About the CARE Study
The California Regional Exposure (CARE) Study measures and compares levels of chemicals in people across the state. Information from the CARE Study can support policy makers and communities in taking action to protect our environment and health.
The study will measure levels of selected metals and perfluoroalkyl and polyfluoroalkyl substances (also known as PFASs). The CARE Study was launched in 2018 in Los Angeles County, and we visited Riverside, San Bernardino, Imperial, Mono, and Inyo counties in 2019.
The CARE Study will be in San Diego County and Orange County in 2020. Study participants will receive a $50 gift card. Participants will also have the opportunity to find out about the levels of chemicals in their bodies, and learn about actions they can take to help reduce contact with chemicals.
Let us know you're interested
- If you are interested in volunteering for the study, let us know by completing the online interest form (link is external). If you cannot access the interest form online, or if you would prefer to speak with our study staff, please call 510-367-4166 or email CAREStudy@cdph.ca.gov.
- The interest form is currently open to adults who have lived in San Diego County or Orange County for the past year. The CARE Study will be in other counties in future years!
- Beginning in January 2020, we will send invitations to join the study. We will select people to reflect the population of San Diego County and Orange County.
Your role in the study
Study participants will:
- Sign a consent form. The consent form gives you information about the study, and tells us that you agree to participate.
- Fill out a survey. The exposure survey gives us information about how you may have come into contact with (or, "have been exposed to") chemicals. We will ask you questions about your diet, hobbies, jobs, and home.
- Go to one appointment. You will give both blood and urine samples at your appointment, and answer a few short questions. You will receive your $50 gift card at your appointment.
Receiving your study results
If we find high levels of lead, mercury, arsenic, or cadmium, we will send you a letter and/or call you as soon as possible. That is because these chemicals are linked to known risks to health.
All other results are available 8-12 months after your appointment. You can tell us if you want your results on the consent form, or you can contact us at 510-367-4166 or CAREStudy@cdph.ca.gov.
