Fluorine Content in Surface Waters of the World Ocean

Fluorine concentrations and F/Cl mass ratio values were determined in 40 samples of surface waters of the Indian and Atlantic oceans and of the Red and Mediterranean seas. A weak trend of increasing F/Cl ratio with an increase in chlorinity (salinity) was established, which in absolute value slightly exceeds the measurement error. An assumption was made about the influence of the influx of atmospheric aerosols and calcium carbonate precipitation on the fluorine content and F/Cl ratio in the surface horizons of the water column.
