Findings from the California Regional Exposure (CARE) Study

What have we learned from the CARE Study?

As part of this biomonitoring study, hundreds of volunteers donated urine and blood samples to be tested for metals and other chemicals of concern, including PFASs (perfluoroalkyl and polyfluoroalkyl substances). Biomonitoring California hosted a webinar to present findings from the CARE Study on Thursday, April 18, 2024, from 1:00 – 2:00 pm. At the webinar, we shared what we have learned about exposures to these chemicals in California, and how this information can be used to make a healthier state and future for all Californians. The webinar presentation can be viewed here: CARE Study webinar slides (PDF; 7MB).
