Abstract—
A hypothesis was proposed that a considerable amount of gaseous HF is supplied to the atmosphere from the soil cover owing to the reaction \({{{\text{H}}}^{ + }} + {{{\text{F}}}^{ - }} = {\text{HF}}{\text{.}}\) In the upper layer of tundra and taiga soils with pH 4.0–4.5, the partial pressure of HF is (65–20) × 10–12 atm. Correspondingly, the concentration of dissolved F in the condensates of water vapor is 1.6–11 μg/L, which is comparable with F concentration in rainwater.
