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 includes participants from different parts of the state each year. If you would like to be notified when the CARE Study is in your area, email us at
