英文摘要 | Relevance of the research is caused by the necessity of obtaining up-to-date data on concentrations of chemical elements in the "water-soil-plant" system on the near-entry spot of tunnel 504 of "Degelen" site at the former Semipalatinsk Test Site. During flooding in spring, elements may be carried out beyond tunnel 504. The main aim of the research is to study spatial distribution of chemical elements in the "water-soil-plant" system in the streamflow of tunnel 504. To achieve this goal, the following tasks were set: 1) determine concentration levels of chemical elements in water; 2) study concentration levels of chemical elements in soil; 3) identify features of chemical elements accumulation in plants of tunnel 504. Methods. The ultimate composition of water was determined by inductively-coupled plasma mass-spectrometry (Elan 9000 "Perkin Elmer SCIEX"), inductively-coupled plasma atomic emission spectrometry ("iCAP 6300 Duo" Thermo Scientific). The analysis of such indicators as total mineralization, the content of sulfates, hydrocarbonates, chlorides, calcium, magnesium and sodium was carried out using titrimetric, colorimetric, potentiometric techniques in accordance with GOST. Results. The analysis of the data obtained for water showed a high content of such elements as Li, Be, Al, Mn, Zn, Rb, Sr, Cd, Cs, La, Ce, U the average content of which exceeds the clarke several times for groundwater of the arid climate (sulfate water). The excess of maximum permissible levels of such elements as Be (2800 MPC), Mn (260 MPC), Al (76 MPC), U (70 MPC) and Cd (50 MPC) has been registered for water. According to the latest data, the content of such elements as Li, Be, Al in water was found to increase by 2 times whereas that of Co, Ni and Cu - by dozens of times. Spatial distribution of elements of interest in soil of tunnel 504 is non-uniform. Most of elements are concentrated in soil to the north of the streamflow bed. An elevated content of such elements as Be, Mn, Cu, Zn, Mo, Cd, Cs, Pb and U was detected in this area exceeding the clarke of lithosphere. The high index of lithosphere clarke value excess was found for uranium concentration (1000 times). Comparison of findings for contaminated areas with values of maximum permissible concentrations of chemical elements in soil showed the excess for Pb (26 MPC), Mn and Cu (9 MPC). Chemical composition of water and soil of tunnel 504 is unique by the content of rare-earth elements. The average content of REE in water exceeds the clarke by thousand times in ground water of the arid climate and STS ground water. The excess of the maximum permissible concentration level of samarium was observed in water. Predominance of light REE is characteristic, with a pronounced cerium-lanthanum feature. This fact shows that metals in water originate from natural sources. For most plant species of tunnel 504 an elevated content of Be, Cd, Cs, Pb, U and a number of REE was detected in the contaminated area. Concentrations of elements of interest in such plant species as reed and bluejoint in areas being compared, varied insignificantly which is apparently attributed to some physiological and biochemical mechanisms that impede the intake. Based on the above, one can conclude that spatial distribution of elements at tunnel 504 is first of all related to chemical elements carried out by tunnel water. About ten elements exceeding clarke values and maximum permissible levels were detected in water of tunnel 504. |
