[[Hexavalent chromium]] compounds can be [[toxic]] and [[carcinogenic]] ([[IARC Group 1]]). Inhaling particles of hexavalent chromium compounds can cause [[lung cancer]]. Also positive associations have been observed between exposure to [[chromium (VI)]] compounds and [[cancer]] of the [[nose]] and [[nasal sinuses]].<ref name=book100C>{{cite book

 |quote = There is ''sufficient evidence'' in humans for the [[carcinogenicity]] of chromium (VI) compounds. Chromium (VI) compounds cause cancer of the lung. Also positive associations have been observed between exposure to chromium (VI) compounds and cancer of the nose and nasal sinuses. There is ''sufficient evidence'' in experimental animals for the carcinogenicity of chromium (VI) compounds. Chromium (VI) compounds are ''carcinogenic to humans (Group 1)''.
