Chromium in the environment: factors affecting biological remediation
@article{Zayed2004ChromiumIT, title={Chromium in the environment: factors affecting biological remediation}, author={Adel M. Zayed and Norman Terry}, journal={Plant and Soil}, year={2004}, volume={249}, pages={139-156} }
Chromium, in the trivalent form (Cr(III)), is an important component of a balanced human and animal diet and its deficiency causes disturbance to the glucose and lipids metabolism in humans and animals. In contrast, hexavalent Cr (Cr(VI)) is highly toxic carcinogen and may cause death to animals and humans if ingested in large doses. Recently, concern about Cr as an environmental pollutant has been escalating due to its build up to toxic levels in the environment as a result of various…

Significant differences are demonstrated among Cr-contaminated soils in their capacity to release Cr(VI) upon chemical treatment with H2O2, which could be a hazardous consequence of using H1O2 for in situ remediation of chemically complex wastes, but could prove attractive for ex situ treatment (i.e., soil washing).
