“…However, agricultural nonpoint source pollution in the eastern area might have contributed more to PFAS contamination in the rivers. The total contribution of livestock farming, poultry breeding, and rural household waste among the sources of agricultural nonpoint source pollution is up to more than 80% of organic pollutants. , Therefore, the high concentrations of PFAS caused by agricultural nonpoint source pollution deserve attention.…”

Amphibians are sensitive biomonitors of environmental pollutants but reports regarding per-and polyfluoroalkyl substances (PFAS), a class of synthetic organofluorine substances, are limited. In this study, samples of water and Chinese toads (Bufo gargarizo) were collected in Chaohu Lake, China. Tissue-specific bioaccumulation characteristics of 39 PFAS, including 19 perfluoroalkyl acids (PFAAs), 8 emerging PFAS, and 12 PFAA precursors, were investigated, and the levels of some biochemical indicators were determined. The highest PFAS concentrations were found in the liver [215.97 ng/g dry weight (dw)] of Chinese toads, followed by gonads (135.42 ng/g dw) and intestine (114.08 ng/g dw). A similar tissue distribution profile was found between legacy and emerging PFAS in the toads, and the occurrence of two emerging PFAS, 2,3,3,3-tetrafluoro-2-propanoate (HFPO-DA) and 6:2 hydrogen-substituted polyfluorooctane ether sulfonate (6:2 H-PFESA) in the amphibians were for the first time reported. Fieldbased bioaccumulation factors of HFPO-DA were higher than perfluorooctanoic acid, indicating the higher bioaccumulation potential of this emerging PFAS than the legacy C8 compound. Males had significantly higher gonad PFAS levels than females while estradiol levels in gonads increased with increasing concentrations of certain PFAS (e.g., 6:2 H-PFESA), implying that PFAS may trigger estrogenic effects in the toads, especially for male toads.

“…In aquatic environments, PFAAs with shorter chain length tend to enrich in water. , In solid media, such as the surface of soil particles, sediment, aquatic suspended particles and the tissues of aquatic organisms, , PFAAs’ translocation factor (TF) is also positively correlated with the chain length, which is often due to the hydrophobicity of PFAAs . However, other studies showed that the hydrophobicity existed only in long-chain PFAAs.…”

“…PFAAs' concentrations were slightly higher than the previous studies to ease detection of PFAA accumulation. 5,37 In sum, 15 polypropylene plastic (PP) pots (diameter = 15 cm, height = 10 cm) were used for wheat growth and filled with approximately 500 g of PFAAs-treated soil, and 3 wheat plants were put into each experimental pot. Simultaneously, 500 mL of Milli-Q water was added into the soil of each pot.…”

“…3 As a result, PFAAs' maximum concentrations in farmland soil have been observed at hundreds of milligrams per kilogram of soil. 4 PFAAs will absorb on the surface of soil particles and dissolve into the soil solution, 5 significantly endangering the growth of crops. 6 Illuminating the adsorption−desorption cycle as it relates to biological enrichment from PFAAs improves the ecological evaluation of crops.…”

Understanding the mechanisms underlying perfluoroalkyl acids (PFAAs) translocation, distribution, and accumulation in wheat–soil ecosystems is essential for agricultural soil pollution control and crop ecological risk assessment. This study systematically investigated the translocation of 13 PFAAs under different iron and nitrogen fertilization conditions in a wheat–soil ecosystem. Short-chain PFAAs including PFBA, PFPeA, PFHxA, and PFBS mostly accumulated in soil solution (10.43–55.33%) and soluble extracellular polymeric substances (S-EPS) (11.39–14.77%) by the adsorption to amino- (−NH2) and hydroxyl (−OH) groups in dissolved organic matter (DOM). Other PFAAs with longer carbon chain lengths were mostly distributed on the soil particle surface by hydrophobic actions (74.63–94.24%). Iron–nitrogen amendments triggered (p < 0.05) soil iron–nitrogen cycling, rhizospheric reactive oxygen species fluctuations, and the concentration increases of −NH2 and −OH in the DOM structure. Thus, the accumulation capacity of PFAAs in soil solution and root EPS was increased. In sum, PFAAs’ translocation from soil particles to wheat root was synergistically reduced by iron and nitrogen fertilization through increased adsorption of soil particles (p < 0.05) and the retention of soil solution and root EPSs. This study highlights the potential of iron–nitrogen amendments in decreasing the crop ecological risks to PFAAs’ pollution.
