Fluorine in water bodies of the Matua island (the Central Kuriles)
Abstract
The first data on fluorine content in surface (streams, lakes) and ground (springs) waters of the Matua Island were obtained. The fluorine concentration is from 9.2 to 307 mg F/l, averaging ~95 mg F/l, which corresponds to the average value for World Rivers, but is 1,5–2 times lower than the average fluorine content in river waters of Japan and Kamchatka. It was concluded that the main sources of fluorine on the island are cyclic sea salts, soluble weathering products and volcanic exhalations, which play an important role even during the period of low volcanic activity before next eruption of the Sarychev Peak volcano.
Supporting agencies: The study was financially supported by the Russian Foundation for Basic Research (project № 18-05-01133) and the Russian Geographic Society (grant № 02/2017-R).
