The present study explored the potential of phytoremediaion
of co-contamination of HMs and B[a]P with T. patula. The growth
of the plants could be enhanced compared with the control when
B[a]P treated soils was ≤10mgkg−1, the concentrations of B[a]P
in all parts of the plants were elevated with the increase of soil
B[a]P concentrations, but the concentrations of B[a]P in shoots were
lower than those in roots and the BFs and TFs of B[a]P were lower
than 1.0. Under co-contamination of metal–B[a]P treatments, the
addition of HMs could affect the plant growth and B[a]P uptake
and accumulation. T. patula can hyperaccumulate Cd from combined
contaminated soils, whereas for Cu and Pb absorption with
