Реферат: | eng: The total content of 35 elements has been determined in the bottom sediments of the Magnitogorsk reservoir using SR XRF, and the number of mobile forms of 10 metals has been assessed using atomic absorption spectrometry. The characteristics of incomplete data statistical analysis as well as the reasons of similarity and discrepancies of data obtained by different chemical analytical methods have been considered. Four paragenetic associations of elements have been revealed using principal component analysis in the structure of bottom sediments: those related to organic matter, to the pelite fraction, pollutants from Magnitogorsk Iron and Steel Works, and motor transport pollutants. © 2010 Pleiades Publishing, Ltd.
