“…For example, PFOS accounted for 87.6% of the total PFCs in minnow eggs, whereas it only accounted for 42.6% of the total fluorinated compounds in white shrimp eggs [115]. The same also applies to phylogenetically close species, and for [PFAS] TOT , in a recent work, for example, considering the same marine area but different species (of mollusc) analysed, [PFAS] TOT showed the following trend: clams > mussels > scallops > peels > oysters [95].…”

“…As already mentioned, although there may be a different biodistribution of the different PFAS in the different tissues and species, one of the common factors that play an important role in biota contamination lies in the geographical origin, of the analysed organisms. It is known that PFAS contamination levels of organisms caught in waters affected by anthropogenic pollution are generally higher than concentrations in organisms from open oceans [93][94][95]. This correlation is highlighted in an important mollusc aquaculture area Bohai Sea (China) where PFAS contamination was verified in different species of molluscs sampled in the various mussel farming with higher levels of contamination in samples taken near industrial areas [95].…”

“…For instance, a study on molluscs from the semi-closed basin of the Bohai (China) and investigating the presence of 23 PFCs, showed differences between aquaculture sites and more restricted areas with PFOA being the more abundant component (87% of the total PFAS) showing a very high frequency of detection (i.e., percentage of samples where PFOA has been detected) of 98%, followed by PFNA, perfluorodecane sulfonic acid (PFDS) and PFOS [95]. Indeed, the most frequently detected PFCs in various tissues of aquatic organisms are long-chain PFAS such as PFOS [56,58,115,[117][118][119] and PFOA [78,83,95]. This frequency is particularly important when referred to organisms that are directly consumed by humans or by endangered species.…”

This review is a survey of recent advances in studies concerning the impact of poly- and perfluorinated organic compounds in aquatic organisms. After a brief introduction on poly- and perfluorinated compounds (PFCs) features, an overview of recent monitoring studies is reported illustrating ranges of recorded concentrations in water, sediments, and species. Besides presenting general concepts defining bioaccumulative potential and its indicators, the biodistribution of PFCs is described taking in consideration different tissues/organs of the investigated species as well as differences between studies in the wild or under controlled laboratory conditions. The potential use of species as bioindicators for biomonitoring studies are discussed and data are summarized in a table reporting the number of monitored PFCs and their total concentration as a function of investigated species. Moreover, biomolecular effects on taxonomically different species are illustrated. In the final paragraph, main findings have been summarized and possible solutions to environmental threats posed by PFCs in the aquatic environment are discussed.

“…Due to the strength and stability of the carbon–fluorine bond, PFAS are generally resistant to hydrolysis, photolysis, or microbial degradation, and are highly persistent in all environmental compartments, especially water 3 , 4 . PFAS have been also found in wildlife 5 , 6 fish and other seafood 7 – 9 and have a high affinity for sediments and organic matter due to chemical adsorption phenomena 10 , 11 . Additionally, PFAS can potentially interfere with normal reproductive and hormonal functions as endocrine disruptors, showing adverse effects, for example PFOA exposure is associated with kidney and testicular cancer in humans 12 .…”

“…In the majority of studies reporting PFAS contaminated matrices 8 , 9 , 13 perfluorooctanoic acid (PFOA) is among the most frequently detected compounds at concentration levels significantly higher than other minor fluorinated pollutants. Probably this situation will continue to be recorded despite PFOA (its salts and related-compounds) was added to Annex A of the Stockholm Convention in 2019 and its use has recently been limited by the European legislation 14 .…”

The first determination of presence and biodistribution of PFOA in ninety specimens of sea urchin Paracentrotus lividus from two differently contaminated sites along Palermo’s coastline (Sicily) is reported. Analyses were performed on the sea urchins’ coelomic fluids, coelomocytes, gonads or mixed organs, as well as on seawater and Posidonia oceanica leaves samples from the collection sites. PFOA concentration ranged between 1 and 13 ng/L in seawater and between 0 and 794 ng/g in P. oceanica. The analyses carried out on individuals of P. lividus from the least polluted site (A) showed PFOA median values equal to 0 in all the matrices (coelomic fluid, coelomocytes and gonads). Conversely, individuals collected from the most polluted site (B) showed median PFOA concentrations of 21 ng/g in coelomic fluid, 153 ng/g in coelomocytes, and 195 ng/g in gonads. Calculated bioconcentration factors of log10BCF > 3.7 confirmed the very bioaccumulative nature of PFOA. Significant correlations were found between the PFOA concentration of the coelomic fluid versus the total PFOA concentration of the entire sea urchin. PERMANOVA (p = 0.001) end Welch's t-test (p < 0.001) analyses showed a difference between specimens collected from the two sites highlighting the potential application of P. lividus as sentinel species for PFOA biomonitoring.

Per-and polyfluoroalkyl substances (PFAS) are a numerous class of chemical compounds characterized by a C-F backbone of variable length with either a sulfonic acid group (PFSA) or a carboxylic acid (PFCA), produced for more than 70 years at industrial level. 1 PFOS and PFOA are the predominantly cited molecules of this class. Currently, these compounds are debated both at scientific and political levels due to the risks associated to exposure to legacy (PFOA, PFOS, etc.) and to emerging perfluorinated compounds (HFPO-DA or GenX, ADONA, C 6 O 4 ), introduced after the banning in the production/ import/use of PFOA and PFOS. 2,3 Studies on the bioaccumulation factor (BAF) of PFAS-that is, the degree of accumulation of a contaminant in an organism relative to its environment-correlated the length of the carbon chain (C6 > PFSA and C8 > PFCA) to higher BAF potential. On this base, the class of emerging PFAS, characterized by a shorter C-F backbone, had been considered less hazardous. Recent findings, however, confirm a lower accumulation potential in biota for short chain PFAS but similar toxicological effects as long chain counterparts. 4,5 Moreover, analyses on surface and ground waters at PFAS production plants discovered the incidence of important quantities of PFOA and PFOS branched isomers. The amounts were closely associated with the chemical reaction adopted for the production (electrochemical fluorination vs. telomerization) at the site, which consist of 22-29% of the total amount produced. 6 In the environment, branched isomers have been reported to concentrate in higher amount in soil and sediments, with less tendency to leaching, 6,7 while at biological level, they displayed different partitioning, bioaccumulation, metabolism and toxicity in living organism. 8,9 At present, studies showed as
