Keywords: fluorine, technogenic pollution, woody plants


The influence of aluminium smelters’ atmospheric emissions on the fluorine accumulation by soil and plants and also on the changing of chemical composition of the leaves of woody plants was studied. It was determined that ratio of total fluorine to extractable fluorine was changing greatly depending on the specie of the plant. High ash content in leaves (due to K, Р, Са, etc.) and increasing of ratio of total fluorine to its water-soluble part is characteristic of gas-resistant plants. Plants’ resistance to fluorine depends on the ability of an organism to transform a toxicant into insoluble forms that do not take part in physiological processes. In other words, it depends on the presence of the elements with high precipitating capability in plant tissues. It was stated that gas-resistant species possess the ability to limit the fluorine penetrating into a plant through the roots, and also to constrain its migration within the plant (especially in organs that determine the further development of the plant).
