Are there chemicals in your body that could harm your health?

Join the California Regional Exposure (CARE) Study to find out more.

The CARE Study is measuring levels of chemicals in people across the state. We also collect information from participants, like their hobbies, the jobs they do, and the places they live, that can help us understand how people come into contact with chemicals. The CARE Study will also help us learn if there are areas of California where people have higher levels of chemicals in their bodies.

The CARE Study launched in Los Angeles county in 2018. We visited Riverside, San Bernardino, Imperial, Mono, and Inyo counties in 2019.

Do you live in San Diego County or Orange County? The CARE Study is headed your way soon! Let us know you're interested, and we'll notify you when the study begins.
