Welcome to the University of California, San Francisco, Pediatric Environmental Health Specialty Unit (UCSF PEHSU).

We are part of a network across North America dedicated to providing expertise on the connection between children’s health and the environment. Children are uniquely vulnerable to environmental contaminants because they are still developing and their behavior can expose them more hazards. The UCSF PEHSU aims 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.

This site connects information and resources on a variety of environmental health topics and describes current activities of the UCSF PEHSU.

New eBook: A Story of Health preview (pdf)
September 2014
The first installment of a new eBook on how to promote health and prevent disease will soon be available. The book uses a series of case vignettes to highlight how our environments – the natural, built, chemical, food, economic, and social environments – affect our health across the lifespan and how these different environments interact with genetics and each other to influence health. The book explores the potential environmental causes of common diseases and conditions such as asthma, developmental disabilities, cancer, infertility, diabetes, and cognitive decline and how to prevent them and promote health by shaping the environments where we live, eat, work, play, pray, volunteer, gather and socialize. Its intended audience includes clinicians, health advocates and policy makers. It will eventually also be available with free continuing education credits for health professionals. Preview the e-book (pdf).
