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, ...

The degree of toxic metals contamination in water, vegetables and respective soils in the studied area - KCM Smelter site - Plovdiv-Assenovgrad is evaluated in individual and integral aspects. The analytical measurements were performed by inductively coupled plasma atomic emission spectrometer (ICP-AES), Jobin Yvon ULTIMA 2. The analysis lines in the determination of impurities were selected in view of spectral interference. Ground, surface, waste - water and some corresponding soil samples were investigated for m...

Chemical species of existence and migration of water metal pollutants in solution and suspension in the significantly contaminated Plovdiv – Assenovgrad area are identified in their dynamics. Underground, surface and technological waters in their geochemical context are investigated (more than 2 000 data) as a ground of the speciation study (30 trace and 24 major elements). All the trace elements analytical researches are carried out by HR-ICP-AES Jobin Yvon ULTIMA 2 and the speciation study – by WATEQ 4F adap...

The degree of heavy metal (+As) water and vegetable contamination due to mining and metallurgical activities in the studied area is evaluated in individual and integral aspects. 267 ground, surface and waste water samples, according to the proposed grid, were investigated for trace elements, 56 of them for 34 elements: Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sb, Zn, Hg, Be, B, V, Sn, Mo, Se, Ag, Te, Tl, Ti, U, Ca, Li, Mg, Sr, Bi, Ga, In, K, and Na. The analytical work is performed with inductively coupled plas...
