Abstract
Reference materials for the speciation and quantification of chromium is contaminated soils were prepared by impregnating diatomaceous earth with BaCrO4 and Cr2O3. The chromium concentrations of these materials were confirmed to be 200 mg/kg both by atomic absorption spectrometry and by instrumental neutron activation analysis, but monthly assays o ver two calendar quarters of the reference material impregnated with B aCrO4 revealed the hexavalent chromium was not stable in this matrix.
