How toxic is dichromate?
How toxic is dichromate?
Acute dichromate toxicity is a rare and usually fatal event. The estimated lethal dose of the toxin is 0.1–1 g. Dichromic acid is a hexavalent compound, and the toxicity is attributed to its oxidizing effect. The hexavalent ion is freely taken up by red blood cells and platelets.
Why is it important to be careful with the chromate solution you will be using in today’s experiment?
► Potassium Chromate is a CARCINOGEN in humans. There may be no safe level of exposure to a carcinogen, so all contact should be reduced to the lowest possible level. contact also occurs you may be overexposed, even though air levels are less than the limits listed above.
