*2.5. Bioaccumulation and Translocation Factors*

Arsenic bioaccumulation factor (BAF) (i.e., the ability of a plant to accumulate this element from water) was calculated on a DW basis, as the ratio among its concentration in root (BAFroot), shoot (BAFshoot), and pulp (BAFpulp) and the corresponding concentration in the nutrient solution. The root-to-plant translocation factor (TF) defines the movement and distribution of As from roots to the aerial part of the plant. The TF was calculated on a DW basis, as the ratio between the As concentration in shoot (TFshoot) and fruit pulp (TFpulp), and the corresponding concentration in roots at the end of the experiment [26–28].
