“…As short-chain PFASs, PFHpA (mean concentration: 25.73 ng/g•dw) and PFBA (mean concentration: 6.91 ng/g•dw) had a high detection ratio (100%) and concentration in all tadpole tissues. The current research is not in accordance with previous studies in that PFHxA was the predominant contaminant (80.50 ± 58.31 ng/g and 19.17 ± 12.57 ng/g ww), followed by PFOS (55.02 ± 34.82 and 14.79 ± 6.24 ng/g ww) in both fish from Lake Chaohu, China (Wu et al, 2019).…”

“…The concentrations of PFASs in the digestive system (intestines and stomach) were 52%, 45%, 65%, and 52% in adult bullfrog, young bullfrog, juvenile bullfrog, and tadpole, respectively, closely associated with ingesting contaminated bait. It was consistent with other studies in that the highest level in the digestive system among the different tissues was observed in carp and green eel goby, suggesting that PFASs can accumulate by diet from water, sediment, and contaminated bait intake (Hong et al, 2015;Wu et al, 2019). Moreover, liver, as a vital organ for fat metabolism and protein synthesis, also had a higher concentration level of PFASs than muscle.…”

“…The results suggest that frequent consumption of these bullfrogs would not cause severe health effects on residents. Similar results were reported in other studies (Wu et al, 2019;Sun et al, 2021). However, besides the bullfrog, other food species also pose risks for human exposure, which may increase the potential risks for local residents.…”

“…Moreover, liver, as a vital organ for fat metabolism and protein synthesis, also had a higher concentration level of PFASs than muscle. The possible reason for this is that liver could affect the binding of lipid and protein, and the protein content was generally at a higher level in liver while it was at a lower level in muscle (Chevreuil, 2010;Wen et al, 2019;Wu et al, 2019).…”

Per- and polyfluoroalkyl substances (PFASs) have captured worldwide attention due to their persistent and bioaccumulative characteristics. The bullfrog is a highly nutritious and edible aquatic product, but the PFAS accumulation characteristics of bullfrogs had not been paid attention. The present study analyzed the PFAS concentrations in different tissues of cultured bullfrogs and relevant water and sediments collected from the aquaculture region in the coastal area of South China. Results showed that total PFAS concentrations were 50.26–364.25 ng/L in water, with a mean of 135.58 ng/L; concentrations in effluent water were significantly higher than those in influent water, which means bullfrog farming could increase contaminants into the surroundings. The total PFAS concentrations varied from 2.89 to 162.26 ng/g·dw in sediment. The distribution profile of PFASs in sediment was similar to that of water, with short chain playing a significant role. Total PFASs in bullfrog tissues were 3.36–84.07 ng/g·dw, with the highest values in the digestive system (intestines and stomach). As for one novel PFAS alternative, chlorinated polyfluorinated ether sulfonate (F-53B) was found at high detectable levels in all habitat samples and had a higher value of logarithmic bioaccumulation factors. The estimated dietary intake (EDI) for residents in the study area was generally higher than that in other regions; however, the hazard ratios (HRs) for most detected PFASs were far below the safety threshold value “1.” These results suggest that frequent consumption of these bullfrogs would basically not cause severe health effects on local residents in terms of PFASs.

“…However, due to rapid development of industrialization and urbanization in recent decades, large amounts of industrial wastewater and domestic sewage have been discharged into the lake that aggravating water quality deterioration (Liu et al, 2012a). The lake has been stressed by harmful contaminants such as POPs (Lyu et al, 2021;Tang et al, 2019;Wu et al, 2019) and heavy metals (Fang et al, 2017(Fang et al, , 2019aZhang et al, 2019). Potential threat has been posed on the ecosystems including biota and ora even the health of residents (Fang et al, 2017(Fang et al, , 2019a.…”

Obtaining beneficial nutrients meanwhile ingesting hazardous contaminants through freshwater fish consumption remains a concern for inland residents in China. In this study, contents of fatty acids, essential trace elements (Fe, I, Zn, Se, Cu, Mo, Cr) and non-essential trace elements (As, Cd, Hg, Ni, Pb) were quantified in nine fish and two shrimp species from large eutrophic Chaohu Lake, southeastern China. Benefit-risk assessment for fish and shrimp consumption was conducted on basis of nutrients and contaminants. Total fat acids in the samples were 104.2-2405.2 mg/100g, included which DHA+EPA were 29.0-238.6 mg/100g. Mean content of essential trace elements (μg/g) in fish and shrimp species followed the order of Fe (10.3)>Cu (9.9)>Zn (7.7)> >Cr (1.42)>Se (0.337)>Mo (0.285)>I (0.023). The As, Cd, Hg, Ni, Pb content in the samples were nd-218, 14-97, 3-47, 4200-11300 and 144-1127 μg/kg, respectively, which was below the national maximum limit with the exception of Pb content in several samples. Though no obvious bioaccumulation pattern was found among species, species living in the demersal layers or with higher trophic levels tend to accumulate more trace elements. To achieve the recommended 250 mg of DHA+EPA daily intake, results of benefit-risk assessment indicated that fish and shrimp consumption can be major source of Se, Cu, Mo and Cr intake, whereas fish consumption was potential non-carcinogenic risk exposure for Ni and microcystins. Benefit-risk assessment contributed to the identification of main benefits and hazards of freshwater fish and shrimp consumption for inland populations around the large eutrophic lake.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are of increased concern because of their bioaccumulation in humans and the biota, the health risk they pose to humans and other animals, and their persistence in the environment. In the present study, the occurrence of PFAS in selected tissues from pike (Esox lucius L.) and roach (Rutilus rutilus L.) collected from two lakes in the Masurian Lake District (Poland) in eastern Europe was addressed. Ten PFAS were analyzed in the tissue of the brain, liver, kidneys, gonads, and muscles by micro-high-performance liquid chromatography coupled with tandem mass spectrometry. Only perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid, and perfluorodecanoic acid were detected above the limit of quantification. Concentrations in pike and roach from Ełckie Lake and Han ´cza Lake were estimated to be 14/27 and 4.4/3.2 ng/g wet weight, respectively. The contributions of PFOS and PFOA to the sum of PFAS calculated for particular tissues for each fish species were higher than those of the other analyzed compounds: PFOS was found to be predominant in fish from Ełckie Lake, whereas PFOA predominated in fish from Han ´cza Lake. It was noted that PFAS concentrations in tissues declined in the following order: kidney > gonads ≈ brain > liver > muscle. The sum of the greatest estimated PFAS concentration was 9.7 ng/g wet weight in kidneys of pike collected from Han ´cza Lake. No correlation was noted between PFAS concentration and fish size. The information provided in our study gives a better understanding of the potential dependencies in PFAS distribution and accumulation in biota.
