(38-56) Contaminated of soil in Kryvyi Rih mining industrial region (Ukraine) by heavy metals mobile forms . Savosko, Vasyl*,1, 1 Kryvyi Rih Botanical Garden, National Academy of Sciences, Kryvyi Rih, Ukraine ABSTRACT- In Kryvyi Rih ore mining industrial region every ear in atmospheric air been rejected 0.08-0.11*106 tones of industrial dust, which containing many heavy metals. Therefor now, very actual are investigation of the heavy metals in mobile forms in the soil of this region. Aerogenous (with atmospheric air) entering of the heavy metals to soil had been investigated. The mobile forms of heavy metals (Fe, Mn, Zn, Ni, Cu, Pb, Cd) which were extracted from soil by an one-normal nitrogen acid. The obtained results have been demonstrated that in contaminated land the accumulation and leaching of the heavy metals mobile form takes place. In chernosem ordinary contents Fe, Zn, Ni in 1.5 times; Mn in 1.7 times; Cd in 1.8 times are higher than in control. In chernosem southern are detected, that contents of Zn in 1.4 times, Fe in 1.6 times; Pb in 1.9 times are higher, than in control. Mobile forms of the heavy metals, entered to soil with atmospheric air, migrate to it the deep about 100 cm. Aerogenous entering of the heavy metals to the soil depend on the dust levels in air. The hydrogenous entering of the heavy metals to the soil depend on contamination level of the ground waters. Key words: heavy metals, soil, mining region |
