“…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.…”

“…48 However, other studies showed that the hydrophobicity existed only in long-chain PFAAs. Wu et al 44 found that the removal rate of short chain PFAAs did not meet the chain length limitation. Li et al 38 found that the surface biofilm of submerged plants only had a significant chain length limit of long-chain PFAAs (C8−C12), while short chain PFAAs (C4−C7) tended to be adsorbed in the biofilm EPS.…”

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.
