Summary of "Bisphenol A and its analogs in muscle and liver of fish from the North East Atlantic Ocean in relation to microplastic contamination. Exposure and risk to human consumers."

In the present study, the levels of bisphenol A (BPA) and analagous compounds in muscle and liver of fish (Dicentrarchus labrax, Trachurus trachurus, Scomber colias) from the North East Atlantic Ocean were determined and the risk of their consumption by humans was assessed. The potential relationship between bisphenol concentrations and microplastic (MP) contamination of fish was also investigated. Fish from all the species had BPA in the liver and muscle, and bisphenol B (BPB) and bisphenol E (BPE) in the muscle. The highest concentration of BPA in the liver (302 ng/g dry weight - dw) was found in S. colias and the lowest one (5 ng/g dw) in T. trachurus. In the muscle, the bisphenol with the highest concentration was BPE in S. colias (272 ng/g dw). Fish with microplastics had significantly higher concentrations of bisphenols than fish where no microplastics were found, suggesting a relation between MP and bisphenol contamination in fish. In all species, the concentration of bisphenols was correlated with higher MP intake. Regarding human food safety, the estimated daily intake (EDI), target hazard quotient (THQ) and hazard index (HI) of bisphenols were higher than those established by the European Food Safety Authority suggesting hazardous risk for human consumers. These findings highlight the need of more research on fish contamination by MP and associated chemicals and inherent human food safety risks.

Medical and Biotech [MESH] Definitions

Fish of the genera ONCORHYNCHUS and Salmo in the family SALMONIDAE. They are anadromous game fish, frequenting the coastal waters of both the North Atlantic and Pacific. They are known for their gameness as a sport fish and for the quality of their flesh as a table fish. (Webster, 3d ed).

The reaction product of bisphenol A and glycidyl methacrylate that undergoes polymerization when exposed to ultraviolet light or mixed with a catalyst. It is used as a bond implant material and as the resin component of dental sealants and composite restorative materials.

Oils high in unsaturated fats extracted from the bodies of fish or fish parts, especially the livers. Those from the liver are usually high in vitamin A. The oils are used as dietary supplements, in soaps and detergents, as protective coatings, and as a base for other food products such as vegetable shortenings.
