As a result, during the last decade many papers related to the iodine distribution in the global scale were published. Quantity and its distribution in the Earth's crust were estimated. In this article the mechanism of iodine aerosols origin and the role ofmarine organisms in this process were explained. Metastable compounds originated as a product of photolysis were identified; as a result a separate branch of science concerning their origin was created. The novelty is also identification of the anthropogenic radioactive iodine isotope 129I in natural environment. The isotope was applied in practice as a marker of contemporary geological processes dynamics and as an instrument of absolute age determination of geological formations in the lithosphere.}, title={Iodine occurrence in the natural environment}, type={Artykuł}, URL={http://czasopisma.pan.pl/Content/133665/PDF/4_GSM_23_2_2007_Przewlocki_Wystepowanie.pdf}, keywords={Iodine occurrence, iodine isotopes, iodine cycle, iodine chemistry}, }
