Abstract
Abstract The results of an interlaboratory study, with 45 participants, of the analysis of Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, Tl, and F in soil samples by specified extraction techniques and optional measurement procedures are presented. The results are presented graphically as the relationship between robust coefficients of variation of reproducibility and the robust mean concentrations, separately for individual analytical measurement procedures. The graphs clearly show the strongly differing degree of comparability for the various elements and extraction techniques over the range of respective concentrations. The often considerable influence of the analytical measurement procedure on the comparability of the laboratory results also becomes apparent.
