EPA 7196A PDF

The intent is not to provide an exhaustive list, but to identify well-established methods that are used as standards for analysis, particularly those used for environmental samples and approved by EPA and the National Institute for Occupational Safety and Health NIOSH. More innovative methods are also included if their components are commercially available. The ACGIH Standard is more complex; based upon epidemiological studies, it considers chromates confirmed human carcinogens. There are three different calculations depending upon the analytical method used. Boiano, Marjorie E.

Hexavalent chromium Cr VI occurrence in soils is generally determined using an extraction step to transfer it to the liquid phase where it is more easily detected and quantified.

Results obtained with both methods were compared for three solid samples with different matrices: a soil containing chromite ore processing residue COPR , a loamy soil, and a paint sludge. The underestimation is particularly pronounced for COPR.
