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


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

PEHSU are academically based, typically at university medical centers, and are located across the United States, Canada and Mexico. 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 children’s environmental health covers a wide variety of issues, the PEHSU network has experts in pediatrics, allergy/immunology, neurodevelopment, toxicology, occupational and environmental medicine, nursing, and other specialized areas.

See printable information sheet "What is the PEHSU Program?" (March 2013)

The presentation, "PEHSU Program Overview December 2011", provides the PEHSU Program objective, mission and history. It also provides an overview of the PEHSU site structure, staffing and services provided.


PEHSU work with health care professionals, parents, schools and community groups, and others to provide information on protecting children 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:

  • 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
