Turning Science into Action

People are exposed to increasing amounts of toxic chemicals in air, food, water, personal care and cleaning products, at home and at work. The problem is so large, we cannot protect ourselves with individual actions alone - we need policy change.

That's why we share the science and best scientific methods to inform and guide policies that protect people from harmful chemicals, particularly those who are especially vulnerable such as pregnant people and children, and those who are disproportionately impacted.

Major Policy Areas

Chemicals and TSCA

We analyze federal chemical policy and EPA's implementation of the updated Toxic Substances Control Act, the law that governs regulations of chemicals in commerce.

Interwoven gears that each has a word such as assessment

Science Integrity

PRHE developed the Navigation Guide systematic review methodology to better evaluate the quality and strength of the evidence on how hazardous chemicals impact health.

Industry Documents

From lead and tobacco to hiding the truth about fossil fuels and climate, polluters have a long history of manipulating science and public opinion to maintain their corporate interests. We help gather these documents as part of UCSF's Industry Documents Library.

Policy Strategies

Public Comments

We monitor EPA and other regulatory body actions and comment on whether they are following the best science and protecting health. Public comments are essential to holding government agencies accountable. 

Capitol Dome

Legislative Briefings

PRHE planned legislative briefings to inform policymakers and staff about issues related to implementation of the Toxic Substances Control Act and science and decision making at EPA.


Science Action Network

PRHE launched the Science Action Network for Health and the Environment to bring together environmental health scientists to be a strong voice for science integrity and to prioritize health in chemical and environmental policy.
