A message from the Environmental Protection Agency:

Join us for the monthly Cumulative Risk Webinar series presenting the latest research findings in cumulative risk assessment and impacts. EPA’s Risk Assessment Forum Cumulative Risk Assessment (CRA) Technical Panel is currently developing guidelines on CRA and NCER is funding extramural research to advance the science further and introduce additional strategies for examining combinations of chemical, physical and biological stressors while factoring in population vulnerabilities.


This Webinar is being conducted under EPA’s Sustainable and Healthy Communities

(SHC) Program. The purpose of the SHC program is to conduct research that will result in science-based knowledge to guide decisions that will better sustain a healthy society and environment in America’s communities. SHC’s outputs will help inform decision-makers as they make choices that meet regulatory mandates and will sustain positive human health outcomes and well-being, environmental quality, and economic resilience.
