Western States Pediatric Environmental Health Specialty Unit

Welcome to the Western States Pediatric Environmental Health Specialty Unit (WS PEHSU) at University of California San Francisco. Our purpose is to provide expertise and resources on the connection between pediatric and reproductive health and the environment.

Children have higher exposures to environmental contaminants than adults and they are also more vulnerable to the health effects of those exposures because they are still developing. The WS PEHSU works to reduce these risks by:

  • providing training for health professionals
  • offering consultations to families and communities and
  • developing educational resources on environmental health issues that affect children.

The WS PEHSU was created when the University of California, San Francisco PEHSU and the University of California, Irvine PEHSU were merged in 2015. We serve clinicians and the community in California, Nevada, Arizona, Hawaii, Guam, American Samoa, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia, the Republic of Palau, the republic of the Marshall Islands and more than 150 tribal nations contained therein (Region 9).

We are part of a network of PEHSUs across North America dedicated to providing expertise on the connection between reproductive  and children’s environmental health, and the environment. This site connects you to information and resources on a variety of environmental health topics and describes current activities of the WS PEHSU and how to contact us for services.

The WS PEHSU exists to improve the recognition and management of environmental health problems among children. This page contains information relevant to clinicians regarding the latest research and recommendations relevant to protecting children from specific environmental contaminants. We also provide educational resources for clinicians to further explore the impacts of the environment on children’s health.

This page provides information for the general public on protecting families from harmful environmental exposures. Our resources include articles, videos, and fact sheets on specific environmental health topics. These pages also connect to additional resources and organizations focusing on children’s environmental health.
