in water or in mussels and fish, and that a meaningful correlation exists between sediment and mussel contamination. However, the pathway and extent of biomagnification through the food chain remains unclear, as consistent evidence is lacking. The authors call for more standardized methods so studies can be reliably compared — a significant gap given ongoing concerns about microplastics entering human diets through seafood.
Contaminated aquatic sediments
This 2019 review summarizes published research on contaminated aquatic sediments, covering monitoring methods, pollutant transport, and remediation strategies across multiple contaminant types including microplastics. Aquatic sediments are a major sink and reservoir for microplastics as well as the chemical pollutants they carry.
