Jiangsu High-Tech Fluorochemical Industrial Park in Changshu City, Province, is the largest fluorochemical industrial park Asia. The occurrence of per- and polyfluoroalkyl substances (PFASs) surface water widespread local plants was investigated Park. Thirty-two target PFASs were detected dissolved-phase, particle-phase plant samples. concentrations total ranged from 1650 to 8250 ng/L dissolved-phase samples, 132 6810 ng/g dw samples 25.8 9460 different tissues. Perfluorohexanoic acid (PFHxA), Perfluorooctanoate (PFOA) 6:2 fluorotelomer carboxylic (6:2 FTCA) predominant contributed 80−91% ΣPFAS A 67 emerging PFAS identified all using nontargeted analysis. Typha orientalis showed better accumulation ability, with an average concentration 3450 highest root factor (RCF) 171. orientalis, Eichhornia crassipes Alternanthera sessilis have potential for use phytostabilization.

Despite the widespread presence of per- and polyfluoroalkyl substances (PFAS) in freshwater environments, only a few studies have addressed their bioaccumulation macrophytes benthic invertebrates. This study therefore aimed at investigating 40 PFAS sediments, assessing rooting macrophyte (Myriophyllum spicatum) invertebrate (Lumbriculus variegatus) examining effects bioturbation activity on plants. The were exposed to sediments originating from reference PFAS-contaminated site. worms introduced half replicates, end experiment, quantified all environmental compartments. Numerous targeted detected both taken up by organisms, with summed concentrations organisms largely exceeding original sediments. Bioaccumulation differed between two significantly reduced plant tissues, but for some compounds, root increased worms. effect was most prominent degradable precursors. It is concluded that affect fate PFAS, emphasizing contaminant–macroinvertebrate interactions are two-sided.
