Health and Environmental Risk Assessment Strategic Research Action Plan 2019-2022

HERA National Research Program StRAP cover
To protect human health and the environment, EPA and its federal, state, and other government partners and external stakeholders must make critical decisions about the risks of exposures to environmental stressors. Since assessments form key components of the scientific foundation for risk assessment decisions, they can have significant implications for the protection of public health and the environment, as well as for the economy and sustainable development.

The Health and Environmental Risk Assessment (HERA) research program has been designed to develop and apply state-of-the-science research to characterize impacts on human and ecological systems – whether they result from exposure to single, complex, or multiple physical, chemical, or biological stressors – to support and improve EPA’s risk assessment decisions.

The HERA StRAP outlines EPA's research to identify, evaluate, and integrate existing and emerging information from diverse scientific disciplines to rigorously characterize hazard and evaluate exposure-response relationships in support of human health and environmental risk assessments.
