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 Principles of Pediatric Environmental Health and serves as a companion piece to the Pediatric Exposure History CSEM. This Case Study also serves to explicate further some of the background principles that form the bases for the pediatric environmental medicine practices found in the Pediatric Exposure History CSEM.


Two versions of the Principles of Pediatric Environmental Health CSEM are available.


To make the most effective use of this course.

  • Take the Initial Check to assess your current knowledge about principles of pediatric environmental health.
  • 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.

How does toxic exposure cause children’s disease?
  • Describe the exposure disease model.
What are common sources of toxicants to which children can be exposed?
  • Name common sources of toxic exposure to children.
What are factors affecting children’s susceptibility to toxicants?
  • Describe factors that usually render children more susceptible to exposure to toxicants compared to adults.
Why does a child’s age and developmental stage affect physiologic susceptibility to toxicants?
  • Identify reasons why children have unique and varying age-related susceptibilities to toxicants.
How can parents’ preconception exposures and in utero exposures affect a child?
  • Describe how exposures before conception can affect a child’s future development and health.
  • Identify how exposures of the fetus during pregnancy can affect a child’s future health.
How are newborns, infants and toddlers exposed to and affected by toxicants?
  • Describe the toxicant exposure routes most likely in early childhood.
What are special considerations regarding toxic exposures to young and school-age children and adolescents?
  • Describe where school-age children may be exposed.
  • Identify why adolescents face special risks from toxic exposures.

The Principles of Pediatric Environmental Health Case Study describes the basic science behind the newly emerging discipline of Pediatric Environmental Health. This publication serves as a companion document to the case study, “Taking a Pediatric Exposure History”.
