Welcome to the Pediatric Environmental Health Specialty Unit (PEHSU) at the University of California, Irvine. The Pediatric Environmental Health Specialty Units (PEHSU) are a network of experts in children's environmental health located throughout North America. The units were created to ensure that children and communities have access to specialized medical knowledge and resources for children faced with a health risk due to a natural or human-made environmental hazard.

PEHSU professionals provide quality medical consultation for health professionals, parents, caregivers, and patients. We are also dedicated to increasing knowledge of children's environmental health and environmental medicine among healthcare professionals by providing consultation and training. In addition, we provide information and resources to schools and community groups to help increase the public’s understanding of children's environmental health.
