 Message from ISCHE President - Dr. Wendy Heiger-Bernays

As we head into 2022, we face a myriad of challenges. Some are daunting - climate, COVID, chemicals/plastics and their impacts on children across the Globe. And some of these are the challenges in our day-to-day lives as we worry about our own children, our parents, our friends, our partners and our communities. I am buoyed by the commitment that I see - in our Board members, our Senior Advisors and our members. Our work in environmental health has never been easy, but we are driven by the science demonstrating the impact of the environment on children and the potential for improvement!  In 2022 we have many opportunities, some are highlighted in this newsletter, to work collaboratively towards our collective goals - I am hopeful that you will be able to participate in one or many of the amazing efforts in which ISCHE is engaged. And, if you are not able at this time, perhaps send me an email, say hello and let me know if you think we are heading in the right direction! 

Wishing you a year of good health!

 Welcome Interim Vice President: Dr. Christine Till

Dr. Christine Till is an associate professor of Psychology at York University and clinical neuropsychologist. In 2019, she was awarded the President’s Emerging Research Leadership Award at York University.

Dr. Till has been spearheading a research initiative funded by the Canadian Institutes of Health Research (CIHR) and NIEHS to examine the neurotoxicity of fluoride in pregnancy and across the lifespan. Her research leverages epidemiological cohorts from Canada, the USA, and Mexico City. Her research on fluoride has been published in leading scientific journals and continues to attract international attention for its public health relevance.

Call for Self-nominations to Membership on the ISCHE Fluoride Committee

At its November meeting, the ISCHE Council approved the charge to a committee that will evaluate the evidence that prenatal and early postnatal exposure to fluoride is associated with neurodevelopmental toxicity. The approved charge is as follows:

The ISCHE Fluoride Committee: Rationale and Charge 

Rationale: The field of public health continues to evolve and must always be open to review of existing policies as new evidence accumulates.  Fluoride policy has been a contentious topic for many decades.  Recent epidemiologic studies suggest that adverse neurodevelopmental effects occur at current population levels of prenatal and early childhood exposure. There is no consensus, however, on whether these studies are sufficiently conclusive to warrant consideration of whether the purported benefits of fluoride exposure to pregnant women and young children outweigh the risks.  Given the enormous implications for public health and practice, it is urgent that all aspects of this issue be carefully evaluated by those with the requisite expertise.  ISCHE can contribute to this discussion by bringing to bear the knowledge and experience of its members in conducting epidemiological studies of the neurodevelopmental toxicity of chemicals.  


Charge: The ISCHE Fluoride committee will focus on the potential neurodevelopmental toxicity of fluoride exposure in the prenatal and early postnatal period (i.e., prior to tooth eruption, approximately 6 months of age).  The committee will prepare a statement that:

  1. Summarizes the current state of epidemiologic research on fluoride neurodevelopmental toxicity (including characteristics of the dose-effect relationship, potential critical windows of vulnerability, sensitive subgroups, etc.).
  2. Identifies critical knowledge gaps about fluoride’s neurodevelopmental toxicity. 
  3. Proposes strategies that could enhance the rigor of future studies of neurodevelopmental toxicity and fill the knowledge gaps.  
The ISCHE Fluoride committee will not itself evaluate the evidence regarding the benefits of fluoride exposure in pregnant women and young children.  At the discretion of the Chair, however, the committee can include as part of its statement consensus/position/policy statements published by dental and pediatric organizations (e.g., the American Academy of Pediatrics, CDC, the US Preventive Services Task Force) on the use of fluoride exposure in the prenatal and early postnatal period. 

Committee Selection and Membership: The Committee will include up to 10 members and will meet by teleconference (Zoom) once per month for two hours for a period of approximately one year. This might be extended depending on the Committee’s progress. Some work will likely be required between Committee meetings. Although the Committee will be limited to ISCHE members, individuals with critical expertise that ISCHE members do not have will be consulted on an as-needed basis. The product will be a statement that addresses the three elements of the charge. The statement will be submitted to the ISCHE Council for review (which might include requests for revision) and approval to submit it for publication. Members of the Committee will be listed as authors of the statement “on behalf of ISCHE.”

For the Committee to complete the work reflected in the charge, expertise will be needed in environmental epidemiology, neurotoxicology, neurodevelopment, exposure assessment, fluoride pharmacokinetics, pregnancy, and public health policy.  If you are interested in applying for membership on the Committee, please send your CV and a brief description (<250 words) of your expertise relevant to the Committee’s charge to the chair, David Bellinger, who will make the decisions about the composition of the Committee. All materials should be sent to David Bellinger ( with the subject: ISCHE Fluoride Committee by February 1st, 2022. 

Early career members are encouraged to apply.  Applicants should disclose any public statements (including publications, testimony) that he or she have made, if any, pertaining to fluoride developmental neurotoxicity. Such activity will not necessarily disqualify one from membership on the ISCHE Committee but will be helpful in ensuring that the Committee is balanced in terms of public positions that Committee members have taken. The disclosures will be provided to all Committee members, as is routinely done for committees of the National Academies and other organizations. These disclosures will also be included in the publication of the ISCHE policy statement on fluoride.
