A network of experts in reproductive and children’s environmental health

About the PEHSU Program

What are Pediatric Environmental Health Specialty Units (PEHSUs)?

The Pediatric Environmental Health Specialty Units (PEHSUs) are a source of medical information and advice on environmental conditions that influence reproductive and children’s health.

PEHSUs are academically based, typically at university medical centers, and are located across the United States and Canada. These PEHSU form a network that is capable of responding to requests for information throughout North America and offering advice on prevention, diagnosis, management, and treatment of environmentally-related health effects in children.

Because environmental factors have a variety of impacts on the health of children and reproductive age adults, the PEHSU network has experts in pediatrics, allergy/immunology, neurodevelopment, toxicology, occupational and environmental medicine, nursing, reproductive health and other specialized areas.

What PEHSUs Do

PEHSU work with health care professionals, parents, schools and community groups, and others to provide information on protecting children and reproductive-age adults from environmental hazards. They also work with Federal, State, and local agencies to address children’s environmental health issues in homes, schools, and communities. The basic services of the PEHSU network are: 

Community Education and Outreach

  • Raising awareness about environmental conditions that may harm children and families
  • Guidance on preventing or reducing harmful environmental exposures in everyday situations
  • Providing practical advice on helping children cope and recover during and after floods, wildfires, chemical spills and other crises

Training Health Professionals

  • Conducting seminars and conferences
  • Publishing peer-reviewed articles that raise environmental health literacy
  • Translating health care research into medical practice
  • Providing on-line educational programs and case studies on environmental health issues

Consultation and Referral

  • Evaluating suspected toxic exposures
  • Identifying and interpreting appropriate diagnostic tests
  • Medical management
  • Referral to specialty care
