2000-8-1 · In A. ageratum, the distribution and accumulation of antimony in the plant parts, as well as the translocation of the element from the roots to the epigeal parts, are not homogeneous (Table 2, Table 3, Table 4).Sometimes the roots are the target part, with a high concentration coefficient (as at MD 2), but more often the species accumulates Sb in the basal leaves and inflorescences (when present).
