Participation in this interest group is open to all interested parties. If you are not already a member, make sure you are signed in to your SETAC account then click "Join Group” near the top of this page.


The purpose of the Global SETAC Interest Group on Bioaccumulation Assessments (‘B’ SIG) is to advance the state of bioaccumulation science, and increase the use of sound science in decision-making through the use of models, in vitro, and in vivo data for bench-scale, site-specific and regional bioaccumulation assessments.


The ‘B’ SIG’s overall mission is to identify and communicate with decision-makers, thought leaders, and interested scientists that can create and apply information on new bioaccumulation-related tests and assessment approaches.

The ‘B’ SIG coordinates the organization of technical sessions at all regional SETAC meetings and holds regular business meetings with its membership at all SETAC meetings.

The ‘B’ SIG hosts workshops for scientists on emerging issues and short courses for educators and stakeholders needing to explain and help incorporate new testing or tiered approach assessment methodologies into current assessment paradigms.

The ‘B’ SIG actively works with other entities involved in advancing bioaccumulation science to take advantage of the authoritative experts, thought leaders, and decision-makers in SETAC, representing many environmental science disciplines and types of work (educators, regulators, government and academic researchers, industry scientists).

The activities and relationships between the ‘B’ SIG and other entities during 2004-2008 indicate that relationships with these entities are likely to continue in the future:

  • Cross-sector groups – Health and Environmental Sciences Institute (HESI)
  • Professional societies – Society of Toxicology (SOT), American Chemical Society (ACS - Environmental Chemistry section)
  • Government groups – European Chemicals Agency (ECHA), European Centre for the Validation of Alternative Methods (ECVAM), US Environmental Protection Agency (USEPA), Environment Canada, Netherlands National Institute for Public Health and the Environment (RIVM)
  • Industry groups – Research Institute for Fragrance Materials (RIFM), European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC), Environmental Risk Assessment and Management (ERASM), European Chemical Industry Council (CEFIC), Canadian Industry Coordinating Group (ICG), and Soap and Detergent Association (SDA).


The Global SETAC Interest Group on Bioaccumulation Assessments (‘B’ SIG) was initiated in 2005 by Annie Weisbrod from Procter and Gamble and she served as constituting chair together with Mark Bonnell from Environment Canada.

Organization and operating principles


  • Any SETAC member may participate in activities organized by the ’B’ SIG. ‘B’ SIG events may be attended by non-SETAC members as well. Participants will include experts in the field of bioaccumulation as well as representatives of ‘user groups’ for related models or tests.
  • SIG members may be solicited, in particular, to overlap with other entities working to advance the field of bioaccumulation assessment.
  • The SIG’s activities are guided by a "Steering Committee” of SETAC members from the larger pool of people attending sessions, meetings, and otherwise contributing to the ‘B’ SIG’s goals.

Governance by Steering Committee

  • Roles – The ‘B’ SIG Steering Committee has three primary roles:
    • to identify priorities for research and conceptual development in the field of bioaccumulation,
    • to arrange presentation sessions and other activities at annual meetings to focus on these priorities,
    • to actively communicate with and include members from all sectors and regions.
  • Members must have a commitment to the purpose and operating guidelines of the ‘B’ SIG, and commit to actually contributing to support the ‘B’ SIG
  • Composition – the Steering Committee is comprised of 12 organizers from government, industry, academia, and other stakeholders. As it is a global SIG, the committee must include organizers from several geographic units. Announcements of openings for new Steering Committee members will be circulated via SETAC communities webpages with applications sent to the Steering Committee for review. If more applications are available than positions, new members are selected by voting of the SAG mailing list.
  • Duration - The ‘B’ SIG Steering Committee members serve a three-year term. The initial members stagger their leaving the committee to ensure turn-over of approximately one-third members per year. Terms begin and end with the calendar year (Jan – Dec).
  • Role of Chair - The SIG chair is responsible for preparing and submitting the annual reports to the SETAC World Council (SWC) and for organizing the business meetings at all international SETAC meetings. The chair is appointed by the SWC, based on recommendations from the Steering Committee who will consult with ‘B’ SIG members.
