Ecological and Geochemical Features of the Distribution of Trace Elements in Virgin and Arable Chernozems

Abstract

The dtstnbuluxi o f manganese and anc m virgin and arable chernozems located near technogenic objects o f the mining enterprise was analysed Soil sampling was earned out from soil sections The analysis o f soil elemental composition was carried out by xray fluorescence method MathemaUcal processing o f the results included the use o f flandud software packages for statistical calculations h was ascertained that /л belongs to die dements o f concentration and Mn-to the elements o f the dispersion Exceeding* in relation to the maximum permissible or approximate permissible concentration» were not detected, but the concentration o f manganese was above the background The coefficients o f radial differentiation ui the upper horizons of sotls for a ttc are higher than for manganese and they are higher on virgin land than on arable Concentration-, o f the studied elements in the upper layers o f soils are weakly connected with the impact o f dumps and tailings The acid-basic property o f soils is the significant factor influencing the distribution o f the studied elements. Humus content and the amount o f silt in soils hav e the weak influence

Effect of the Cultivation Method and the Distance from a Steel Mill on the Content of Heavy Metals in Bell Pepper Fruit

“…The minimum values were similar to the average manganese concentrations (541 mg•kg −1 d.w.) determined for chernozem soils by Labaz et al [35], while the maximum concentrations were below the acceptable limit (741 mg•kg −1 d.w.) given by the same authors. However, the Mn concentrations in the soil were more than 30% higher than the values reported by Novykh et al for the geochemical background (416 mg•kg −1 ) of chernozem soils of the Kursk region [38]. The average chromium concentrations in the soil in the study areas ranged from 23.8 mg•kg −1 d.w. to 31.91 mg•kg −1 d.w.…”
