“Comparing bioconcentration factor between plant species and components
Besides uptake of an element, which tissue and location the plant moves the element to (i.e., translocation) is an important part of how the plant removes the element from the soil. Differences in elemental levels between different plant components are reported in Fig. 5. On average, the reported numbers for BCF values were higher in the roots compared to the leaf and stem (p < 0.05; Fig. 5 and data repositary25). These results suggest that movement from the roots to the stems and leaves is a significant impediment to concentrating the element in the above-ground biomass. Sunflower was the only plant that had a median BCF value for leaf samples as high as the median BCF for the roots, making this plant the best suited for phytoextraction30,31,32. This explains the popularity of using sunflower in bioremediation experiments.”
