Effects of the application of an organic amendment and nanoscale zero-valent iron particles on soil Cr(VI) remediation

Chromium is considered an environmental pollutant of much concern whose toxicity depends, to a great extent, on its valence state, with Cr(VI) being more soluble, bioavailable, and toxic, compared to Cr(III). ...
