Help Advance the Risk Assessment of Chemical Mixtures

Eric Van Genderen and Mary Ann Ottinger, Meeting Co-chairs

SETAC North America is conducting a Focused Topic Meeting on Risk Assessment of Chemical Mixtures from 6–8 September in Denver, Colorado, USA. The purpose of this meeting is to analyze the interplay between scientific knowledge on the environmental hazard, exposure and risk of chemical mixtures and its consideration in chemical regulation and management. The meeting will build upon the gaps, trends and findings identified in past workshops (e.g., SETAC Pellston Workshop, SETAC Special Science Symposium, EFSA Colloquium) to establish the current state of the science regarding mixture risk assessment and chemical management.

The meeting will cover the following:

  • An overview of previous workshops and symposia to establish background knowledge on the subject of mixtures risk assessment
  • Current regulatory perspectives on mixtures risk assessment and the challenges of integrating the science of mixture toxicology into regulatory frameworks from multiple jurisdictions (Australia, Canada, Europe and the USA)
  • Information and overview on recent advances in our scientific understanding of mixture toxicology
  • Perspectives of what tools are currently available to assist in more accurate predictions of risk

A major focus of the meeting will be to explore options on extending the scientific evidence collected during the last years for developing useful regulatory frameworks for assessing combined exposures.  

This meeting will provide information on the latest advancements in fundamental and applied research that enable risk managers to make well informed decisions. Technical sessions, including posters, will examine mixtures through the lens of the risk assessment paradigm and will include topics such as problem formulation, exposure assessment, effects assessment, risk assessment, risk management and case studies.

Abstract submission and meeting registration are currently open. The program also includes invited speakers, who are leading experts in the field and represent a variety of disciplines, geographies and sectors. Invitees include Gary Ankley, U.S. Environmental Protection Agency (USEPA); Thomas Backhaus, University of Gothenburg; Karen Eisenreich, USEPA; Mick Hamer, Syngenta; Thomas Harthung, Johns Hopkins; Juliane Hollender, Swiss Federal Institute of Aquatic Science and Technology (EAWAG); Travis Schmidt, U.S. Geological Survey; Emma Schymanski, EAWAG; and Mark Stynar, USEPA.

Please submit your abstract by 29 June, register for the meeting, and we’ll see you in Denver!
