The Toxicology and Environmental Assessment Branch is composed of physicians, nurses, epidemiologists, researchers, analysts, industrial hygienists, environmental health specialists, and community outreach specialists who identify, control and prevent unwanted health effects associated with environmental hazards in highly burdened communities. For some communities, the essential elements for a healthy life are readily available; for others, the opportunities are significantly limited. The branch has several programs that work together to respond to emergent environmental and health hazards, while advocating for risk reduction and empowering communities so they can take actions to protect their health.
