Implications for food safety of the uptake by tomato of 25 trace-elements from a phosphogypsum amended soil from SW Spain.

•Uptake of 25 trace-elements by tomato was studied in phosphogypsum-amended soils.•Cadmium had high transfer factors in tomato shoots (4.0) and fruits (1.5).•These two TF values of Cd increased to 5.7 and 2.5 after PG-inputs, respectively.•PG decreased the concentration of B, Cu, Sb, Cs, Ba, Tl and Th in fruits.•Assessment on trace elements in PG is needed to avoid exceeding legal limits in food.
