Abstract

Ecological state of the territories with different levels of transportation and industrial pollution in Novosibirsk Oblast with the help of plants Hemerocallis hybrida (cv. Speak to me) was assessed. Application of the method x-ray fluorescence analysis using synchrotron radiation allowed us to obtain reliable data on the content of 20 elements in the aerial and underground parts of plants and soils from the sampling points. The total content of microelements in leaves and rhizomes of plants of the most contaminated sites increased by 3.5—6.2 times compared with the control. It is shown that the magnitudes of the key relationships of elements Fe/Mn, Ca/Fe, Zn/Cu, Sr/Ca undergo significant changes in the conditions of technogenic stress. It has been revealed that the main elements-pollutants accumulating in excessive concentrations in leaves and rhizomes of plants in areas of heavy traffic are lead, nickel, zinc, iron, titanium and chromium.
