About the Human Health Risk Assessment Program
HHRA Mission Statement
The Human Health Risk Assessment (HHRA) research program will generate timely, credible human health assessments of individual chemicals and chemical mixtures to support priority EPA risk management decisions, thereby enabling EPA to better predict and prevent risk.
What We Do
The HHRA research program is one of six priority National Research Program areas with the U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD). The HHRA research program plays a unique role in serving the needs of EPA programs and regions, as weel as the broader risk assessment/management community, by identifying, evaluating, synthesizing and integrating scientific information on individual chemicals and chemical mixtures.
These state-of-the-science, independently peer-review human health assessments prepared under the HHRA research program serve as the foundation for EPA's regulatory and other decision-making to meet the Agency’s mission to protect human health and the environment.
