Evaluation of the Elemental Composition of Hemerocallis as a Bioindicator of the Ecological State of the Urbanized Environment
As a result, the study using the method of x-ray fluorescence analysis with synchrotron radiation (SRX RF), for the first time obtained reliable data on the content of 20 elements in the above-ground (leaves) and underground (rhizome) plant organs Hemerocallis hybrida (sort Regal Air) growing in an urban environment in the Novosibirsk oblast. It is shown that the maximum concentration of most elements falls on the organs of plants that live in a man-made environment. The high content of heavy metals - lead, zinc, iron, manganese, copper - in the leaves was noted. The increased concentration of chemical elements in the organs of plants Hemerocallis hybrida, which suggests that they are bioindicators of the ecological state of industrial transport zones.
