THE ELEMENTAL COMPOSITION OF CHELIDONIUM MAJUS L. URBAN ECOSYSTEMS (FOR EXAMPLE, NOVOSIBIRSK AND ISKITIM) ^{[№ 10 ' 2015]}
Researched and evaluated for hygienic and biogeochemical criteria content of 30 macro- and micronutrients in soils and plants Chelidonium majus L. (aerial organs, roots) anthropogenically modified areas. Excess of chemical elements, normalized by GN and SanPiN, not detected. The calculated coefficients of biological accumulation, and root barrier. A comparison with literature data and elemental composition of pharmaceutical raw materials. The content of chemical elements (CE) in the studied soil samples corresponds to the background quantities in the soils of the South of Western Siberia. The excess of the tentative allowable concentrations of total content of CE of the MT 2.1.7.2511-09 and maximum permissible concentrations of their mobile forms of the MT 2.1.7.2041-06 not found. In the soils of city Iskitim statistically significantly higher total contents of B, Ca, Si, P, Sr, Zn, but lower — Na; also detected elevated concentrations of mobile forms of Ca and Sr, which is the reason for the decrease in the mobility of the group of heavy metals (Cd, Co, Cu, etc. In the aerial part Ch. majus statistically significant difference in the content of CE is absent. Probably, the content of CE in plants Chelidonium majus L. has a greater impact relative constancy of the elemental composition of the species. Content of heavy metals in the samples of vegetable raw materials (see table) not exceed the maximum permissible values, normalized by SanPiN 2.3.2.1078-01. All the studied plant material complies with the standards of the State Pharmacopoeia by the total ash and ash insoluble in 10 % HCl. When compared with the percent abundance values in plants the land, in the samples there is a high concentration of Al, Cd, Co, Ga, K, Pb, Sr, and low — Cr, Mg, Mn, Na, Zn, Zr. However, the content of CE is the same as that in the samples of plants Ch. majus from the European part of Russia, Belarus and Ukraine. Samples of pharmaceutical raw materials Ch. majus differ in content Co, La, Cr, Ni, Mn and Zn. Our results confirmed Cu and Zn concentration in aboveground part of Ch. majus. High values of the coefficient of biological absorption observed for K, P, B, Mg, Ca, Sr and Cd. The ratio of the root barrier is less than unity for B, Ca, K, La, P, the maximum values are typical for Al, Cr, Fe, Na, Ti (highly variable).
