Description:

Thallium (TI) is an extremely toxic metal which, due to its similarities to K, is readily taken up by plants. Thallium is efficiently hyperaccumulated in Iberis intermedia as TI(I). Distribution and compartmentalization of TI in I. intermedia is highest within the vascular network of leaves as determined by synchrotron X-ray differential absorption-edge computed microtomography (CMT). Analysis of fresh leaves and sample preparation involving immersion in liquid nitrogen followed directly by freeze drying yielded similar results. CMT shows great promise for application in a wide variety of metal-related structural issues due to its high 3D resolution and being a non-destructive analysis tool.
