Chromium levels in soil vary according to area and the degree of contamination from anthropogenic chromium sources. Tests on soils have shown chromium concentrations ranging from 1 to 1000 mgkg with an average concentration ranging from 14 to about 70 mgkg 4. ChromiumVI in soil can be rapidly reduced to chromiumIII by organic matter.
