Assessment of metal accumulation capacity of Dittrichia viscosa (L.) Greuter in two different Italian mine areas for contaminated soils remediation

Regarding the leaf/root ratio, this species also displayed a greater capacity, in sub alkaline mine areas, to shift PHEs from roots to aboveground tissues, along with Ca transfer, revealing interesting characteristics for phytoextraction. In sub acid mine areas, this tendency was instead weaker and PHEs tended to be accumulated in all plant parts. Dittrichia viscosa seems to be appropriate for mine soil stabilization in both sub acid and sub alkaline environments and also for phytoextraction in the latter.
