    Summary
    This summary is machine-generated.

    High fluoride in drinking water in Senegal causes dental and skeletal fluorosis in children and adults. Current World Health Organization guidelines may be unsuitable for hot climates.

    Area of Science:

    • Environmental Health
    • Public Health
    • Toxicology

    Context:

    • Fluoride is a naturally occurring element in drinking water.
    • High fluoride intake can lead to adverse health effects.
    • Climate significantly influences water consumption and fluoride exposure.

    Purpose:

    • To assess the prevalence of dental and skeletal fluorosis in relation to drinking water fluoride levels in Senegal.
    • To evaluate the suitability of current drinking water fluoride guidelines in hot climates.

    Summary:

    • A survey in Senegal revealed high prevalence of dental fluorosis (up to 100%) in children and skeletal fluorosis (kyphosis) in adults exposed to elevated drinking water fluoride (1.1–7.4 mg/l).
    • Dental fluorosis was observed at 1.1 mg/l, while severe forms and skeletal fluorosis occurred at higher concentrations.

  • High ambient temperatures likely exacerbate fluoride toxicity through increased water intake and sweat loss.

    • Impact:

    • Findings suggest current World Health Organization guidelines for drinking water fluoride may be inadequate for regions with hot, dry climates.
    • Highlights the need for localized fluoride exposure assessments and potential guideline revisions.
    • Informs public health strategies for managing fluorosis risk in similar environmental conditions.
