Non-linear character of redistribution of chemical elements in the biosphere components as a result of the living matter activity

Modern problems of acceptable limits of techno-sphere impact on the biosphere, optimizing the interaction of techno-sphere and the biosphere, forecasting consequences of technogenic accidents in the environment and organization of rehabilitation in the post-accident period, place absolutely new demands for knowledge. These challenges require urgent development of new methodological foundations to study mass transfer and transformation of substances, the structure of global biogeochemical systems in the biosphere. Chemical composition of oceans and seas is a result of substance migration and transformation on biogeochemical river-sea and ocean- atmosphere “barriers”, i.e. in sites of “life condensation”. Stability of these processes is the main prerequisite of the hydrosphere ecosystem stability. The use of a methodology of empirical generalization has resulted in establishing a system of chemical elements’ distribution in the hydrosphere which possesses great predictive potentials.

A comparison of elements’ composition of different phases on the global level within the hydrosphere-lithosphere-soil-atmosphere systems enabled to reveal non-linear character of redistribution of different elements between these phases which reflects a general relative increase of concentration of trace elements in the environment of living organisms due to biogeochemical processes.  These processes are most active at the biogeochemical barriers, i.e. in the localities of "concentrated life" and are therefore inferred to result from the geologic activity of the ubiquitous living matter regulating its environment. The proposed nonlinearity index exhibits definite stability of the resulting living matter impact for different systems approximating 0.7: 1) 0.75 for proto lithosphere - sediment system; 2) 0.67 for river – ocean system; 3) 0.7 for ocean –– atmosphere system. The obtained value is believed to present a universal constant of biosphere reflecting biogenic stabilization of elements’ global cycles in the biosphere in the course of its evolution and corresponds to the biosphere concept of V.I. Vernadsky. The obtained values may be used as a reference values in estimation of the biosphere stability and anthropogenic contribution to transformation of the global biogeochemical cycles.
