Table 1.

Bulk concentrations, contents and the section-specific concentrations of the elements in whole grain of wheat grown in non-fertilized and Zn-fertilized soil. Data are means ± standard errors. Bulk concentrations were measured with ICP-MS and ICP-OES; n = 4. Total element content was calculated by multiplying bulk element concentration with grain yield. Section-specific concentrations were calculated from numerical matrices generated by GeoPIXEII software from micro-PIXE scans at each grain cross section using the ImageJ program [22]; n = 3. LOD, below the limit of detection.
