Development of Methods for a Tiered Approach to Assess Bioaccumulation of Chemicals Committee

Note: As of 2022, the former Animal Alternatives in ERA and Bioaccumulation Committees have merged to form the Next Generation ERA Committee

Mission Statement

The mission of the HESI Development of Methods for a Tiered Approach to Assess the Bioaccumulation of Chemicals Committee is to develop the tools needed for assessing the potential bioaccumulation of organic chemicals.

Working Groups

  • Bird Biotransformation and Toxicokinetics

    This working group is exploring the state of the science on biotransformation and toxicokinetics in birds. A literature review on bird bioaccumulation and biotransformation was funded by the committee and completed by Dr. Dave Kuo (City University of Hong Kong/Kuo Research and Consulting). This review involved evaluation of >550 peer-reviewed studies resulting in a database of >25,000 data entries on >700 organic compounds for nearly 500 wild and domestic bird species. Dr. Kuo is now leading the development of a manuscript to describe this effort, establish the state of the science in the field, and provide recommendations for future research.

  • Invertebrate Biotransformation and Toxicokinetics

    This working group is exploring the state of the science of biotransformation and toxicokinetics of organic chemicals in aquatic invertebrates. A literature compilation was conducted for 11 genera of invertebrates. The literature is currently being reviewed and biotransformation and toxicokinetics data are being extracted and stored in a database. This work, funded by the committee, is being conducted at the University of Hong Kong by two of Dr. Dave Kuo’s students.

  • Fish Biotransformation and Toxicokinetics

    The committee held an expert workshop in October 2019 on fish biotransformation in bioaccumulation, aimed at identifying short-, medium-, and long-term needs for research and coordination in this space. Approximately 35 experts from industry, academia, and government attended, and several publications and research programs will be initiated in the coming months. The committee will work to identify feasible next steps for additional data generation and analysis over the next year related to fish biotransformation and toxicokinetics. The group is preparing a manuscript on the current use and application of the in vitro test method.

Once they are released into the environment, a number of chemicals are known to bioaccumulate in organisms, sometimes to concentrations that may threaten the individual or their predators.

Use of Trophic Magnification Factors and Related Measures to Characterize Bioaccumulation Potential of Chemicals

Integrated Environmental Assessment and Management, 2012

Conder JM, Gobas FA, Borgå K, Muir DC, Powell DE
  • HESI - Health and Environmental Sciences Institute

Recent technical workgroups have concluded that trophic magnification factors (TMFs) are useful in characterizing the bioaccumulation potential of a chemical, because TMFs provide a holistic measure of biomagnification in food webs.
