(Left) Grapes with a green rectangle indicating the (center) detail area where (right) the elemental distribution maps for chromium (Cr-Kα) and potassium (K-Kα) were acquired by XRF scanning.

The zinc (Zn) map is not shown here for clarity and can be found in Additional file 1: Fig. S2. Image rights for Grapes:
