The method of X-ray fluorescence analysis involving synchrotron radiation (SR XRF) has been first used at the station of element analysis of the SSTRC of the Institute of Nuclear Physics (VEPP-3 store ring) to analyze the content and composition of elements in soil and plant samples growing in places with the different level of pollution in the Novosibirsk region. The plants Hemerocallis hybrida (sort Speak to me) growing near the industrial enterprises and highways of Novosibirsk, urban-type locality Koltsovo, and the town of Berdsk were the objects of a given study. The territory of the Central Siberian Botanical Gardens was taken as a control site. A comparative element analysis was performed both for the leaves and rhizomes of H. hybrida, collected at the end of vegetation at the control and seven experimental sites, and for the samples of soil on which the studied plants grew. The SR XRF method provided reliable data on the composition and content of no less than 20 elements of ground and underground plant organs and of the soil from the sampling sites. The peculiarities of the composition and content were revealed in the elements of the vegetation organs of Hemerocallis hybrida, growing under a technotronic impact depending on the level of pollution. It has been established that the total content of microelements in the leaves and rhizome of the plants from the most polluted regions around industrial enterprises and along highways increases 3.5-6.2 times as compared with control. It is shown that the values of the ratios of the key elements Fe/Mn, Ca/Fe, Zn/ Cu, and Sr/Ca change substantially under technotronic stress. The level of the accumulation of micro- and macroelements was determined to depend on the peculiarities of plant organs and on the polluting strength of the region, in which they grew. It has been established that Pb, Ni, Zn, Fe, Ti, and Cr are the main elements-pollutants accumulated in excess concentrations in the leaves and roots of the plants growing in the zones of strong traffic. Using Hemerocallis hybrida we have estimated the ecological state of the territories with the different level of industrial and transport pollution in the Novosibirsk region. It is demonstrated that Hemerocallis hybrida of the Speak ty me sort can be used as a bioindicator of industrial and transport pollution.
