Mineralogical and physicochemical methods to differentiate between natural and anthropogenic sources of chromium in soils

From: Water Environment Research | Date: September 1, 2000| Author: | Copyright information

ABSTRACT: This study evaluates pollution from a former tannery by examining soils containing high concentrations of chromium (between 138 and 720 mg/kg dry matter according to the sample). This study presents an original methodology for characterizing chromium according to its two possible origins in soils: natural or anthropogenic. Conducting both a mineralogical study and a physicochemical study made it possible to clearly understand these origins. Natural chromium is particularly linked to pyroxenes, a primary mineral of the Massif Central, France, and found in large quantities in the ...
