Results of the study of the coefficient of biological absorption of heavy metals, such as lead, nickel, cobalt,
zinc, iron, manganese, calcium, strontium, and copper by leaves and rhizomes of Hemerocallis hybrida (family
Hemerocallidaceae) are presented. Elemental composition was determined by x-ray fluorescence analysis
using synchrotron radiation (XRF SR), based on the interaction of matter with high-energy electromagnetic
radiation SI. The absorption of the above elements by the vegetative organs in the cultivars Regal Air and
Speak to me grown in the urban environment was analyzed. The variability of the coefficient of biological absorption
in the aboveground and underground organs of these elements was studied. The comparative analysis
of the coefficients of biological absorption of heavy metals by leaves and rhizomes of Hemerocallis hybrida
grown near seven industrial areas, motor roads of Novosibirsk and Berdsk was conducted. It is noted that the
coefficients of biological absorption of lead, nickel, cobalt, zinc, iron, manganese, copper, in urban growing
conditions are higher as compared with the control plants. Individual variability of the coefficient of biological
absorption of these elements in underground and aboveground organs in control and experimental variants
was established. The coefficients of biological absorption of zinc, cobalt, nickel, manganese, copper by leaves
of kinds of Regal Air and Speak to me from the experienced samples grown close to the motorway and industrial
zone (seven variant) of reinforced concrete are the highest compared with other variants. The coefficients
of biological absorption of these elements by leaves of Regal Air 1.2–1.8 times higher than Speak to me was
discovered. Sort specificity in the accumulation of heavy metals in vegetative organs was marked.
