Three metallophyte species, Persicaria capitata, P. puncata (Polygonaceae), Conyza cordata (Asteraceae) from mineral wastes in the Zambian copper-cobalt belt were studied. This study focused on the elemental distribution in the roots, stems and leaves, using a range of techniques micro-PIXE, SEM-EDS synchrotron XFM and XAS. The species differed in their responses to growing on Co-Cu-enriched soils Persicaria puncata is a Co hyperaccumulator (up to 1060 μg g-1 in leaves), while Persicaria capitata and Conyza cordata are Co
