Breathing in high levels of hexavalent chromium can cause irritation to the nose and throat. Symptoms may include runny nose, sneezing, coughing, itching and a burning sensation. Repeated or prolonged exposure can cause sores to develop in the nose and result in nosebleeds.
What causes chromium toxicity?
Major 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.
What can chromium hexavalent cause?
Hexavalent chromium can irritate the nose, throat, and lungs. Repeated or prolonged exposure can damage the mucous membranes of the nasal passages and result in ulcers. In severe cases, exposure causes perforation of the septum (the wall separating the nasal passages).

Which form of chromium is toxic?
Trivalent chromium, or chromium(III), is the form of chromium that is essential to human health. Hexavalent chromium, or chromium(VI), is an unequivocally toxic form.
How bad is hexavalent chromium?
Hexavalent chromium is harmful to the eyes, skin, and respiratory system. NIOSH considers all Cr(VI) compounds to be occupational carcinogens. Workers may be harmed from exposure to hexavalent chromium. The level of exposure depends upon the dose, duration, and work being done.
Is hexavalent chromium banned in the US?
OSHA has no authority to ban use of hexavalent chromium.
Is chromium a hazardous waste?
Chromium-containing waste with a TCLP greater than or equal to 5 ppm or mg/L carries a D007 hazardous waste code. Waste that contains Cr(III) only is considered nonhazardous. Other chromium-containing wastes are “listed” hazardous wastes; these wastes are generated by certain processes, including metal plating.
