How to Use This Course


The goal of Case Studies in Environmental Medicine (CSEM) is to increase the primary care provider’s knowledge of hazardous substances in the environment and to help in the evaluation and treatment of potentially exposed patients. This CSEM focuses on carbon tetrachloride toxicity.


Two versions of the carbon tetrachloride toxicity CSEM are available.

  • The HTML version  provides content through the Internet.
  • The downloadable PDF version provides content in an electronic, printable format, especially for those who might lack adequate Internet service.

The HTML version offers interactive exercises and prescriptive feedback to the user.


To make the most effective use of this course:

  • Take the Initial Check to assess your current knowledge about carbon tetrachloride toxicity.
  • Read the title, learning objectives, text, and key points in each section.
  • Complete the progress check exercises at the end of each section and check your answers.
  • Complete and submit your assessment and posttest response online if you want free continuing education credit. You can print your continuing education certificate immediately after course completion.
