Biogeochemistry
Biogeochemistry is a branch of geochemistry associated with biological sciences. The founder of biogeochemistry was Volodymyr Ivanovich Vernadsky, who in 1918 organized the first biogeochemical laboratory in the world in Kyiv. Biogeochemistry studies: the chemical composition of living matter, the influence of living matter on the history of earth's chemical elements, their migration, distribution, dispersion and concentration in the earth's crust, that is, the geochemical processes of the biosphere. The main mass of living matter are those chemical elements that easily form atmospheric gases or water-soluble ions - the main anions of the water of the hydrosphere; K +, Na +, Mg2 +, Ca2 + - the main cations of the lithosphere.
