Geokhimiya Vzaimodeystviya Rudnichnogo Drenazha S Prirodnymi Vodoemami

Tekhnogennye potoki rudnichnogo drenazha predstavlyayut soboy problemu mirovogo masshtaba, poskol'ku skladirovannye otkhody dobychi i pererabotki rud poleznykh iskopaemykh yavlyayutsya postoyannym istochnikom mnogikh toksichnykh elementov, vynosimykh v okruzhayushchuyu sredu vodnym transportom. Vsledstvie okisleniya sul'fidov, soderzhashchikhsya v otkhodakh, obrazuyutsya sul'fatnye vody razlichnoy kislotnosti s vysokim soderzhaniem zheleza, margantsa, khal'kofil'nykh i litofil'nykh elementov (Zn, Cd, Cu, Pb, Al i dr.), kotorye po sostavu rezko otlichayutsya ot prirodnykh rechnykh vod (po fiziko-khimicheskim usloviyam, urovnyu mineralizatsii, lidiruyushchim makrokomponentam, soderzhaniyam rudogennykh i litofil'nykh metallov). Tekhnogennye potoki vklyuchayutsya v gipergennye tsikly migratsii, v rezul'tate chego sushchestvennym obrazom menyaetsya ne tol'ko gidrokhimicheskiy tip prirodnykh vod, no i sostoyanie landshaftov na sopredel'nykh territoriyakh.
