Description
Summary:The development and certification of a new Great Lakes sediment reference material is described. The new matrix, analytes and concentrations differ from, but complement, those previously reported, thus enhancing diversity of our quality control samples and effectiveness of the overall quality assurance program at NWRI. Using a multi-laboratory and multi-methodology approach, the certified values for total metals (μg g −1 except for Fe in %) were derived to be: 1264 ± 91 Mn, 6.0 ± 0.4 Fe, 15.3 ± 1.7 Co, 52.0 ± 6.1 Ni, 1396 ± 107 Zn, 18.8 ± 1.5 As, 1.15 ± 0.19 Se, and 2.75 ± 0.28 Hg.
