Raising of problem. The modern industry needs initiate amplification of the technogenes is intensity that affects the processes of the micro- and ultramicroelements migration and lead to accumulation significant quantities of the ele-ments of the first class of toxicity on the Earth surface, which primarily include heavy metals Ecological peculiarities of the technophiles elements, as long half-life in the environment (for Cd ? 155 years, Zn ? 500 years Pb ?up to several thousand years); biophylly reflected through toxicity to living organisms; ability to induce carcinogenic and mutagenic effects; concentration in food chains, cause extreme danger to humans and biota. Low utilization of the heavy metals from the raw promotes their dispersion in the biosphere and the formation of technogenic geochemical anomalies. Purpose. Conduct an ecological assessment of the heavy metals (Cd, Pb, Zn, Mn and Cu) technogenes is by examining biogeochemical parameters on the global planetary level, both those relating directly to the properties of metals, and those related to human activities and including of these toxic elements in the industrial products and waste. Conclu-sion. Technogenesis of the heavy metals has increased significantly during the twentieth century. According to the posi-tive nature of the tehnophyllya symmetry relative to the average, intensity of the Pb and Cd inclusion with the man-made stream the biogeochemical cycles occurred more gradually than Zn, Cu and Mn. Destruction activity of the chemical elements changed in some Pb > Cu > Zn > Cd > Mn in the early twentieth century, Cd > Cu > Pb > Zn > Mn ? in the twentieth, showed establishing of the toxic, carcinogenic and mutagenic properties of the lead, so mankind has realized the risk of the biosphere and it is subsequent biogenic migration in the food webs. For load of the techno-genic module has been installed increasing the intensity distribution of heavy metals in the noosphere and has been proved by comparison of the chemical elements in the waste production and product after its life with clarkin the litho-sphere possibility of recuperation and recycling, so use these valuable components in future production.
