Analytical Methods Total Chromium (see Part V, Chapter 2) 

The determination of total chromium at relatively high concentrations is not difficult. Methods include atomic absorption with flame (EAAS) or graphite furnace 

Chromium at the low levels seen in these tissues can also be determined by stable isotope dilution and mass spectrometry, by AES, and by NAA. 

Analytical Methods Chromium Speciation (see Party, Chapter 3) 

Because hexavalent chromium is the toxic form of the metal, a number of researchers have focused on methods for distinguishing between chromium(III) and chromium(VI). Analytical techniques for chromium speciation in liquid matrices were reviewed recently (Marques etal. 2000). There are concerns about chromium as a drinking water contaminant in some areas, and samples most frequently analyzed were standard waters, potable waters and wastewaters.
