Trunova I. Technogenum influence of cadmium and lead elements which situated in dumps of phosphogysum to the environment.

Thes is devoted to the research of technogenum influence of heavy metals which situated in dumps of phosphogysum to the environment. Cited data of world supply of phosphorus ores, the size of phosphorites extraction, the dynamic of using capacity. Analyzed chemical compound of phosphocontent raw materials in the way of containing heavy metals, given ecological estimation of the manufacture. Thes contain mathematic model, which determine functional dependence of content of investigating migrant in geochemical landscape from spatial coordinates and time. In the base of the experimental researches and results of mathematic model with the help of regressive analysis determined the form of the dependence between migration of heavy metals along the profile of soil and phosphogysum and the rate of migrant's accumulation in hard phase. Thes gave the investigation results of suggested anti-filtering screen along the bottom, inclinations and surface of phosphogysum dump and iron vitriol, which is recommended tostore inside of phosphogysum dump. The main words: technogenum influence, cadmium, lead, heavy metals, environment, phosphoresces, ecologically safety, phosphogysum, soil, migration.
