Environmental Health

CDC’s National Report on Human Exposure to Environmental Chemicals provides an ongoing assessment of the U.S. population’s exposure to 148 different environmental chemicals.

The places where people live, work and play can greatly impact their health. CDC conducts research that analyzes to what extent these possible environmental threats affect our health and who may be most at risk. The CDC Foundation helps CDC collaborate with universities and research institutions in the U.S. and around the world to investigate potential environmental health threats and make recommendations for how to mitigate their affects on our health.
