- • Mineralogy, precipitation and weathering influence background soil fluoride.
- • Geochemical regression tree models can predict background fluoride in soil.
- • Fluoride in subsurface soils exceeded recommended ecological risk thresholds.
- • Phosphate fertiliser indicated to be a potential source of added fluoride to soils.
