Title: Cumulative Risk Assessment (CRA) 2013 Webinar Series
Date: June 26, 2013
3:00 p.m. - 4:15 p.m. EDT
Location: Webinar

Join us for the monthly 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.

Invited speakers will present on a wide range of cumulative risk topics to inform participants about the development of the Agency’s CRA Guidelines.

The CRA Webinar Series will be presented monthly to run through December 2013. The CRA Webinar Series is open to the public to stimulate wider discourse on cumulative risk themes generally.

The June Webinar will feature:
