This case study is available in English, and is intended for advanced level health care providers with the goal of increasing the provider’s knowledge of hazardous substances in the environment and to aid in the evaluation of potentially exposed patients. This case study provides information related to at risk populations, exposure pathways, physiologic effects, clinical evaluation, treatment and management, as well as workplace and environmental standards and regulations of chromium toxicity. Upon completion of this case study the participant should be able to discuss the major exposure route for chromium, describe two potential environmental and occupational sources of exposure to chromium, state two reasons why chromium is a health hazard, describe three factors contributing to chromium toxicity, identify evaluation and treatment protocols for persons exposed to chromium, and list sources of information on chromium.
