英文摘要: The roles of protein and lipid in the accumulation and distribution of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in seven species of plants from biosolids-amended soils were investigated. The PFOS and PFOA root concentration factors (C-root/C-soil) ranged from 1.37 to 4.68 and 1.69 to 10.3 (ng/g(root))/(ng/g(soil)), respectively, while the translocation factors (C-shoot/C-root) ranged from 0.055 to 0.16 and 0.093 to 1.8 (ng/g(shoot))/(ng/g(root)), respectively. The PFOS and PFOA accumulations in roots correlated positively with root protein contents (P < 0.05), while negatively with root lipid contents (P < 0.05). These suggested the promotion effects of protein and inhibition effects of lipid on root uptake. The translocation factors correlated positively with the ratios between protein contents in shoots to those in roots (P < 0.05), showing the importance of protein on PFOS and PFOA translocation. This study is the first to reveal the different roles of protein and lipid in the accumulation and distribution of PFOS and PFOA in plants. (C) 2016 Elsevier Ltd. All rights reserved.
