A J Paine. 1. 2007;30(5):1092-1096.17303791. Of the two stable states that chromium exhibits, hexavalent chromium or Cr(VI) and trivalent chromium Cr(III), the former is more toxic and soluble. It happens when there’s friction between metal surfaces. Authors: Krishan, Prabha Publication Date: Tue Aug 31 00:00:00 EDT 1999 Research Org. 1267-1275. Chromium toxicity: Excessive consumption of chromium can cause symptoms of toxicity. The hexavalent chromium compounds appear to be 10–100 times more toxic than the trivalent chromium compounds when both are administered by the oral route. 21. The optimal treatment for chromium toxicity lies in its prevention, with the use of good industrial hygiene practices, of proper workplace industrial controls and good personal hygiene measures. Chronic exposure occurs over a number of years. Analysis of the morpho-functional trait dominance curves revealed low diversity into the highest Spirulina treatment (S3) compared to the chromium or chromium/Spirulina mixtures, supporting the stress-dependent patterns: M < MS < S. Numerous studies have shown that organic matter and trace metals interact in the substrate and that … References : 1 -Occupational Medicine,Carl Zenz, last edition.
