英文摘要	The interaction between arsenic (As) and phenanthrene (PHE) in Pteris vittata L. was investigated in this study. The migration and occurrence of PHE in P. vittata were determined by two-photon laser scanning confocal microscopy. Data indicated that PHE supplementation lowers the As concentration in P. vittata, decreasing As levels by 16.8-39.9% in the pinnae, 30.0-49.0% in the rachis, and 45-51.5% in the roots, respectively. Different arsenic species inhibited P. vittata PHE absorption. The most significant effect was observed using dimethylarsenic acid (DMA), which decreased PHE accumulation by 20.73%. With the exception of elevated As(V) concentrations in As(III)-treated plants, PHE treatment significantly reduced inorganic As concentrations in P. vittata. However, PHE elevated root DMA concentrations by 9%. According to in situ visualization, PHE is primarily found in the upper and lower epidermis and stomatal cells, particularly the stomata guard cells. (C) 2016 Elsevier Ltd. All rights reserved.
