Soil available-iron (Fe) is crucial for various physiological properties and processes in plants, particularly those related to the accumulation translocation of per- polyfluoroalkyl substances (PFAS). However, mechanisms underlying impact available-Fe levels on PFAS plants remain unclear. In this study, we investigated impacts an emerging PFAS, 6:2 chlorinated ether sulfonate (6:2 Cl-PFESA), soybean, a typical dicot, through hydroponic experiments. Interestingly, Fe deficiency significantly enhanced soybean root volume, surface area, tip count, lipid content, thus favoring Cl-PFESA adsorption epidermis. its absorption aboveground tissues were markedly suppressed due reduced transpiration rate soluble protein content induced by deficiency. Conversely, although excessive also inhibited transpiration, it notably increased membrane permeability tissues, greatly facilitating within soybeans. These findings demonstrate that appropriate application agricultural soils essential promote growth dicot crops mitigate potential ecological risks associated with
