Key Concepts

  • Because of combustion of fossil fuels and organic waste, PAHs are ubiquitous in the environment
  • Studies show that certain PAH metabolites interact with DNA and are genotoxic, causing malignancies and heritable genetic damage in humans.
  • In humans, heavy occupational exposure to mixtures of PAHs entails a substantial risk of lung, skin, or bladder cancer.

About This and Other Case Studies in Environmental Medicine

This educational case study document is one in a series of self-instructional modules designed to increase the primary care provider’s knowledge of hazardous substances in the environment and to promote the adoption of medical practices that aid in the evaluation and care of potentially exposed patients. The complete series of Case Studies in Environmental Medicine is located on the ATSDR Web site at http://www.atsdr.cdc.gov/csem/csem.html. In addition, the downloadable PDF [546 KB] version of this educational series and other environmental medicine materials provides content in an electronic, printable format, especially for those who may lack adequate Internet service.
