“…This indicates that PFAS bioaccumulation in European chub was not sex-dependent for the life stages considered in our study (i.e. mostly immature individuals), as observed elsewhere (Gewurtz et al, 2012;Pan et al, 2014;Arinaitwe et al, 2020;Schultes et al, 2020). Here, fish length influence was not significant, while it was an important driver of PFAS bioaccumulation in the cyprinid Barbus barbus from the Rhône River (Babut et al, 2017) or in the common sole Solea solea from the Gironde estuary (Munoz et al, 2017a).…”

“…PFAS are a chemical family of compounds that have been produced since late 1940s [30]. They are found nowadays worldwide; they have been detected in oceans, across continents and in remote parts of the globe [31] including the North and South Pole [32][33][34][35][36][37][38], with several ecosystems affected in the USA, China, Africa, and Europe [39][40][41][42][43][44][45][46][47]. Their presence has been recorded in several different matrices, from the aquatic system to flora and fauna [48].…”

Due to their unique properties, perfluorinated substances (PFAS) are widely used in multiple industrial and commercial applications, but they are toxic for animals, humans included. This review presents some available data on the PFAS environmental distribution in the world, and in particular in Europe and in the Veneto region of Italy, where it has become a serious problem for human health. The consumption of contaminated food and drinking water is considered one of the major source of exposure for humans. Worldwide epidemiological studies report the negative effects that PFAS have on human health, due to environmental pollution, including infertility, steroid hormone perturbation, thyroid, liver and kidney disorders, and metabolic disfunctions. In vitro and in vivo researches correlated PFAS exposure to oxidative stress effects (in mammals as well as in other vertebrates of human interest), produced by a PFAS-induced increase of reactive oxygen species formation. The cellular antioxidant defense system is activated by PFAS, but it is only partially able to avoid the oxidative damage to biomolecules.

“…However, it is known that both N. tangkachkeii , L. niloticus and P. hypophthalmus come from highly polluted freshwater basins of extra-European countries that pay little attention and no control to the level of pollutant bioaccumulation in edible fish. In this context, classic and emerging contaminants of aquatic environment have been widely detected in fish living in Chinese lakes (Chaohu, Taihu) such as icefish N. tangkachkeii and N. taihuensis [ 67 , 68 ] and the biomagnification of polyfluoroalkyl substances, mercury, organochlorine pesticides in Nile Perch living in the open waters of African lakes, has been found to pose health risk to the consumers [ 69 , 70 , 71 , 72 ]. Furthermore, very recent investigations [ 73 , 74 ] documented high contamination of liver and muscle of P. hypophthalmus farmed in Asian Countries highlighting the severe threat for the human health.…”

The DNA analysis is the best approach to authenticate species in seafood products and to unveil frauds based on species substitution. In this study, a molecular strategy coupling Cytochrome Oxidase I (COI) DNA barcoding with the consolidated methodology of Restriction Fragment Length Polymorphisms (RFLPs), named COIBar-RFLP, was applied for searching pattern of restriction enzyme digestion, useful to discriminate seven different fish species (juveniles of Engraulis encrasicolus and Sardina pilchardus sold in Italy as “bianchetto” and Aphia minuta sold as “rossetto”; icefish Neosalanx tangkahkeii; European perch, Perca fluviatilis and the Nile Perch, Lates niloticus; striped catfish, Pangasianodon hypophthalmus). A total of 30 fresh and frozen samples were processed for DNA barcoding, analyzed against a barcode library of COI sequences retrieved from GenBank, and validated for COIBar–RFLP analysis. Cases of misdescription were detected: 3 samples labeled as “bianchetto” were substituted by N. tangkahkeii (2 samples) and A. minuta (1 sample); 3 samples labeled as “persico reale” (P. fluviatilis) were substituted by L. niloticus and P. hypophthalmus. All species were simultaneously discriminated through the restriction pattern obtained with MspI enzyme. The results highlighted that the COIBar-RFLP could be an effective tool to authenticate fish in seafood products by responding to the emerging interest in molecular identification technologies.
