Webstable chromium hydroxide [Cr(OH)3J or chromium oxide [Crp3J or chromium oxide (Crp3) at pH> 5.5. Chromium hydroxide and Cr20 3 in soils are not readily absorbed by living organisms and are not transmitted in the food chain. However, Cr(Ill) treated with organic acids such as citric and fulvic acids remains soluble and WebMajor factors governing the toxicity of chromium compounds are oxidation state and solubility. Cr (VI) compounds, which are powerful oxidizing agents and thus tend to be irritating and corrosive, appear to be much more toxic systemically than Cr (III) compounds, given similar amounts and solubilities.
