A high content of fluorine was found in ornithogenic soils around penguin rookeries on King George Island. South Shetland Islands. Fluorine is inherent in 0.11% in krill (Euphausia superba). eaten by penguins. Fluorine content in penguins excreta increased approximately to 0.43%. and after decomposition and leaching to 1.03%. The concentration grew during mineralization of organic matter in guano (up to 2.2%). In a surface layer of guano fluorine occurred in apatite. A phosphatization was noted in a subsurface zone as the result of a reaction between guano leachates and weathered volcanic rocks. In the upper part of this zone near the large rookeries a fluorine occurred in minyulite (aluminium phosphate containing potassium and fluorine) and fluorine content here reached 3.5%. Sometimes fluorine was also bound with amorphous aluminium phosphate (up. to 2.0%). formed as a result of incongruently dissolving of minyulite in pure water.

Research results of fluorine accumulation in fallow deers bones in Western Pomerania were presented. Fluorine contents denotation was made by potentiometer method with ioneselective elektrode use. Dependence of fluorine accumulation on age and individual features of animals, regions properties of investigated area and distances from emission sources of fluorine compounds were examined. Dependences characteristic for probabilistic variables were obtained. For measurements results description were used neural networks MLP, RBP, GRNN.

This study examines the optimal parameters for obtaining fluorine-doped SnO ₂ (FTO) films with promising potential for photovoltaic applications. Due to its properties, tin oxide is used in a wide range of technologies, among which the manufacture of solar cells is one of the most important. Being doped with fluorine, tin dioxide becomes a good transparent and conductive electrode, suitable for solar cell applications. The chemical stability and low cost of the doped SnO ₂ makes it an advantageous alternative to tin-doped indium oxide (ITO). Among the most important characteristics of FTO thin films are high photoconductivity under sunlight irradiation and strong UV absorption. The SnO ₂ compound, doped with fluorine, exhibits a considerable chemical and physical stability, good electrical conductivity and high transmission (over 85%) in the visible range. The spray pyrolysis technique is the most preferable and efficient deposition method of fluorine-doped SnO2 thin films. This work aims to identify the optimal parameters for the spray pyrolysis of SnO ₂:F films and to analyze the morphology, transparency and strength of as obtained films in relation to the doping amount in the precursor solution, spraying distance and film thickness.

The measurement of SO2, and fluorine compounds concentrations in the air at 8 points on the King George Island, South Shetland Islands, were done in January and February 1979. The received values were similar to the ones for regions recognized as the world background areas. The activity of the Polish Antarctic Station did not influence the air pollution status neither in its surroundings, nor in penguins colonies and extinct volcano areas on Penguin Island.
