Key Themes of IRARC Research
• Incorporating new science into environmental
risk assessment and risk management.
• Identification of susceptible populations that are
at greater risk to environmental exposures
• Types of exposures
• Differential hazards
• Need to understand mechanisms of response
and effect at multiple levels of biological
complexity

Multidisciplinary and Cross-agency
partnerships are an essential part of IRARC
Example Agency Groups/partnerships
• NIEHS/EPA Children’s Health Centers
(CHC Center )
• NSF/NIEHS Oceans and Human Health Center
(H20 Center)
• Joint Carnegie Mellon/UW Center for the Study and
Improvement of Regulation (CSIR)
• NIEHS Toxicogenomics Center (TRC)
• Department of Energy Consortium for Risk Evaluation

Is there a potential problem?
What is the problem?
Who has the problem?
How bad is the problem?
• What should we do about it?
• What should we say?
• Who should we inform?
