EXPERIMENTAL MODELING OF INTERPHASE AND BACTERIA INTERACTIONS IN HEAVY METAL AND AS POLLUTED AREA
Abstract
Experimental modeling with the aim of elucidation of the geochemical behaviour of heavy metal pollutants (Pb, Zn, Cd, Cu, Ni, Mn, Fe) and As during interphase processes in metallurgy contaminated area are carried out in 3 aspects: I. Water-soil interaction chemical simulation: 3D –lixiviation of soils and acid rain impact modeling, revealing consequences for a secondary remobilization and increasing the environmental risk for groundwater, vegetables, etc. II. Sorption ability of soils with fixing possibilities, concerning metal pollutants and As and existence of geochemical barriers against the penetration in the aquifers. The most polluted soils in the Pb-Zn smelter vicinity present decreasing of the sorption capability and some “permeability”. III. The experimental simulation of water-waste clinker interaction indicates very active elution of heavy metals and As, causing a significant secondary contamination of surface and groundwaters, soils and sediments. Heavy metalbacteria interactions play a significant role in migration and detoxication of the metal pollutants in the area by biotransformation. The basic importance for understanding the biogeo- chemical processes and a perspective for low-cost bacteria-based bioremediation of heavy metal pollution of waters and soils are shown.
