Pediatrics Environmental Health Specialty Units logo

Children's Mercy provides comprehensive pediatric environmental health services through the Mid-America Pediatric Environmental Health Specialty Unit (MAPEHSU). It is one of 13 Pediatric Environmental Health Specialty Units (PEHSUs) located in the continental United States and in Canada and Mexico. The program works to expand the knowledge base of pediatric environmental medicine for health professionals. 

About the program

The PEHSU Program was established in 1998 by the Agency for Toxic Substances and Disease Registry (ATSDR). The goal of the PEHSU Program is to increase awareness and knowledge of pediatric environmental health. PEHSU sites receive their funding from the ATSDR and the U.S. Environmental Protection Agency (EPA). Funds are administered through the American College of Medical Toxicology (ACMT) and the American Academy of Pediatrics (AAP).

The ACMT is responsible for the overall management of PEHSU activities in the western United States (Regions 6-10). MAPEHSU serves EPA's Region 7, which includes the states of Iowa, Kansas, Missouri, and Nebraska. Our mission is to provide expert clinical, consultative, and educational services to improve the recognition and treatment of children's environmental health problems in the mid-America region.
