Table 3.

Distribution of Ti in roots and shoots of S. bicolor grown in Sb-contaminated soil, bioconcentration factors (BCF) and translocation factors (TF) in TiO₂ NPs, BC and TiO₂ NPs + BC treatments after 80 days. Standard deviations for three replicates are presented. Means that do not share a letter are significantly different at p = 0.05 (mean ± SD; n = 3).
