Here’s the release from the Environmental Protection Agency:
[On April 8, 2021] the U.S. Environmental Protection Agency (EPA) [release] an updated toxicity assessment for perfluorobutane sulfonic acid (PFBS), a member of a larger group of per- and polyfluoroalkyl substances (PFAS). Today’s PFBS assessment is part of EPA’s commitment to restore scientific integrity to all of the agency’s actions and increase the amount of research and information available to the public on PFAS chemicals.
“This PFBS assessment reflects the best available science, involved extensive federal, state, and public engagement, and is critical to EPA efforts to help communities impacted by PFAS,” said senior career scientist Dr. Jennifer Orme-Zavaleta, Acting Assistant Administrator for the Office of Research and Development and the agency’s Science Advisor. “The assessment posted today fixes the errors in the version issued earlier this year, was developed by EPA career scientists, and upholds the values of scientific integrity. I’m proud to release such an important assessment that will help EPA and communities take action to address PFAS and protect public health.”
EPA, federal agencies, states, tribes, and local communities can use the PFBS toxicity assessment, along with specific exposure and other relevant information, to determine if and when it is necessary to take action to address potential health risks associated with human exposures to PFBS under appropriate regulations and statutes.
The assessment released today has gone through all appropriate reviews, includes input EPA received from external peer review, upholds the tenants of scientific integrity, was authored by expert career scientists in EPA’s Office of Research and Development, and has not been compromised by political staff – these were all issues with a version of the assessment that was posted during the previous administration. The release of today’s PFBS assessment upholds the integrity of EPA’s science, which EPA, states, tribes, and more rely on to make decisions that protect the health of their communities.
