Picture 2 shows the average content of mobile forms of heavy metals in soil, sampled from the production areas. The average content of mobile forms of the investigated elements in soil gardens above the average concentrations of these metals in the soil of industrial areas – on the Ni and Cu in 1,2 times; Cd 1,5 times; Mn 2,0 times; Pb 2,7 times; Zn 5,5 times. Perhaps this is due to the uncontrolled application of mineral and organic fertilizer to the soil of private farms residents, which could adversely affect the quality of the grown crop production. 170 CONTEMPORARY PROBLEMS OF SOCIAL WORK Concentration, m g/kg Picture 2. The Average Content of Mobile Forms of Heavy Metals in the Soil of Industrial Sites As the data in the literature review, the most negative effect both on the productivity, and the chemical composition of the plant have movable mold heavy metals. The total contamination of the soil is characterized by a gross amount of heavy metals, the availability of components for the plants is determined by their mobile forms. Therefore, the content in the soil of the mobile forms of heavy metals – the most important indicator of the sanitary-hygienic situation in the given territory. [1; 2; 7; 9] The results of the studies show a very large share of mobile forms of Cd and Mn in all the studied areas, which primarily may be due to high technological forms part of the movable elements (Table 10). Table 10 The Content of Mobile Forms of Heavy Metals, As a% Of Gross Indicator 1 st zone 2 nd zone 3 rd zone Pb 3,8 5,6 5,3 Cd 29,3 81 47,5 Cu 0,6 0,2 0,4 Zn 0,9 0,9 0,7 Ni 1,4 1,4 1,2 Mn 12,4 13,9 14,6 Cr 0,7 0,2 0,2 Fe 0,02 0,007 0,005 The vegetables produced with gardens, and milk, taken in the private sector, measured normalized elements – Pb and Cd, regional pollutants – of Ni, Cr and Cu, Zn, Mn and Fe. These data suggest that of the investigated products, according to the average content of the studied elements is secure by Cr – potatoes in all areas of the research; cabbage in the first zone; carrots in the third zone (Table 11). Chrome, obviously, is a regional pollutant vegetables. According to calculations, 20 carrot samples, 80 – potatoes, 10 – 260 beet studied contain Cr in concentrations exceeding the MPC (Table 12). 171 VOLUME 2, No. 1, 2016 Among other elements exceeded maximum permissible concentrations of Cd in 10 potato samples, 20 samples of beet; Zn by 10 samples beet; for Pb and Ni samples exceedance is not detected.
