Fig. 4 showed the fluorescence microscopy images and the
concentration of Antdistributed in the root tissues of K. obovata
seedlings. The concentrations of Ant entering root tissues decreased slightly to 1011ng/area under flooded condition.Similar
results were also observed for Nap and B[a]P. The concentration of
PAHs (Nap,Ant or B[a]P) determined by GC/MS method (Table S2)
was higher than the results of our established method
