A coalition of interested parties is being formed to explore and possibly resolve the conundrum in human 1/2 life for perfluorooctanote (PFOA), which is reflected in differences in safe doses world-wide of 750-fold (Mikkonen et al., 2020). A recent paper has been submitted that addresses this conundrum in part (Dourson and Gadagbui, 2021). This collaboration started in April of 2021 with nominations to an advisory committee* who will then lead the coalition through a series of virtual and possibly face-to-face meetings, with conclusions expected later this year. Toxicology Excellence for Risk Assessment (www.tera.org) has been designated as the nonprofit organization to support this coalition by the ARA Steering Committee (https://tera.org/Alliance%20for%20Risk/ARA_Steering_Committee.htm). Because TERA is a 501c3 nonprofit organization, all donations to this effort are tax deductible.
For interest in joining the coalition, please contact Michael Dourson at firstname.lastname@example.org.

*Advisory Committee: Nominations to this advisory committee are welcome by the end of April 2021. Selection of members for this committee will be made during first week of May 2021 by the ARA Steering Committee.
