a

Mean value ± standard deviation, n = 3.

b

Non-detectable.

c

4′-PCB 3 sulfate in shoots and leaves and bark samples were not analyzed in this work due to the matrixes in these samples containing pigments which can greatly influence the extraction and detection of 4′-PCB 3 sulfate (Zhai et al., 2013).
