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 evaluation and treating of potentially exposed patients. This CSEM focuses on beryllium toxicity.

Available Versions

Two versions of the Beryllium Toxicity CSEM are available.


To make the most effective use of this course:

  • Take the Initial Check to assess your current knowledge about beryllium 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 wish to obtain continuing education credit. Continuing education certificates can be printed immediately upon completion.
