LOD and LOQ for each analyte are shown in Table 4 alongside
typical sample concentrations. LOD and LOQ values were of a similar
magnitude to those previously reported (Cubadda et al., 2002;
Nardi et al., 2009). The analytical methods were sufficiently sensitive
to quantify all of the tested elements in peanut kernels,
excluding Cr, Na, and Se, which were present at levels lower than
the LOD in some samples
